With a.528 MP solid, headers, recurved dist. and a 750 3310 Holley being the only mods, it did a [Email]13.50@104mph.[/Email] No traction and horrible 60ft. times. With slicks and decent springs it would've easily hit 12's. It was a torque monster on the street!
I had a low compression 440 in my GTX for a bit.
Stock heads, 509 cam, headers, TM7 intake with a TQ and a manual trans and it made several 12.6 passes on slicks without breaking a sweat.
I'd not worry about the shortblock too much. Pop in a better cam, find an aluminum intake like a Performer RPM or one of the DP4B? dual planes with a 750-850 cfm carb, headers mandatory and recurve the distributor and go have fun on pump swill gas.
