I bought a 1986 GMC C15 for a budget midlife crisis project.
Plan is to install a 383 stroker, but the driveline needs some upgrades first. It has a factory 3.42 rear end, but I need to install posi. I know I can get the parts for +/- $500, but it sounds like a bit of a technical install. Any advice for DIY, or cost estimate to have it done?
I know the 700R4 needs a rebuild/ replace to handle 400+ HP and 425+ TQ, but costs are all over the board. Anywhere from $1300 on Amazon to my local transmission guy who says $3-4K.
Just looking for any advice or experience with either.

Add weight to the bed.

The end goal is to turn money-into-rubber-into-smoke, so that might be counter productive! :chuckle:
Although keeping a few sets of rear wheels and tires in the bed might kill two birds with one stone!

Making quality - reliable smoke always costs money. :twocents:

You may want to see if you can find a kit to replace the rear end with a 9" ford rearend kit. More expensive than you've stated, but strong and if you want to swap gear ratio's they're easier to deal with. I put one in a 68' elCamino, very happy with it

Buy a diesel, make smoke, and save on the rubber. :)

I can't ever see it hooking up well enough to blow through an 8.5" 10 bolt.

Sounds like that local transmission guy got a big bone when you told him what you were doing. Sounds like a fun build project.

Ya, everything sounded great until he through out that number! I try not to come across as a guy that has fat stacks of cash, which is pretty easy when you don't have fat stacks of cash!
Here she is. Plan is to keep the look completely stock, with the possible exception of a very slight lowering.

383 is great choice. Get good heads on it for power. Its all about the head. Spend your $ on good Heads... 10 bolt is fine (300hp) and plenty strong, spool or Detroit it. Or find a 3/4 or 1ton rear which may solve your gear issue too! Watch frame by PS as prone to cracking. Had a few Ol Chevs over the years. favorite was 1971. A 350 with good parts (head) is good choice as well. Don't buy some cheap Box crate engine, they lack power(heads). 700 is good trans when rebuilt by exp techs. I would think 1200-1600$. My guy did a T350 for me for 600$ and I shoved a 455 through it no problems. But he retired and was a friend. Honestly if you plan to keep it under 100mph a 3/4 ton gear with locker/spool and tubbed with 400+HP would be very quick and kill tires. :twocents:

Currently looking at a GM Performance Parts SP383, rated at 435HP, 445TQ, brand new straight from the factory with warranty.
Other is a Smeding Performance 383 rated at 400HP, 440TQ. They also use brand new GM blocks, and nothing re-manufactured.
Time (and $) will tell...

TCI has a street fighter 700R4 that will easily handle what you're doing for around $2k. :twocents: If they're still producing the same quality they were 20-ish years ago, I think you'd be happy.

Don't even paint it and put an old canopy on it. That will make it all the sweeter when you blow the doors off all the imports puffing their chest these days.

Navigating online reviews is a bitch. Website A says TCI Streetfighters are the bomb. Website B says they’re junk. It’s like listening to Ford/ Chevy guys. For the record, I have a Ford and a Chevy (well, GMC)!Don't even paint it and put an old canopy on it. That will make it all the sweeter when you blow the doors off all the imports puffing their chest these days.
Oh, I have no intentions of painting it. Maybe some wider rims, but stock looking rally rims.

Plus you'll get a sticker. Your local rebuilder guy gonna give you a sticker??
Since this is not going to be a daily driver, another cost savings option is to ditch the 700R4 and go with a built TH350 for roughly half the money. Do you really need that overdrive gear for the extra money? You could likely sell that good running 700R4 for a pretty penny and get into a built th350 for peanuts. I thrashed the snot out of a TCI th350 with a pretty loose converter behind a stout small block. Held up for me, was happy with it.

Yer damn right I want a sticker! And it comes with a chrome pan with a logo on it, you know, so the pizza faced kid in the pit at Oil Can Henry's can get all worked up. I've thought about switching it out, but the OD is nice on the highway, so if I ever want to go fishing in Alaska or something...
-
That all makes good sense to me! :chuckle:
You should go fishing in Alaska, I know a guy.
-
Keep the OD. Nothing sucks worse then cruising at 3500 r's on the highway all day long. Don't forget to look into a different stall converter. Check ebay for heads. Be careful on getting a DIY port and polish job. I like the 383 but its has a bit too much stroke for me. I like to wind them tight and listen to them scream. I would do a 327, duntov cam, best heads I could afford. 4 bolt main block. I hate trannys. They blow up no matter what when u push 500 HP thru them. I love projects like this,

I'm on the opposite end of the power band. I'd love a motor that I never need to take over 4500 RPM.

Ah, contraire mon frére! On the street, the vast majority of my time will be spent well under that.
-
Of course, with the lower rpm range, I'm thinking "there's no replacement for displacement"... Since I'm building a big block for my own flatbed - should I build two?..we could do a nice streetable 454 for just north of $2k, or great pump gas 496 that will deliver at least 550 ft# of torque from ~2000-5000 rpm (peaking over 600) for well under what a new SP383 goes for. :chuckle:
-
The world is moving to LS motors for a reason. They scream! Had a 425hp 350 small block chevy and LS crate motor just blows it away. Lighter too.

You haven't ridden in the right LS rig yet. Let me know when you are back south. I know a guy. :chuckle:

Of course this is just like Brad Pitt and George Clooney arguing about who's girlfriend is hotter. If a big block or an LS motor just showed up on my doorstep, I'd be renting an engine hoist!
(Keep that in mind if you draw me for the Hunt Wa gift exchange this year!)

I was thinking more of the 6.0 LS6 from the Z06, but that will SCHWING!!!

Throw a turbo at it like the 405! Better yet do a Cummins twin turbo conversion and spank em all while running under 4000rpm. :tup: Seriously you will not have traction for 500hp.

Had a long talk with a transmission builder yesterday. Sounded like he knew what he was talking about, and was very detailed about planned tire size, rear end ratio, motor specs, etc. However, he was very set on a non lockup converter, witch goes against just about anything I've read for street applications. Anyone have any experience with this? I've got a decent handle on how things work, but automatic transmissions are out of my wheelhouse.
-
Never owned one, but I know the guys I ran with ditched the lockup because of their weight. They are monsters. Anything you can do to lower the weight of the reciprocating mass will improve acceleration. I'm sure there's a reliability issue when you start making big power as well.
If you go non-lockup, you'll generate a bit more heat in OD, increase your RPM slightly, and lose a bit of MPG vs a non-lockup.
Did he cite any specific reasons for the non-lockup converter?

I have to call him back. I was on information overload! My number one concern is reliability.
-
Virtually impossible to kill a non-lockup converter, unless you get crazy with the NO2.
-
My (again, limited) understanding is that it's not about the converter grenading, but about transmission failure due to overheating from slippage, which was an issue with the 700R4.
-
If it were me and I had your vehicle it would be one of two options, either a 406 with 350 vortec heads and a nice cam with F.I. (Easy 450hp) or a nice 6.0 with a slight build and easy almost 500hp with a 4L60E/4L65E built behind it. They both make tons of HP and good torque and the transmission with a nice build will last a long time.
Just finishing a 64 SWB with a 6.0 with a 4L65E and all computer controlled and will make almost 500 at the flywheel and my wife can drive it to the store or Olympia and get almost 20 mpg and will fry the tires through the first two gears easy.
Also have a 72 SWB that had a straight six and a three on the tree that now has a 454 and a TH400 that will fry the tires as long a I press on the loud pedal but it gets 6-8MPG and revs alot if I drive it 70mph but it is fun as hell to drive.
Def go with a o/d with lockup as it will keep the trans temps down and temp kills transmissions.
-
Add weight to the bed.
:yeah:

Dropped the rear a couple inches to level it out. Through some headers on last weekend. I figured I'll need them for the new motor, so I might as well make some noise in the mean time! (yes, I realize I am a poser!)
New radiator come in tomorrow.

That looks sweet!

Nice truck buddy!
Looks just like my dads last square body Chevy when I was a kid!

Thanks!
Here's a little update:
Getting close to having everything I need in order to drop in the engine and transmission.
Bought a new aluminum radiator and B&M transmission cooler (will install with new engine so no old fluid)
Bought an Eaton Truetrac posi, Richmond 3.73 gears and all bearings. (Scheduled for install 6/5)
Installed a 1 3/8" front sway bar. Man what a difference!
Finished installing full Flowmaster exhaust system with Super 44s yesterday.
450HP/ 460TQ 383 Stroker and 700R4 transmission built to match should be here in 5-6 weeks.
Just need a few odds an ends, like tranny temp gauge and tach.
-
That thing is gonna haul some serious ash. Firewood.
You going to flog that 305 to death before you yank it? I've always wanted to zip tie the throttle open on one of those and start the timer...

I'ts been getting a fair amount of abuse already. I'll tell you this; 165 ponies does not do justice to 2 1/2" exhaust and a pair of Super 44s.
At this point I'm a total poser. Maybe I'll use it to build a blender for making daiquiris!

My mom tells a story of my old man trying to blow up the motor on an old Ford falcon he had after they finally bought a new car like this. Said after about ten minutes he gave up and drove it to her brother's house and sold it to him. He claims it was the longest the thing ever ran without breaking.
Sweet looking truck. Love those things that don't look like they move and then before you know it the things gone. All substance and no show.

I think a plywood bed in back would help. I can help you there.

Well, all I have to say is 5-6 weeks my butt!
Motor is finally done, and pulled 453 HP and 473 Lb/Ft on the dyno this morning. Will ship, along with tranny, from Texas this week.

Wow man, that looks great. Impressive numbers. Really cool to see a Holley 3310 up there too.
That is yer classic, street/strip Gen1 SBC, right there. Excellent choice :tup:

If that is the case, don't go any closer to the posted speed limit than 15 mph under every where except in town and keep one blinker and the high beams on at all times!
