Late 80's cams in an early 3.0?

[ber911]

When rebuilding my motor can I use a pair of cams reground on late 80's cores in a 3.0 Euro carrera motor? If so what other parts relating to the cams will I have to change over?

You'll need the bolts and big "washers" for the end.

Pelican parts #'s J-082-072-01 (bolt) and H-105-163-00 (washer).

ALL SC & Carrera &Carrera 3.0 cams are the same grind. The just used a 6&deg range of different timing specs.

I think he said that they were "cams reground on late 80's cores" i.e. not the stock cam grind.

Yup Chris, more radical cams for a high compression motor with carbs. From your post I understand that I just need to get the two bolts and washers to replace the old nuts and washers.

Yes, that is my understanding at least. I've built motors with both kinds of cams but never "converted" between them.

The cams I have in mind are GE80's but have been ground on late 80's cores.

The late cores will work by changing the attaching hardware.
I have 3.0 billets with the nut style snout that will accept any grind.

I'm assuming we're not worrying about piston clearences, etc.. for purposes of your question?
