question for the smart guys

I'm not sure I qualify to respond here , but here goes:

The 87 THM GT will make T/SA .
@ 150 HP, I think it's a bit high...Ask Jim Wahl about that combo. It's 155 in the Cimarron, FWD but you get a .430 lift cam.
The TH125 is essentially a mini T200, so all the low drag tricks would apply.
You are limited with the final drive , but a really short drag radial would work fine ,as I can't see how traction would be an issue.
Cams are available..390/ 410 lift is what a lot of the 350 Chevies use.
You'll have to fab the headers. You used to be able to get S10 kit pieces.
I'd build a 7 " converter to get the rpm's up to make up for the gear ratio.
I think it would run the NHRA index without too much trouble
