Here's what that page spits out for my current compression/cam
Quote:
Your dynamic compression ratio is 11.21:1 . Your dynamic cranking pressure is 244.55 PSI.
So it's safe to assume this WON'T run on pump gas
LOL
i know a guy a couple miles from me with an iron headed 390 and around 225 psi on pump 93.
But 244...likely not.

With a dynamic CR of 11.21, I gotta ask ... what's your static CR ????

E85 cornfed bigcube dart maybe?
If they had it around here I'd consider it. But I really want to tame it down some and drive the car more. I've always ran VP C-16 in it.

If you replace your current headgaskit with something like a thick copper one and gain .080 or so where would your compression be? I'd run as much stuff as I could if I had what you have sitting around. That thing is fresh so I'd really look at doing as little and as cheep as I could. Pistons would be as far as I would go. Then you could spend the cash saved for 110 or E85 I would stick exhaust with electric cut-outs on it. Cause you know "ice cream is better with open headers".

Yep, been trying to work out all the gremlins ; fuel delivery and the Tq converter been giving me grief !
The car is also real heavy (4200 lbs raceweight) so i'm making some off season changes to lighten things up.

looking great there ron. but i have a question for you.on the mopar 337 intake.did you use it to cover up the valley? i mean did you use it instead of useing the indy valley plate or did the intake bolt on top of the indy plate? sorry for the weared question.but in the pic the 337 intake almost looks like it is bolted on top of the indy valley plate? i might be wanting to try this intake latter on down the road.thanks Mopar65
Bobby, with the raised port EZ heads we had to install an Indy valley cover underneath the 337 manifold. Good eye !

Jim, some pistons, rods, a cam, and a set of valve springs and you'd be right in pump gas/grocery getter heaven
