RHS or billet. Forget LSX. I would never consider cast iron at 1500rwhp, it's just not a good idea. One bad tune day and it'll be "poof!" and unrepairable. Alloy is the only way to go when you get that serious. Yes you'll give up 25hp (not on a billet tho), but it'll last and be repairable... do you think you could miss 25hp? If you can stretch for a billet you'll give up 0hp and have a FAR stronger and better race block. Bring an LSX to Pro Mod and watch them laugh. As for billet - LSM would be my choice, for lifters too, they're top shelf and those who know, win.

The setup your describing is pretty close to what I have currently (build in my sig).
Straight Methanol gets my vote, but I may be a little bias. I can tell you, I dont miss getting all that ice, hauling it around or the 240lbs off the car I lost when the W2A system went bye bye.
There have been some do testing on the cooling effect of methanol on a traditional EFI setup and have found at full boost over a 200*F reduction in IAT from TB to the intake valve. My intake was cool to the touch after the pass and that was only 12psi. Small amounts of up stream injection will add even more cooling if desired (many higher HP cars do this).
I know its different, but our Blown Methanol BBC would have frost on the hat after a pass. Crazy stuff. Either way good luck.

I don't doubt the LSX can, has, and is doing the job. I'd just personally spend the extra for billet by 1500rwhp in a dedicated race car, that's around 1800hp at the motor. In my experience once you can sort out and pedal 1500rwhp you'll want 2000 and then more.

The top of the line would be a billet LSM or Dart Block, followed by a Dart Cast Iron, then the ERL, then the LSX, guys have cracked the RHS block... Proline uses the LSX block for that reason.

LSM def tops, they've been proven in desert racing and spent the time to get even cooling between cylinders, the only billet that could boast that.
