Compressor Surge

Pretty badass ride, man. People don't expect these old trucks to cook at all.

What exhaust manifolds did you use on this build? Looks good.

They were stainless shorty JBA 99-07 silverado headers and then I cut them up. Same thing as flipped truck manifolds just stainless.

Got it all back together and put some miles on it. 7500rpm and 20ish lbs of boost makes for a wild ride. Had to back the boost down as im blowing through the conveter and instantly pegging the limiter.. Once the bugs are worked out it should be a good time. Burnt 10 gallons of E85 after about a 15-20 mile tuning drive.. ouch

I saw ya out on cruise night for a little bit

What were you driving?
Yeah I took it for one lap and then parked it... Its just way to loud. Im gonna do some mufflers on it today if I get time..

I was driving the maroon 70 shortbox. Didn't sound that loud at all when you drove by,thought you had mufflers on it.

Damn that is a nice truck. Like the stance and drive train choice!

It must be quieter outside than in the cab then cause I think I went deaf after just that short drive.. I put 3" exhaust on it with Dynomax bullet mufflers today and its quieter but I hate how it sounds now looks like another set of mufflers for the shed.

Thanks.......

Had to get a little tire smoke smell in the garage before I took the carb off to send to CSU for some mods.

What are the details on the rotating assembly? Im guessing you used a 4.8 crank in a larger bore motor. Are you still using the stock rods? Cool truck man it really looks and sounds bad ***. I really like the idea of a short stroke, high rpm turbo motor.

lookin good!

Very very cool truck! Like everyone, I dig the mint. I am also curious about the engine specs as I would love to do a big bore/short stroke turbo motor.

You can go about it in a few different ways.

#1 Lunati rods and JE pistons will get you there if you deck the block.
They have a few different rod lengths and compression heights to make it work.


Cheapest way is bore a 4.8-5.3 block to 3.905
Run GenIV 4.8 rods with Manley Pistons #592007C-8.. Mahle makes a set that works too.
Run a stock 4.8 crank and have everything balanced and use the proper thickness of head gasket depending on your deck height.

Are those actual Garrett turbos, or eBay knockoffs? Compressor/turbine specs?

knuts82

They are ebay gt35's
61mm comp.
62mm turbine

I have a bench full of Garretts ive trashed and figured id give these a shot and so far these ebay gt35's are working great..

knuts82

I can't wait to get my carb back!!!!

Truck looks sad..


It wants more of this..
