i just saw that this evening we are getting ready to put on the mallory wires and we looking at the routing... funny you should mention that
with the two NA engines 3100v6 in the front and 90 toronado trofeo LN3 3800
both are rated at 160 Hp and all we did was port and polish the heads and up on em
we ran a best of 13.81 at 98.2mph with pretty consistent 1.90s 60' times at 4330lbs race weight
we are pretty sure we wouldve dropped a few more tenths if we had been launching with the rear engine at WOT and modulating the front throttle to the traction limits. As it was we had both throttles linked and were only launching with both at ~40% throttle

right now with the two stock L67'* we are looking for low 12'* and with a few mods 11'*

you think you know Tq steer?

with the 4t60e behind the front L67 still having the quad4 converter (higher stall for the 3100) when you get on it it stalls at nearly 4grand on a stock motor! (sure it'* got a 3.5...)

anyways our first joyride was with the rear at WOT and the front also, we launched hard and spun the fronts for a block THAT was Tq steer we left two nice stripes though lol

it launched much better with the rear at 100% and the front feathered in from ~40% up much less tq steer there! cant wait to get two 80e'* under it and see how equal length halfshafts help aleviate the Tq steer (not to mention a nice 3.71 gear in the rear and maybe a 3.48 or 3.11 for the front (leaning towards 3.4

i cant wait for the rear L67 to go in 'er

HAH. jees. you're planning on a SECOND L67? wow. So the LN3 just isn't movin it fast enough eh? Thats gonna be insane with two L67s... 480hp and 560 ft-lb trq stock.

on a 4300 lb car.

holy hell, that thing is going to MOVE.

then mod them to maybe 300 hp each...

600+ hp and probably 730+ trq total after that

wow. thats insanity.

I wonder what that thing would do with 2 l67s modded to around 450 hp each, but I'd kill to drive that thing now.
