Need 1 3/4 long tubes for my 347
 

Looking for a set of 1 3/4 headers for my 347 with Twisted Wedge heads. What brand would be the best flowing and make the most hp? I have a C4 so they got to clear the tranny.

88 347, Twisted wedge heads,Comp Cams 224/230 cam, 1/4=10.718 @ 123.02 mph

Did you ever up your compression ratio?

Skyler,

I have 9.9:1 compression ratio. I am not sure but maybe these shortie headers are holding be back as this engine just doesn't pull above 5000 rpm. With this cam it should. I have ported the headers good and open them up to 1415 exhaust gasket but something is causing the hp to fall off at higher rpm.
