69 396 BB Start up problem
Hello all - I appreciate any help you could offer.
I Have a 1966 Impala with a 69, 396 with Edelbrock carb. and manifold with GM HEI distributor (auto trans).
The car had a lifter tick and all new lifters were installed along with new ignition wires and now my start up is going very badly. The lifters were soaked in oil overnight before installing and I installed them by backing off the nuts 10 full turns and re tightening 10 turns. The car sat 3 days before starting was attempted. Now it will only run by cranking the starter a minimum of 20 seconds and feathering the throttle, and at that, it doesn't run on all 8 cylinders (runs on maybe 6)and will not accept any more than about 20% throttle and dies when at idle. There is no backfiring so I am confident of firing order. The timing shows OK - When cranking, it lines up with 6 BTC. When it does start there was no clattering. As a test I then backed all of the nuts out by 1 full turn but it made no difference in the running.
FYI: While installing the intake gasket I used silicone around the water ports only on the head side only. When running I do notice some spatter coming out of the tailpipes and realize there would be condensation, however I am not sure if it's excessive (pics attached and taken about an hour after running). The oil on the dipstick looks OK.
