I've got a 79 F-150 with a 532 in it. Current headers are 1 3/4" primaries and 3" collector, flowed by 3" dynomax ultraflow mufflers. How much hp do you think I would gain by changing to headers with 2" primaries and 3 1/2" collector, flowed by 3 1/2" magnaflows ?

Motor spec: 532ci, ported edelbrocks and victor intake, pro-systems 1050 dominator, xr292 cam, 10.7-1 comp.

a bunch

Those headers suck in my opinion. I had a 77 F-100 with a 429 so I know all about trying to find headers. I'd suggest looking into a custom set with at least 2 inch primaries. Dominator carb, big cam, all that good stuff but the motor can barely get rid of the exhaust. Chris

I know Hedman makes a set of fenderwells for my application, just seeing whats the bang for the buck. Thanks Chris D
