M1 or Port-Matched LD4B on 408

@360duster Is you car full weight and interior?
Can you tell us about it some more. Cam size etc..
Thanks.

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 ;-)
