Engine Performance problem
1979 GMC C1500 V8 Two Wheel Drive Automatic 000000 miles
I have a 1979 gmc truck with a 350. The motor is ike a 74'. Had been over hauled about wanna say 5 years ago lol. By a man I do not know. Ive heard it run about 6 months ago but they didnt spin the tourqe converter. So I snaged the engine for free. Lol. But when I dropped it in I hooked it all up and it runs a little rough the oil pressure is at about 12psi and the vaccum was 0hg changed intake gasket now vaccum is about 10-8hg and oil pressure is about 8 psi. Could I have accenttley clogged the screen with old silicon or just weak pump. If I drop the pan how wold I know. Would timeing effect this. Would missing effect this. Can you help me. Also it has a small new holley carb 4bbl on it do I need to adjust the secondary buttery fly to fix the vac. Thanks
have the same problem?
