Test hits Carb'ed 408
Test hits Carb'ed 408 Broke 3 ribs a few weeks ago, so y buddy made some license runs last night at Cecil in my car.
Combo
408ci 4.030" x 4"
Mast LS3 Med Bore 6 bolt heads
Diamond Pistons
Race Proven Motorsports cam
L92/LS3 Victor Jr. w/ ProSystems 4150 Carb
GMPP Distributor cover w/ MSD 7531
Edelbrock Plate kit
NOS Launcher Progressive
Had to make the last 3 runs for license, first run was on nuts for a 10.13@138
2nd run on bottle, car spun on the hit, pedaled it, and went a 9.5X letting out before the 1000ft
3rd run we made some changes to the progressive. 8.731@145 letting off at the 1000ft. Racepak data showed it was hazing the tires through first gear. 1.396 60' 5.614@129 in the 1/8.
Pretty happy as the tune up was a "get the damn thing down the track" set up. Very conservative on timing, high nitrous fuel pressure, and only a 225hit.
