Almost same combo. 383 with 3 73 gears and Accel Tri-Y headers and tuning

Thats very impressive I'm hoping we can do the same ETs we have the first performance intake and a holley hp efi system for tuning a worked 700r4 2700.stall vigilante 9.5 in billet pression convertor s60 dana rear with 3.54 gears.. car with driver is 3400 lbs think it will go mid to low 12s?

As long as the bottom end of your motor isn't ragged out and you can get good traction, absolutely. Although I have no experience with your heads. How do they flow compared to AFR 190s? My times were at Milan, MI, not sure what your elevation is.

motor is brand new 4 bolt main 383 fully forged stroker.. our heads flow 250 cfm 113s done by tpis. Traction shouldn't be an issue we installed all umi suspension relocated torque arm and a strange s60 dana going to run MT drag radials our DA is usually sea level to no more then 2000 ft hot humid days..

I think you should hit your goal. You have more cubes, slightly steeper gears, slightly higher stall converter (I had a Vigilante, think it was either 2200 or 2400 stall), and a lighter car than me. If what I read quickly about your intake is true, it flows better than a SR. Although your heads are slightly worse than the AFR 190's. I think you'll hit your goal once you work out any kinks.

Yeah I read lingenfelter used the lpe219 cam and 113 heads so I kinda copied that build with the exception of using the first performance intake over the SR very true working kinks out will be key...

You used the lpe219 cam right was it lopey at all or very Mild?

I'd be very happy with mid to low 12s

The LPE 219 loped a bit and sounded really good. Pretty mild. I went to an LS1 Trans Am and stuck a Thunder Racing TRex V.2 - 242/248 .608/.612 110lsa +2 in it from there. THAT loped a lot, sounded amazing, and drove surprisingly really well on the street.

If I remember right, yes on the 1.6 rockers

Sold the Trans Am for a 545 cid 69 Mustang Fastback, that was a money pit and went through engines. Finally got it running about 1.5 years ago, sold it, and bought a ~700 HP N/A 2015 Z/28. Gotta love a H/C/I/E LS7.

True but an LS makes it easier to attain and even more with far less effort.

Thank you 1.67s 1.65 was the 60fts she had to roll into the throttle if she tried to launch it hard the nittos wouldnt hold..

Also it's still shifting at the stock rpm we need to address that either she will need to manually shift 2nd to 3rd to hold it out a few hundred rpms I think that will help with the mph and ET a little
