Looks like it is coming along nicely. How much boost are you planning to run on this setup?

well, I had good luck with E85 on the ford motor so it's either going to be that or i'll stick with pump 93 and my meth kit. Either way i'm shooting more for a performance goal than a boost goal. So whatever boost level gets me to 150mph in the 1/4 will be the magic number

couldnt use the factory fox body cross member,modify it like you would for a glide.
glide and 4l80 sit in the same location and also if the cross member has ever been modded for the c-4 its even easier.

mred- not even close. the motor is set back and the 4L80 is considerably longer than the AODE that was in it. The new trans mount is about 6-8 inches farther back

but whats the point? the factory x-member would have to be sectioned and stretched back to the point it would sag over time. i actually had the member sectioned about 2" when i put the aode in the car. not so much because of the set back but the pan clearance was an issue, so to go even farther with it would be harder than building from scratch.

here is the DP routing on the pass side snaking thru the k-member. going with coil overs really frees up a ton of space.

Curious. You want to go 150 w/ a stock internal engine?

Twin 70s is good for upwards of around 1000 hp or so if I am not mistaken. A stock internal engine isnt usualy recomended above 600 it seams. One t70 by its self can do that.

No, i'm going to take it easy on the stock internals. Just want to get everything done and working on the stock motor. My stock bottom end 5.0 motor went mid 10's @ 134 so i'm expecting atleast high 9's around 140 for now. I'll most likely do rods and pistons before i'll need a parachute

BTW, is that a photoshop 6.0 badge in your avatar?

nice. I was going to stick with the single T70 i was running on my 302 but i felt like it would hold me back. So i figured WTF and added another one. I think a single MP T70 can make about 700hp, but with my small exhaust housings i feel they'll support about 1200hp max between them. Gives me room to grow
