Depends on quick you want to go. I have an old Dyers set-up. It's a 6-V71 mounted on a modified 4 barrel intake. motor is a 340+.030",245@.050" cam,ported stock heads,7.8-1 compression. With a 9" converter,4.30 gear,drag radials. 11.17@121 thru the mufflers in a 3850lb Volare. The blower is loose and worn beyond clearance specs. I run it 9% over at 12 lbs boost.
