I'm buying an 86 with a 351w in it I'm not sure of what all is done to the motor I just know that it has 69 heads on it with bigger valves, mild cam, intake and 4.10's in the rearend and a c4. The best the car has run was 12.30's dont know the mph with a sixty foot at a 1.7 to 1.8 on some damn dirt track cara tires. I know a guy with a set of edelbrock aluminum heads there either victor jr's or performers there the ones that are really for racing. Also I already have a set of slicks and skiinnies on drag lites. How far into the 11's yall think the car could get with the heads and slicks?
