Going for 1500rwhp and you are asking if you should use 4 or 6 bolt heads?

A2A and 1500rwhp don't mix. A2W is a different story. This a race car strictly?

I'm thinking going methanol for the reason of intercooler and being car is going be race car only

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.

There are two ODR guy on here right now that have run the LSX block and they seem to be doing just fine and have been for some time now. A few seasons at least. they have both been 200+MPH

I've seen a couple filled ls2 blocks push over 1500 HP.

LSX is a good choice for 1500hp, worked great for us to 1900hp.

We run a Warhawk now at 2500hp or so.

I personally would go water to air. The being fuel injected you won't get the real cooling effect of methanol like you do in a carb setup.

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 know if you can argue with this 374 inch LSX we did for Bob..

^^^didn't he use to run an older grand sport? or is that the same car?

Bazman

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.

You would spend a extra 8 grand on a billet block

I like ERL Resleeved 6bolt setup Ohio boys have 2 cars in 6s with those block and lots more in the 7s, LSX Block are strong and of course great price , If the price is not an issue RHS.

Bazman

They're not that much on top of an LSX but yes, as I hate to worry about stuff breaking.

No wonder my ex used to get pissed. If I'm in for a dime, I'm in for a dollar

DEFYANT

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.

Bazman

Surprised at the RHS, but good to know. Proline are good people.

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.

DEFYANT

Personally, unless you're shooting for 3000HP I would do an ERL build. The Dart Billet or LSM Billet are awesome pieces, but overkill for 1500HP IMHO.
