Indy heads can have way more potential than W2 heads. Way more.

Good to know, buddy,

Prolly just sentimentaly 'attached' to the 2's. Many of my old war storys and giant slaying were with the W2's

My Indy 360-2's that Brett ported flow 337 @ .650. I think they were based off the W-2 head.

I've been following this post for a while. Have to say that the new head better flow 330 and up out of the box or I personally wouldn't bother.
A STOCK Eagle head will flow 310 cfm with a stock valve!
I think the LA plaform is dead unless Fiat cast some blocks. I know Ritter has some blocks but from what i'm hearing they still have some problems.
Dollar for Dollar I believe the 5.7 hemi will product more power at a cheaper price than an R3.
KEEP in mind we are talking 750 and under HP. I'm NOT comparing W8 or W9.
The reason for my statements are the fact that 5.7 Hemi are cheap and plentiful. The heads flow tons and parts are available.

Just curious how much one of these engines would cost to run 9.60's in a 2800 pound car like mine. I have 7500 dollars in my R3 with a solid lifter cam engine.

Well I have half of your total cost just in the heads and intake on my W9.
Not saying it's the best way especially if you have parts already.Hence the reason I built my W9.
But if your starting from scratch I believe the hemi is the way to go.

Ask 340 Rick here on the board. His car goes 9.60's at 3100 pounds with the new hemi and mild compression around 11 to 1.

Don't even get me started on how much a competitive Super Stock engine costs and how few runs they get on them. I had a Friend in PA sell everything he owned and he moved to Florida. There he got hooked up helping a Super Stock team and they let him learn some of the secretes and hone is "grinding skills". And this was back when the cars were a lot slower than they are now.

I think the most expensive thing with the new hemi is initially getting it in the car, oil pan, headers, intake (EFI or carb are very expensive unless a stock one can get it done for you)... Heads can be had cheap as in $500 for used eagles that flow 330 CFM OOTB, stock rockers seem to take some abuse, blocks are good for anything most would do, stroker kits are only a tad more than a forged LA kit, cams are a simple re-grind away from big performance.

Once you get it in and running you can turn up the wick pretty easily/cheaply.

An off the shelf early 5.7 can be had around $1000-$2000 depdngin on seller and miles. Get the eagle top end (intake and heads) later for 12 to 1 compression that will run on pump gas and a cam regrind and the sky is the limit with a #2800lb ride. Just know going in you got to spend some $$$ to get it actually in and running.

I don't see how someone could replicate your engine for $7500 without far above average home porting and some un-realistic deal on an R3 block. Your at $6000 for pro ported heads and R3 then add rotating stuff, intake, machine work, valve train... for $1500?

I just don't like to advertise, that's all. I'm into what the F.A.S.T. guys are doing so that's the direction I want to go.

You have a photo of that Hemi before it went out?

Rob C: Craig has pretty much answered your question for me:

"It's more than weight. Aluminum dissipates heat at a far better rate than iron, allowing roughly a point more compression on the same octane. So it's weight and power/efficiency."

And, I'll add: when you have x number of dollars set aside for cylinder heads you just take all the advantages of aluminum.

Agreed, I have run aluminum for almost 2 decades now. It's just the complaint/rant like post of why don't they make aluminum heads look stock. IMO, a silly compliant. Not that I don't think it would be cool, it is just they after market probably won't do it just because we think it's cool.'The W2's will perform, looks stock to most eyes. But you have to want a iron head to do a iron headed engine.
