I picked up a clean set of used "706" casting heads today. I'm starting to acquire parts to put the aluminum 5.3 together as I'd rather not hurt this LS1 and shove it in something else N/A. These are the smaller chamber LS heads and have a slightly smaller intake valve, but from what I've seen on a small bore (4.8/5.3) these are up 20-30hp/tq across the board over other style heads. It'll end up being 10.4/10.5:1 compression

These LS engines seem to have a lot of versions of things that can be interchanged without going very far away from GM.  One of my favorite shows is Engine Masters and they had a show one night testing the various oil pumps and showing what power they could require.  I was shocked how many hp the big ones required and how much oil pressure they could maintain.

I had thought that the modern stuff would not need such serious stuff due to the ability to run tight clearances on light weight oils, but, I guess when one is pushing a 1000 hp, or more, that it takes a lot of effort to keep it from "rubbing".  Wish I could start over with the LS stuff.

The modular nature of the Gen3/4 LS engine pretty much makes them adult legos!
While I'm much older and wiser, I'm a believer - I've had my firebird for nearly 15 years and have pounded on it relentlessly - It just refuses to die.

Nice!  I got a couple of bars of lava soap which still works like a charm!  Also a Milwaukee 3/8s impact on which works really well, also.

I have heard that some leds were polarity sensitive but all that I have used seemed to work both ways

Some brands put a diode bridge in front of the LEDs ,many don't.
