Quote: You want to know what is funny and ironic? The car did have aluminum heads on when it WAS legal to do so. When I ported a set of iron heads and put them on the car and kept it a secret, THAT is when the car started getting fast. Hahahaha.
The aluminum heads moved around so much when they heated up, I could never keep the valves lashed. Plus I changed the intake port on the iron heads a bit.
So maybe a Corvette with iron heads instead of aluminum would be even faster ??
That could really be scary....
