Yeah you are using what you have and it makes power,good for you,go ahead and advice the hole world to go for the less good option of the two just because your car runs good instead of the better option.yada yada yada on Quinch. My 408 with flat-top piston ran low 9.70's@2860 pounds in my Duster, 10.08@3200 pounds in my Sons Duster. Now they are on his stock crank flat-top pistons combo running 6.54@3200 pounds. That's around 10.30's or better in the 1/4. No tricks, no bells, and zero whistles. Ohhh and neither decks were cut on the blocks.
Im out im not beating this dead horse anymore.
