Dave1647545494 Posted May 24, 2003 Report Share Posted May 24, 2003 this is an LS1 based motor ,but all iron correct. just wondering if all the bolt on stuff for f-body's and corvettes will work on it. Quote Link to comment Share on other sites More sharing options...

1TrueSS Posted May 27, 2003 Report Share Posted May 27, 2003 LS1 based, yes! I know for sure that the 99 6.0 is all iron. I think the newer ones have aluminum heads and the ones that are in the caddy's and the new SS are all aluminum. Not sure though! As far as the fbody and corvette thing, pretty much every thing is universal, but I think the intake manifolds might cause you a problem with the TB. The intake manifolds on the fbody and vettes are lower than the trucks. The truck intake manifold will produce more torque. Also the 99 Crank is shorter than the 2000 + motors, this will cause a problem with the newer trucks 4L60 and 4L80 trans. Brackets and FRC will need modifications.

Dave1647545494 Posted May 28, 2003 Author Report Share Posted May 28, 2003 I'm looking into alternatives in case my buick blows up again. I'm probably going to take an entire running drivetrain from a truck and put it in the car. I was just curious if the bolt on stuff was all interchangeble. thanks for the info.
