My drag car has a 351W. I've done the heads(I've got the 1.84/1.55 valves-'69 heads, motor is '70 351W. I'm running a hyd.544/.244 Comp Cams bump stick. Compression is 10.7 to 1, single plane intake. I'm running a Holley 4777(650 dbl.) I've got 74's in the front and 79's in the rear. Out of comparison with my driver and this motor my guess you'll end up with 68 jets. What you need to do is go ahead and save yourself money in the long run by buying a Holley jet kit. Those only run about $40.00. By the time you buy jets singly, you'll end up spending more than that. Let us know.
