Car- 1974 Duster
Engine- Fresh '94 5.9 magnum with Enginequest heads from Hughes with 1.92/1.62 valves, Crane Compucam 2020 roller cam with 1.7 roller rockers (460/480 lift) windage tray, Performer RPM intake with 625 cfm AFB. 318 exhaust manifolds with original head pipes that open to a 2.5" system with H pipe.
Trans- 904 reworked with extra clutches and valve body, stock 318 converter.
Rear- 8.25 with 3.55's and a locker, 26" x 10" M&H Racemaster slicks, Mancin Racing XHD springs.
I'm predicting well into the 13's with the 318 exhaust manifolds being the weak point in the package, 340 manifolds with 2.5" headpipes this winter.
I ran 13.80's with a 318 (stock 318 heads and 455 lift cam) and a stick a long time ago, with the bigger engine and better heads 13's should be a no brainer but the 318 had headers..
If I get a good hard launch I'm thinking it will dip into the 12's, what say you?
I run 12.5/12.6s with mine, i run headers & 3.73s with 27" MT Radials, adversage 60ft. is 1.81, best of a 1.79 so far. Its hard to say with those corked up manifolds, they will be the limiting factory, you really need headers, so i'll say right around 13.0s @ 100, could see 12.9s, most likely low 13s., also depends how much the car weighs with you in it.
BTW, your engine is fresh, so did you use FTs or factory style dished, i'm running on a junkyard short block & RHS heads.
