396/375 hp/motor issues

[Run to Rund]

Definitely check out the ignition as noted above. As a last resort, the carb to intake, or intake to head gaskets could be leaking vacuum.

hope to change out distributor tommorrow...changed the advance springs in the current distributor from light to medium to heavy.....light is just simply to light and a great deal of difficulty cranking.heavy is ok ,but slow gettin to the desired timing mark from the dyno tuning ,tried the medium spring ,but when timing mark was set at the 40 degrees under a load,the intial timing at idle was just too low and the car ran crappy...hopefully the distributor change wiil do the trick..the 396 nova has 11;5;1 compression .via purestock drag rules... and a msd 6a.
