This engine swap i have been talking about so i can get a better understanding. The 351w exhaust ports sit differently than a 289/302...
So the headers from from lets say HEDMAN which shows a listing for a
1965-73 mustang 351w, would work in my 65 comet? im just seeing my options and what is interchangable with what.

Thanks....

I don't know about your comet, but I have a set of conversion headers in my 65 stang. The engine is still a 302, but their is mucho clearanco between the headers and shock towers.

Yeah, the Mustang swap headers will work on a Comet or Falcon. A 351W block is taller and wider than a 302 but the heads are basically the same.289/302 Headers won't work on a 351W in an early car but if you are using 351W heads on a 289/302 then the 302 headers will work. Confused yet?

Thanks .............

I'll know by this monday on the 351w/C4 combo. The thought of stroking it later on down the road is to hard to resist.

If i dont i will just stick with the 289 and get a later C4.

Thanks again!!!
