Re: Rebuilt engine lacking power
Couple things: 93 octane is way too much octane for a stock rebuild, even more so with a bigger cam bleeding off some compression. Go back to 87.
Also, with the cam, did you change the valve springs? Even new stock springs would be better if they fit with the cam but you'd be suprised how easy it is to have valve float robbing power.

Edlebrock copied the Melling cam. Its a 40+yr old grind that I can't understand how people keep using.
