Hello there,

had a friend that's preparing to build a Silverado with TrikFlow CNC heads 225cc / 61cc, 402CID + dual stages of nitrous we're about to get everything done now! but we're worry about the driveshaft and transmission also those who runs converters please feed us with more information that may help us to build it, btw the car will be street car high rolling race and would love to have an good drivability on it.


Best,

As long as you didn't over do it on the cam you should be fine. I'd want a 3k stall anyways myself. Can you list more details about the motor? Compression, valvetrain, intake, ect.

ZeOhhSix

The motor is a LS2 402ci. The parts im using are callies 4340 4.0" crankshaft with indexed & trued journals. Callies H beam 6.125" rods with ARP 2000 7/16 bolts. Wiseco 4.005" nitrous pistons w/anti-friction coating and tool steel wrist pins. NPR stainless .047 3mm rings for reduced friction & high heat applications. Clevite MS2199H main bearings Clevtite CB663 H rod bearings, ARP main studs. Valve job to port work. 1.600 manely one piece intake valves. Viton valve seals. ARP head studs. trick flow CNC heads 225cc / 61cc.

and we're asking cause we want to know what cam size should I go with and if I'm looking to hit the 700whp on that big boy which drivetrain ..etc should I go with.

sounds like no one can help here about the driveshaft and transmission.

I run a th400/ptc converter, custom driveshaft and ford 9". Our combos are completely different so................

What is the goal of this project?

4l80e all day. converter will depend on cam selection. get ahold of one of the many sponsors here and they will help you out on cam specs and converter selection. i run a tooley specd cam and 3600 yank and daily it no problems in a 4800lb ext cab

ZeOhhSix

the goal will be 800HP for that.

I would say a jakes performance 4l80 and a circle d converter for that kind of power.

Jakes or RPM 4L80e with a custom Presicion Industries converter. As far as rear end goes a 9" will be the best bet. Or if he doesnt want to change rear end (which I would recommend) he will need a good set of traction bars, tru trac posi and risk it all (caltracs or assasin style traction bars).

As far as cam goes call Martin @ Tick Performance. He has some good nitrous cams out there.

that's helps a lot, I think we're going with the RPM 4L80e and as you said. thanks again I'll contact Martin to.
