I had a stout 422 W5 motor. The new owner of that car has been low 9.60’s at 140 with it on S/S springs at 3220. I ran 9.80’s with it, he made a couple of upgrades( squeeze and camshaft) little less weight
Still think that 245cc raised port head has more potential. I know a guy on Moparts, David Dean has been 120 in the 1/8 with them
