new motor build question
Its going to be a 383. With the milled vortecs I have, it will put the SC right around 11:1. But my DC with the cam will be around 7.3:1. My quench will be .040-.045". My question is, will the motor be able to run on pump gas with that much comp. and iron heads?

That DCR is definitely low enough for pump fuel. It shouldn't be a problem until your DCR goes above 8.5:1, and I think there are some motors I've seen around 9.5:1 still on pump gas.

So it doesnt matter if the heads are iron or alum. I just keep hearing the folk lore that high comp. and iron heads dont mix. I thought that with such a low DCR it wouldnt be bad. Im still learning all of this stuff so bear with me.
