Weiand 8023 added to 69 mach 1

[rindel]

Hey Guys,

I just replaced my stock intake manifold with a weiand 8023. So far my 351 has new pistons, scorpion roller rockerts, crane hmv-278-2 cam, weiand intake, edelbrock 600cfm 2 1/4" exhaust & hooker super comp perf headers. I'm wondering what my horsepower # would be with these mods? I'd also like to know if I would see some noticeable additional gains from 2 1/2" exhaust or porting exhaust on heads to remove thermactor hump ?

There is probably a few key pieces to the puzzle that are missing for the engine guru's here to evaluate. Namely the compression ratio.

Heads are the biggest limiting factor on the 351W and again the guru's will be able to shed some light on that.

2 1/2" exhaust as compared to ?? From what I have read (as apposed to personal experience) 2 1/4" to 2 1/2" is about as big as anyone really needs to go on a street car. Even on the mighty 351C in Boss form Ford only used a 2 1/4" exhaust.

Anyway, I'm not one of the engine guru's here so we will defer to them and see what answer is given.

The progress looks great!
