Roller CAMs began in 2000


Recommended Posts

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?

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. I forgot about the dogbones

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.
