Tell me about ur setup. What boost do u run and what type of HP & Torq are u getting? What heads? Several builders have told me the Radix can't push enuf air for the 402 and u end up w/ too small a pulley generating too much heat/spinning too fast. I had basically opted for the 370 and expect to get aboput 450hp & 500 torque to the wheels. R/

 

Whitt1 is running over 600HP with a stroker radix.He did it

 

Spoke with a local guy today who has done some 408 and 370's around here that have held up well and he quoted me $990 for the labor, assembly, machine work and bearings. I would provide rods and pistons. Sound good??

 

Sounds pretty good...but who's gonna tune it? U can prob drop it in and get it running urself if u have the time, but the devil is in the details. Ur gonna wanna get the max out of it and that takes Dyno time. The biggest expense afetr my motor will be the proper machining and dyno testing. Will the block need boring and honing? will it need decking? balancing? in my opinion that part is more art than tools. Personally, I'm gonna have them put at least 200-300 miles on it before giving it back - all broken in and tuned up. That'll cost more, but its time I just don't have unfortunately.

 

I have HPtuners and a wideband and also have a friend of a friend who is very experienced in tuning combos like mine. The shop is going to hone, clean/ hot tank, and balance. They are usng clevite 77 bearings and have done several builds like mine. Im trying to keep everything reasonable as the new house is going to run $465,000. Priorities suck

 

Sounds like a darn good deal ur putting together! Wish I cud arrange it. I just sent off my deposit for my 370 yest, and on the list for a new J-tube & 90mm TB for my Radix. I'm pretty confident I'll be getting pretty close to my goal of 500rwhp. R/
