My 2 shoe clutch had the stiff springs & clutch brace set to 2.5 turns in from flush, but my acceleration wasn't great at all. Being in Boston, I need great low-end, hence my pipe choice. The jammer clutch I'm using has the softest springs installed. Clutch seems to grab pretty nice, but has a lot of slippage.
I'm surprise that timing alone could be the reason for all of this power loss and not the squish height! I feel like carb is properly tuned as I see a lot of people with similar setups running between a 72-80 jet. I don't have any airleaks as I sprayed it down with carb cleaner and there was no change in idle.
Sounds like I need to order a timing light to check for timing. If i'm maxing out my temps at 310, would that suggest my timing isn't advanced enough? And do you run a head gasket or should I go no head gasket?
