So I have Pypes on my 72 E-Body with 318 slightly modified and Dakota exhaust manifolds, slightly ported. They have the X-cross pipe, aluminized and route through the valence.
I hate them. They drone and drone and drone.
Before I spend money on resonators, I would rather swap out mufflers...
I suffer from same issue, after engine is hot. I have a clear fuel filter between carb and pump, and I can watch the fuel evoporate and it becomes bone dry. Have to pump it all back to the carb every time.
Somoneone suggest the intake manifold needs blocking. How do you do that?
