When a solid rebuild will cost you 2G's or more its a hell of a lot cheaper. Then again people often forget that properly rebuilding an engine is NOT cheap.

ya, if you want to change out the whole drivetrain..
Funny, but I thought I SAID that the Series II/III 3800s used the 60 degree metric bolt pattern, not the BOP bolt pattern...

On the other hand, the 3800 you have probably bolts up just fine to your Fiero V6 trans. It also bolts up to any V6 RWD trans used in the 3rd or 4th gen F-body or any trans used in an S-10 with the 2.8 motor (the 4.3 V6 uses the SBC bolt pattern).

I already have the short block ready but I was wondering if there is a mild cam that might work better than the stock setup.
This one is from comp as a oem replacement. Should be fine.draw thru will be ok with bigger cam but needs less overlap so any large cam will need to be custom ground.

COMP Cams: High Energy™, 240H<br>Excellent Torque, Good OEM Replacement

A look at the spec of the oem gnx cam may help you find a better grind. Sorry no real experience with this system. My brother had a capri with draw thru it did respond well to cam changes but More overlap did lead to it not building boost in first gear and at low rpm. Also have seen a motor cycle with a s&s bolted to the turbo and it ran 7.6 in the quarter. His cam was the biggest that would fit without tossing the buckets off the valve springs.

I would call all the cam manufacturers and get them all to give you a recommendation on a new or custom grind cam. Then compare them up and see whats what. If they all recommend the same thing your set. If they all got wild ideas then maybe best to stay stock. Stock cams will also give the best off idle power and with big trucks that maybe just the ticket.
