1972 350 no power after rebuild
Hi I'm new to this form and to Buick's. I'm helping a my best friends dad with his 1972 Skylark 350. He had the engine rebuilt and the pain begins. This engine has no power beyond 3300-3500 rpm has no HP at all! I have idling good seems to run fine but gives you nothing when you get on it here is a list of stuff that has been done to this engine.
1. Heads where mild .0010? not sure but they where done
2. Bored 0030 over
3. line honed
4. reconditioned crank
5. TA C110 cam
6. TA stage1 intake
7. TA stage valve springs
8. New fat pistons
9. 600 Edelbrock
10. the engine is bolted to a 200r4 and has 4.11 rear end
Help this thing really blows:confused:
