i need help w/duster engine

I take it she had a jr dragster.

no i fugured that...but "not much faster" must have been a fast jr.?

you know i just noticed the heads flow you stated..They flowed to .600"..
what did they flow..? do you have a chart.i doubt they moved much air past the .590 mark...so again you might not need to even go that big..?

cheapst.
