I took my Torino down to Memphis motorsports Tuesday night, it weighs 3930 w/ driver I ran a best of 13.39 @ 101.44 1.94 60' I used some dirt track tires for traction. my best time on street tires was 13.72 @ 100.23 2.23 60'. What can I do to improve, I want to get a 12.99.
This is what I have
.040 429 DOVE-C heads ported, dished pistons 9.5:1, shorty headers performer rpm Intake w/ 750 DP Harland sharp rollers
cam 218 @ .050 .509 lift runing timing at 34 total, 3k stall launching at 1800 C6 3.89 gears

It's already running pretty good for what it is. To get a LOT more out of it, you'll want to increase the compression, use more cam, and install a looser converter... and possibly swap in some 460 internals.

For NOW... Depending upon how loose the converter is, you may be able to pick up a bit with a little more camshaft... but I wouldn't go over 230 @ 0.050".

Of course a GOOD exhaust can never hurt anything. I hope you've got at least 2.5" tubing with MANDREL BENT tailpipes. It takes a big exhaust system to properly ventilate a big block. 3" wouldn't hurt anything.

Good Luck!

It has 2.5 from the headers out to the mufflers, the guy at the muffler shop ran 2 1/4 from the mufflers out(but thats another story. I have a 466 that will be a later project but for now I want to get the most from this motor, I will be looking into a bigger cam since I am starting work at Comp cams Monday.

weeeell...if we put the engine and tranny in my 81 stang coupe it would probably go 11.99


sorry lost my head for a sec


I think its pretty stout for a 2 ton monster
I mean you are running a 9.5 to 1 engine with a RV cam. It always amazes me how good some 429's run with the "smallblock" stroke(3.59) they have.

What do you guys thinks about cranking the rockers down 3/4 turn instead of 1/2 and running 36 total adv? would that help any? The motor seemed to have a little stumble around 5k in 3rd, im thinking the cam is running out. I got the best results shifting at 6k in 1st and about 5800 in 2nd.

If your times listed are with the exhaust hooked up your doing very well.My little 302 has the same size exhaust and picks up 2 tenths just by uncorking the headers!.I would be careful tightening down the lash,if your not getting any noises now I would leave it alone.That cam should be all done at 5000rpms.I would get better exhaust,maybe some long tube headers and a looser converter around 2500 stall speed.As for the timing try it one way or the other at the track and see what it likes best,remember your mph is the indicator of how much power your making not your ET.

I ran with full exhaust hooked up, had between 1/4 tank and empty. What do you mean by loose converter? the one I have now flashs at about 2900-3k and I can foot brake it to about 2300, I tryed launching at 2200 on the dirt tires and my 60' got worse like a 2.02. The best mph I got was w/ street tires and it was 102 ran a 13.86 w/ 2.44 60'

By a looser converter I just meant something that would let you get your rpms up to around 2500.Sorry I missed the part in your original post about you already having a 3000 stall converter.Now the problem, as you've already discovered,is to get the beast to hook.By dirt tires I'm assuming you mean McCreary's,These work pretty good but a set of ET streets or ET drags should let you come off the line much harder without any wheelspin this should get you closer to that 12.99
