xe 262 h comp

Id go with the xe268 myself. The 262 is on the small side. You've got the cubic inches, why not take advantage? Can still run stock convertor too! Heck I'm running the Hughes Whiplash on the same set up you've got. 360 stock bore, stock iron heads and stock compression with an Air Gap and 750 carb. It's spec'd at 223/226 @ .050 with .512/.518 lift and it pulls like a bear! Love it! I'm running a TCI street fighter convertor with manual 727 behind it but only 3.23 gears and it still blows the 275/50 drag radials off at will all the way through 1st gear. Don't short change yourself!
