edelbrock victor 7721??

[ford secrets]

looking at a new set of victors 7721 with the shaft rockers, just looking for some info before I buy them, first I am runnig a mustang with a windsor stroker and diamond flat top pistons will the pistons need to be modified, I am pretty sure the heads are 47cc and second I am currently using mac 1 3/4 headers on dart sr iron heads will these headers work with the victors? any help is appreciated, thanks nmra.

The pistons may not need anything(best to check), the headers are not going to work. Most VicSr's use atleast a 1 7/8th header tube, and have a different bolt pattern.

I think the 7721 use a 2.5 wide header pattern. Mac standard header will NOT work.

You also do realize the victor sr head is designed for a larger bore. Larger then a 4.00 or 4.03
