BodybyFisher Posted January 26, 2010 Report Share Posted January 26, 2010 Here is a photo of the roller cams that began in 2000 If I recall, there was a change in compression in 2000 also along with a change in the head bolts that now had two different sized threads on them I was pondering the idea of using 2000 heads and cams on my 96. I know there is an issue with the accessory bolt holes, what other issues would I run into, am I insane for thinking about this?

KHE Posted January 26, 2010 Report Share Posted January 26, 2010 The 2000 heads won't have the provisions for the dogbone mounts that you need for the '96. Also, the headbolt length issue from the 2000+ engines may present a poroblem in retrofitting the 2000 heads to the current '96 block. I also would wonder how the different combustion chamber would be handled by the '96 fuel mapping in the ECM? Long story short, I don't think I'd experiment if it were my car.

You confirmed my thinking. According to the link I provided above, better flow was accomplished via a change in combustion chamber shape, with my 96 pistons that might be a problem.

Logan Posted January 27, 2010 Report Share Posted January 27, 2010 Using 2000-2001 Eldorado parts. Dogbones can be added to the 2000 and later version engine. See picture. The holes in the block / head are all there. You just need the brackets. These may or may noy be the same parts used in 1997.
