What kind of compression is that thing pushing now? I know stock was in t he mid 8s.....are you using a domed piston?

[cmwilkecm]

@dnazz32 11.5 compression with Ross domed forged pistons.

I've seen powerful pontiacs with demons but i know holleys pack a punch too. i am building a '66 389 of a GTO but all i need is the carb...what might be better for a cam with 237 duration

[cmwilkecm]

@marioalonsojr You could go with a 750 jetted rich or an 850 jetted lean. Or have you already decided? Sorry about the wait.

7F6 i guess,what is max flow at 28 inches?

[cmwilkecm]

@plopzzzzzz 1972 7F6 455 HO. Exhaust crossovers are filled with a complete port job. Doug Nash intake. I ported and gasket matched everything. Sorry I do not have flow numbers readily available. Sorry it took me so long to respond.

it will be nice to see old TRICK '66 rippin' up the track again, plenty of victims fell to the wicked trick '66 on hy100 back in the day.
