That's real similiar to your build, and figuring 15 percent for drivetrain loss your numbers should be real close to what your wanting

i think you will have a hard time getting 350 ft/lb torque out of that combo. also what is the gear ratio? the right engine with the wrong gears will fall flat on it's face

3.73 gears with 700r4 trans.

care to elaborate?


A truck has a lot of loses in the drive train, on a calibrated chassis dyno I don't think you will get there with that engine combination. IMO chassis dyno numbers mean nothing, but are only good for tuning the entire combination.

I agree on both accounts. I dont expect it to ever see a dyno of any kind on my budget.

I imagine my loss will be in the higher range. Its a longbed with no supporting mods to help deliver the power where needed.
Thankfully HP isnt my main concern as much as torque. The truck will never rev past 5-5500k, intentionally anyways.
I am a bit concerned with the fact that the parts I have are intended for a 1800-6500rpm range and Ill have relatively low compression. may make getting out the hole a bit soft. IE torque concerns!!

My saving grace...( as previosly mentioned by one of the responders), Is that I will be undoubtedly doubling the numbers across the power band when compared to the anemic and worn 305 that is currently in it. I expect to be happy regardless when that is considered. Numbers Shmumbers it should be a good driver...I hope!
