i have a comp cam 35-235-3 that i bought for a 351 windsor. I am wondering if it would be safe to run in a 302? i know i will have to change the firing order. I guess i would like to know if it could be a bad or good thing to do? Also i have a set of 1995 gt 302 heads with the head bot holes machined out for 1/2 bots. wondering if it would be ok to use these on a 302. if so any suggestions on what to do about the over sized head bolt holes. The 302 engine is a 79 i think.

 

You're good in both cases, both engines can use the same cams so all you nee to do is change the plug wiring order, and all you need for the heads are bolts with shoulders on them or a bushing kit for the stock bolts..
