I like it. I have to work out the adapter porting for my setup. With the LT4 HPFP I have to run spacers to raise the manifold. I was going to make it a more permanent bond once I got the setup running and put down some numbers, then go back and refine the setup. I can say for sure, I don't need any more than I already have, it's just icing on the cake as it were. I plan to step down to a 4.0 pulley, bond the adapters to the manifold, then port match (or as close as possible) to the heads. I didn't plan on porting the snout, just running the 95-87 adapter with LT5 TB but after looking at your setup I might have to work that snout. And I love giving Katech my money, so that works out too.
Will be nice to have a before/after for those specific upgrades, too. I'd probably leave the 4.0 pulley for the dyno, just to see what/where gains are had without changing blower speed. And then get my next bump. Tuner says I have enough pump/injector for more boost... it's just not good enough until the LT4 hardware is whooped. LOL
