Worth the effort?

Part of this continued in another topic but to sum things up where I am at.

Borrowed a carb from the engine shop, a 750 Mighty Demon. Bog was still there not as bad but mid range and top end? WOW pulled so much harder. Pinging was still there dropped down from the stock autolite 65 plugs to 63 and its all good.

Currently decideing on a new carb as part of the problem -see quickfuel vs Mighty Demon- I think the 750 is where its at but the engine builder and Qickfuel say no.

Also the engine builder swears up and down the cam was degreed and not the issue and its "just the way the car is with that cam and gears" Talked to one guy who stopped in at the engine shop who runs his own place that highly recomends re-degreeing the cam. So looks like later on the front of the engine needs to be torn down.

If that goes no where then I'll look in 3.91 gears.
