Default 71 chevelle lq4 build

last weekend I bought a 71 chevelle, ive bee looking for the past 6 months for a decent chevelle. I found this one for a steal and have had a lot of offers from others to sell it. but ive seen a lot of people making a lot of power with these lq4 motors with a turbo. the chevelle is all original, almost everything will be replaced. the car is fairly solid, the only rust is a little above the rear wheel wells, a little about the passenger side tail light and a little on the driver side lower front fender. as far the exterior the only spot on the interior is the trunk pan. the plan for the car is a street/strip car that can make it into the low 10's. the plan for the motor will be an lq4 with a custom cam, S480 with batmowheel turbo, a set of 317 heads worked over, cant decide on intake. transmission will be a turbo 400 with transbrake, 12 bolt rear. Am I on the right track as far as a 10 second car? I have read a lot about these engines and everyone as there own opinion on what works. the purpose for this thread is to get a plan so I can get the right parts the first time around and not waste time and money.

Yes you can use the th400 or the 4l80e, the benefit is overdrive with the 80e . Also depends on what computer you use if you want to run the 80e get the original gm harness Redone if you wana use the th400 I recomend microsquirt fron efisource

will the 80e require having the trans tunnel modified? and as far as a turbo street/strip car which is going to be more reliable? this is all new to me, i use to be a diesel mechanic and built a sled pulling truck, i had a ls1 Camaro that i had i did a few things to nothing crazy. any help or advice i can get will be greatly appreciated, i have a little body work to do so im getting that done while i get a plan together. i want to get a parts list together so im not doing things twice. i want a car that can be driven on the street reliably but be a low 10 second car where its not to the point it will be where it is pushing the limits or turned all the way up. if that's possible, i want to build a stock bottom end lq4 and see where i can get with that and more then likely build a 370 done the road.
