Engine shakes BADLY!!

With that cam that engine is probably gong to want 20*- 24* initial timing. Your going to have to get a new advance bushing or make your own. I would set it up with 34* all in by 2400 RPM.

Not enough initial timing will also make it hard to start and it will be lazy.

Ignition first, then tune on the carb. In that order or you will chase your tail.

That car sounds pretty damn good by the way!

The mutha thumper cam ,intake .497 lift duration 287

exhaust .483 lift 304 duration

And 34degrees total is more than his edelbrock heads with a modern combustion chamber need 32 degrees should be about right .

Now if he was running iron heads with an open chamber he would need the 34 degrees or more to get the motor to rev

isn't large enough to warrant that much timing and it would idle awfully high at 18 + degrees.

As far as a lazy rev the timing curve done correctly will take care of that


And to much initial timing will make it hard for the starter to crank thus hard to start also
