Bent Valve or Major Vacuum Leak

-
Bob, No down around 1000. Went ahead and had the motor gone thru while it was out. Ended up with a cracked cylinder. So the cylinder was sleeved and heads gone thru with a fine tooth comb. The carb guy made a few changes and it really helped.
 
Went to the local strip yesterday and the car is running fairly consistent 10.30's @ 129. The air wasn't to bad. Still density altitude was 4300" about 2X what our altitude is. Not bad for a small block.
 
Make sure to double check and see that it is not back upstream in the intake manifold somewhere. Stranger things have happened. Would suck if it was and you didn't catch it goin back.

we had this happen with our hemis what "chrysler" was making the cylinder heads awhile back... the seats would fall out and then all hell broke loose...

well one cyl eat some valves then shoved the rest of the valve thru the intake into another couple of cylinders...
