Your welcome. Yes the 55 lb savings is nice if you can swing them financially. Nevertheless I agree with 64Physhy to run the W2's even if they are heavier iron and the compression might be a little high. I'd at least cc a chamber to see how many cc's they are then you could figure what to run for a head gasket thickness that will get you down to 10.5 to 1 which I think it'd run ok on pump gas with that big of a cam. Also as I mentioned earlier polishing the chambers helps a lot on reducing detonation. I bet it'd be 450+ hp with that combo. and run on 93 octane if tuned right.

I like the polishing the chambers Idea. Better combustion + less detonation?
plus this would add a few CC's possibly? I may be going home next weekend (5 hr drive) i'll get the W2's and attempt to cc them. Anyone ever tried the Summit CCing kit? I don't know if i can get the short block together over thanksgiving but i'll try. Once i know how much the pistons pop out and the CC of the W-2's ill decide.

Pardon my ignorance, as i know nothing about cirkel track racing but.........
What RPM were you coming out of the corners at?
what was the max rpm you were turning?

we are assuming that these W2 are iron....or are they alu???
If is more of a race car then street car,(80/20) shoot for 11- to 12:1 and run Racing Fuel! Us the 21 cam and just retard the ign timeing and run 91/93 when your playing on the street.

Now if this is 75% street, well then you would HATE my sugestion above:mrgreen:

The W2's are cast iron. They are older versions with out the extra webbing. I like this idea although The car is definitely would probably be the 75% not that im driving it every day but i do have to drive it a Hour away for Autox's and alittle over 2 hours to any Track.

Oh and i think he would turn 7-7500 cant recall and the old man is probably sleeping.
