So I'm throwing a 351w in my 65 coupe, i got the motor mounts like 3 years ago and if i remember correctly these are 67, i also got the hedman headers for this swap i believe the 88660? but they just won't fit, a guy told me that the repro hipos manifolds can fit with the mounts i have but I'm not sure, and i have read that some people have them in this swap, is that correct? Any first hand experience?
