What ET & MPH are..

340 Dart said

12.9@104 in a 75 Dart. The car was 3480 with me and 1/2 tank of gas.
Stock bottom end 360. MP480/280 cam, weiand Xcellerator intake,
Holly 600DP, MP 2600 stall convertor, windage tray, MP distributor, 1 5/8" Dynomax headers with magnaflow muffs with "X" pipe and 2 1/2" exhaust. The rear was an 8 1/4 sure grip with 4.10's and SS springs.

This would definately have run better with a decent convertor, RPM Airgap, more gear and a better carb.

This is what i would exspect them to run, hell my bolt-on 97 Z28 ran low 13s @ 102-103 & its a chevy lol, & it definitly weighs more then your run of the mill A body, a friend of mine bought this 71 Swinger with a 360/904 back about 5yrs. ago, it only had bolt-ons, stock converter, 750 3310, 3.91 gears & steel rims with 215/70/14s all around, with traction problems it pulled off high 13s @ over 100 when i ran it, 60fts where sour too. I'm hopeing my 71 will pull off mid-lower 13s with traction with this 95 magnum & RHS heads/crosswind intake, my goal is 11s on the bottle, even if its an 11.99.
