4 classes around here:

IMCA LM rules Steel block, Brodix alum heads/intake, 390 carb

Limiteds Steel block, Bowtie steel heads, 11-1 comp, 4412 carb

Nascar Super LM's NO SB2's, 4150 carbs otherwise pretty open

Open touring LM's which include SB2's, they seem to be the popular choice

most guys here are running all aluminum engines 400-434cui, with either brodix or pro-action heads (14deg stuff). there are some 18deg and some 23 deg, as well as the odd steel block too (ours is a steel block). the sb2 thing hasn't really caught on here yet, i think most guys have so much invested in there current stuff, that it would be an extremely expensive project to convert to sb2. we've just purchased a set of sb2.2 for ourselves but it will be some time before we'll have that deal running.

At our track everyone runs a steel block with flat tops and a cubic inch limit.

The main difference in engines is in the heads. You can either run the SUPR stamped Brodix 11x aluminum head or run a cast iron Bowtie that you can port all you want.

On a heavy track I'm not so sure I'd want an aluminum block. I'd want the front end weight to help get the car through the corners.
