Mine is a 68 Valiant V100 2dr Sedan, full interior except front bench (one racing seat at the track instead), full weight (has got a roll bar and subframe connectors, too). Engine is a cast crank 408 with KB 356 hypers, around 10:1 with cnc´d procomps, ede Victor intake and the Sniper EFI, 248/248° hydraulic roller cam around .620" Lift, 113° LSA. It ran 11.38 in this condition…..but ran 11.40 before with a shelf cam (comp XR286HR-10), ede Performer rpm intake, 750 carb and Indy X-Heads.....so far no significant improvement to me. I suspect the cam, it seems not to like the LSA, so i´m going back to a shelf cam (Lunati Voodo 243/251° / .600" Lift, 110° LSA) to see if it´s faster. And i bought a "real" converter now, a PTC 8" made for my car…...definitely wanna get this 10.99 timeslip ;-)

I would think so too. When tuned properly, EFI "adds" more off idle and low end than you expect.

Case in point: I ran this giant M1 single with multiport on a 9:1 360 Magnum in my Duster.

When i installed a Comp XE274H cam [230 int./236 exh .520/.522] I was concerned it would be a dog off the line with the huge plenum, adapter and 950cfm throttle body since the Duster was Rocking 3:21 and 9" wide 28" tall tires. lol those worries ended quickly. Stone cold I could fire it up, back out of the driveway and lay a 20ft patch a 1/4 throttle. lol
