All,
I'm going to replace my log-style 289/302 manifolds with either (in no particular order):
- Hi-Po manifolds (expensive)
- 351W manifolds
- Shorties (recommendations?)
- and MAYBE long-tube, such as Tri-Y.
The purpose of this car (67 Mustang) is for street driving and the occassional Sunday cruise. I would like a lower-maintenance option, which is why I say "MAYBE" long-tube headers. I would also like to avoid the heat that these put off. Whatever I choose, I would like to get good bang-for-buck. The build is a stock longblock, Comp. Xtreme Energy (256 seat-to-seat, 212 @ 0.050" (.477) intake, 218 @ 0.050" (.484) exhaust; Ignitor, Edelbrock Performer 600 carb & Performer 289 intake.
I may get a bigger cam, which would be Comp. Xtreme Energy (262 seat-to-seat, 218 @ 0.050 (.493) intake, 224 @ 0.050" (.500) exhaust.
I am not ruling out working over my 302 Marine heads (55cc) or getting aftermarket heads with higher C/R and bigger ports, so I don't want to waste $ on a solution that would be limited to my current setup.
Thanks for your input!
