i run a 454-r..but i did run a team "g"..the newer team "g"s are better then the older ones...but if i had to buy one i would go with the 454-r.
if you want a worked team "g" dominater flange...i have one you can buy cheap...just pm me..
oh yeah my motor ( 511 ci) ran a 5.99 at 114mph @ 3,000 lbs with this team "g'.....don't know what the 454-r will pick it up ( on gas with same carb) but will find out soon.
