Wait a minute dude. Those times are 1/8 mi. If I went 7 seconds in the 1/4 mi I'd probably soil myself. According to the conversion chart I have, 8 flat in the 1/8 mi is the equivalent of about 12.5 in the 1/4 mi. Almost respectable but my goal is very low 12's all motor to stay out of roll bar territory. It is fully street legal right down to the egr valve and catalytic convertors. Then if I decide to strap on some hidden squeeze...... Anyway, Hot Rod magazine did a feature on a 383 with vortec heads and they slid a XE282HR in for 463 flywheel HP at 5600. It pulled 12 inches at idle but lost 25 lb-ft below 3500 due to the 110 LSA.
