where can i find info. on the parts interchangeablilty for different generations??? reason i ask is i bought a 502 cam/lifters/rockers/etc. and im wanting to do a few different things.... maybe find a 502 shortblock and use these parts BUT use my 049 heads/intake..dist. and what ever else... or use this cam in my 454 which is a Gen IV... i got cought up in the "ebay" thing but $200 for the cam/lifter/rockers/valvecovers ain't bad since they are un-used.
