Isky 270 Mega Cam P/N 390171

Agreed I’m 62 and am not interested in headers unless I had an all out engine
Years ago I read where a 340 was tested with headers and hipo
manifolds there was a 12 hp difference
I’ll be damned if I’m going to pay 400 plus for something you won’t feel in your seat not to mention extremely high frig factor


That’s because they tested JUNK headers. There is way more than 12 HP in a GOOD header over manifolds.

EDIT: if you aren’t paying 800 bucks or more for headers, you might as well run manifolds.
