Any body, help me please! A 355 sbc,in a 67' nova,with a mecanical fuel pump. Im getting 6-7 psi when the motor is not at operating temps,185 deg. But when it gets warmed up, the fuel pressure slowley drops to 1 to 2 psi and of course runs like crap! So i have changed the fuel pump,with another performer fuel pump,changed the filter, and a new fuel tank pickup 3/8',all for nothing!There are no leaks, and it was fine for a hundred miles or so. The motor is new,afr heads, holley750dp or edelbrock 750, same problem, 10-1 pistons,performer rpm,headers,hi-per hei dist.gear drive.medium cam, th350 trans.Im so confused, frustrated, because i thouht i could fix it. I thought it was a easy problem!!!Any help would sure be highly appr.
