At 450hp the pontiac is gonna be the fastest street motor; most torque. My 78' XX block left little to be desired from a 400 block.

Whats the LS going for now? The LS was gonna cost me alot, I considered it, but stayed with pontiac for my firebird. I really liked what I saw in the LS series engine desighns, but it was gonna be a few grand just to get one before all the machine work and aftermarket parts. Consider that; other than an iron truck block, an newer V8 Camaro, V8 Firebird, GTO, or Vette had to be a donor, or it had to be new. The quotes where at 3k or so before work. For that I got a '70 400+.030 with Milodon 4-bolts, eagle rods, KB fordged pistons, and all ARP bolts, and balanced for about 2k or so + all I had alll the original pontiac stuff already in my car.

The LT1 woulda been a good choice for me to; I was interested in winding it out for road courses. They're good for high revs and cheaper parts. Didn't quite have all the virtues to make me want to put a chevy between the fenders of my 'bird.

I chose to stay pontiac. Up to you really. Let me know what you find out.
