congrats on the fire, and it looks like you have a more than willing canidate for the swap!!
about the hp, I too am in the process of doing an lm7 swapped car. I am hoping to get around (more likely a little under) 400whp.
I have a torqV2 cam, worked heads, long tubes, ls6 intake, and a t56. With the zo6 cam, and full exhaust, I'm bench racing you at around 320whp. GL either way man!

Here is an article that I found that is encouraging on the potential of the 5.3

I have a lm7, z06 cam, ls1 intake and straight pipe on my e30 bmw swap. I put down 256/260 on a dynojet n/a, and 373/430 on a 100shot.
The stock truck intake flows just as good as the ls6 intake. If you put on the ls1 like i did, cause it was dirt *** cheap and needed it to fit under my hood, plus i was spraying anyways and didnt care... You'll be losing some power, and the cam will pick it up basically being a wash on hp gains.
You'll need FI, spray, or a monster cam to make near 400whp with the 5.3.

might be a dumb question, but what do you do about running coolant? i love the idea of being able to start the motor before putting it in the car but i'd hate to nuke a motor that was just put back together

Nice! I have a weakspot for a 77-78 TA. the Blue is beautiful.
I put a lm7 in a 62 bel air a while back, it made 267RWHP through the 4l60 and 20in wheels. It has a similar setup to yours, ls1 intake and a 218/228 .550 112 cam. I found out recently that I needed to go with 7.45 pushrods because of the regrind cam( I failed to use my pushrod length checker, too much going on) so it may make a little more power. Hasnt hurt anything but i'm losing lift and geometry. If your looking for 400 crank HP its doable, but prob not on a small cam. Just throw some hose at it...!
