I was just looking at these and don't really know much about them.. I just tried to call them, but I'm guessing they are already closed for the day.

How much are they and is anyone on here running them yet?

if max effort is the name of the game, ET canted valve and a sheet metal intake, make 900 rw on motor then spray it with 2 stages of 300 each... and get ready to go 7.xx

Will be using a Canfield head when I build mine. Don't know what part number, it's a 6 hole head. Will try to find model. My expert swears by them. Good luck.

waiting for the GMMP LSx 6 bolt head to be released,
i beleive i read somwhere that will have the ls7 intake port and bolt pattern,
and use the ls7 intake manifold. they are supposed to flow better than the ls7
heads.

Now your talking!!!But im kinda liking the world block.I need to get my car on a diet and i know the lsx is more heavy than the 6.0 iron,how much i don't know but like the aluminum world block.

Damn since when did Canfield have a LSX head on the market??

900 rwHP on motor would be pretty un-streetable, if at all possible to begin with.

ET canted valve heads and a sheet metal intake are on "Colonel's" 427. 15:1 cr and race gas, open headers....made somewhere in the neighborhood of 840 FWHP, about 715 RWHP.

Another 185 RWHP won't happen, where will it come from?????

colniel's motor is a 427.... build a 480 CI motor and I bet you see close to 100 more hp at least, I don't think 427 ci is enough to even come close to maxing those heads out.

o.k. maybe you won't get to 900 rw, but over 800 should be possible

So nobody knows anything about those All Pro Hurricane heads?? Would a set of ET 265's be enough to run on a big cube motor??

Read ET's website, with a similar intake port design, a 400c.i. Ford motor made 1055hp@9700rpms. Its a little high strung but they're awesome heads.

It depends on what you want out of them. The all-pro heads are available from a as cast bare head to a fully ported assembled head. They would be perfect for a solid roller, as the CNC versions flow doesn't nose over until way the hell up there.

As far as the 265's, they would be perfect for a street focused 454, that would still make killer power.

All of them would require a custom intake to really see their potential. The Wilson billet would be perfect for a max effort street motor IMO

Exactly where I was getting the 900 rwhp # from... if that head on a 400 ci motor could makethat power, with a 460 to 480 ci lsx I see no reason it couldn't do it, and probably at close to 1000 rpm less

Quickin

Yeah, but now we're getting into pure race gas, probably solid roller, $10,000 valve train, and massive compression. Like I said, unstreetable for all practical purposes.

We're all talking about daily driver LSx's. Not pure drag engines that get rebuilt every couple months.

I think 700-750 RWHP is all we're gonna see for a true daily driver. And thats gonna be EXPENSIVE AS HELL.

And that 400ci Ford is about 840 RWHP. Which would be nice if it was a daily drivable engine.

If you're looking to daily drive 700 hp, n/a isn't the way to go about that I can promise you.... I'm making about 630 at the crank now and there's noone I know that would want to drive it daily that's for sure. It's a blast to drive, but the 9 mpg would drive you broke, 700 n/a is gonna get about 6 mpg maybe.

Does the block accept traditional SBC/BBC mounts as well as LSx mounts as was discussed during R&D?

427

iTrader: (3)

It only has the LS 4 bolt pattern.

Wait a minute, wait a minute..........

When my 436 was new it had almost 630 crank HP. It dynoed around 488 RWHP, than later 492 RWHP, than after I gutted my cats I'm sure it was close if not at 500 RWHP. Whatever, thats all splitting hairs.
Point is: It's a PERFECT daily driver, idle's close to stock, and has been my daily driver for 9 years, the last 5 years with my 436 stroker. It did 24-27 mpg HWY and about 15-17 mpg in the city (230-260 per tank depending on how I drove it)..........as a 436 stroker.

We will be seeing NORMALLY ASPIRATED 650-700 RWHP cars soon, and in about 8-12 months they will be common place, just like everything else.

My 436 is coming out very soon, like a month, a 454ci LSX is getting built and replacing it.

IT WILL have 650 RWHP, maybe more. And it's not gonna only get 6 mpg, thats a pathetic piece of **** engine that had its place back in the 1960's. I don't know who's building your pieces of ****, but 6 mpg is Pro-Stock 6 second cars. My car WILL get very good mileage for what it is.

First off, eastside built my motor, their rep. speaks for itself. 2nd, if you are putting a motor like what you are talking about in a car with a 4ljunkie transmission, be ready to put a tranny in the car every week... no 4ljunkie is gonna take that power and survive, it's th400 or glide time, or a 4l80 at a minimum..... but I figure you already know that.. and should be planning accordignly
Having 700 rwhp thru a driveline like a motor like that should have, will get 6 maybe 8 mpg, and I question if that power level can be reached with pump gas, it's gonna take some compression to get to 700 rw on motor thru a th400/glide.

I'd like to see you get the mileage you are stating thru a th400/5000+ converter..... that's not gonna happen.
