I swapped out the chain today and the old chain was really loose in comparison to the new.I didnt get to drive it with the new chain yet cause I still have to reinstall the fan and the serp belt,but im hoping that my lack of power was at least partially caused by that. Im off work this week till thursday so ill be swapping out the fuel pump for a holley 155 LPH and also installing some 373s.Oh BTW when I was rotating the motor by hand, with the timing cover off I noticed hearing cylinder compression pretty good allmost sounded like it was escaping into the crankcase but I cant see how that could be cause there were no indications of pressure in the CC when the car was running.
