fot 1 to TDC lashed the propper ones, put the plug back in pulled 6 roll over and guess what no freakin compression what so ever!! the only abuse this car has seen was on the dyno last year all i have done since is cruise it around... ill never buy a pre built car again everything the previous owner has modified ive had to fix or replace! now the motor... sad part is the car still has tons of power it seems so where gonna run it down the 1320 on 7 and send the motor to its death good and proper. good think i have 2 spare blocks!
motor details are splayed 4 bolt caps, GM forged crank, eagle SIR rods and wiesco 8:1 pistons...

 

I graduated in 1973 and I still comprehend what you said.

 

That's the problem with a used car, you just bought someone eles's problem, bummer.

 

No compression is usually from a open valve or a hole in the piston. I would check your valve lash again
