HP Edelbrock ?

472 11.5:1  with custom solid roller cam .The heads listed below and no port work or valve work . I do not  know the cam specs as the owner is tight lipped about that . Vic intake , 1050 2 1/8" headers. So here is my question can or will these heads as cast or sold make 854 hp as claimed the owner ?

Also what is the most hp that has been made n/a in stock or as sold form with the above heads ?

Thanks !

850 horses with stock, unported Edelbrock heads??....hmmm, I highly doubt it. If it was 500+ cubic inches maybe, but a "little" 472 isn't going to cut it.
This is only MY opinion, of course.
But I'd think it would be hard to eclipse the 700 mark with these heads.
Did he say how much nitrous he's using??...LOL

I like the Edelbrock heads and they can make ok power . In the 600 range pretty easy with some basic porting and on a stroker .

854 i'm thinking was a very happy dyno

Box stock I just can't see it...unless it's not really a 472

I would think it needs to be in the mid 500ci to and some rubbing on them to see that kind of power NA

I don't see it with 11.5/1 compression.

Bruno's 562" made 850. http://www.460ford.com/forum/showthread.php?t=132902

^^^^^ Yes So what?

326/207 cfm come on really now.

I've had some ported ones make 750 horsepower very easily on a mild solid roller cammed 521, about 6200rpm or so which is cool for a fun bracket racing engine.

854HP 472 cubes and 11.5/1 207cfm exhaust flow just seems pretty high, I guess anything is possible.

Just an observational reference relative to the original question.

Ok these are out of the box no porting heads on a light race car ! 854 flywheel hp

I am just having a hard time rapping my ignorant mind mind around this.^^^^^^ !



So if this is the case a few more points of compression and some port work then 1000 hp would be attainable !

My Edelbrock equipped 460 with a 250-259 580-608 sft cam victor intake 1050 4150 carb c6 4.56 gears 3400 lbs will go 120 in the 1/4 10.86 I don't have an electric fan or water pump and 11.67 compression ratio .I have another short block again with a RM cam with more lift and duration to try out at some time .The edelbrocks are supposed to have one of the best ex ports available of the common heads .The intakes not so much.Looking at mine they are a lot of bumps from the head bolt boss .I think the potential is there and they are a quality piece .When I purchased them I removed a set of dooe-r from my 466.The dooe-r had the exhaust ported and both in and ex bowls polished .They had been milled how much I don't know .With the iron heads I ran a 12.25 with the edelbrocks 11.96 everything was the same except the heads .My opinion was first of all my iron heads weren't so bad and secondly three tenths for $2000 ?? I am thinking of having the edelbrocks ported by a professional and running Randys cam maybe a 10.50 is possible By the way enjoyed our conversation the other night Mr. Whitefield take care .Doug

I did something similar but not on a BBF and had pretty much the same result. Wish I would have added another point of compression when I switched to aluminum. I think the 60 or so lbs of weight loss helps e/t some also. Nothing wrong with cast iron if weight and octane are not major concerns.

Good talking with you as well. Did you ever get a tail shaft housing ? Whitefield

It seems these are a hard item to find .I will probably just keep the one I have .I would like to take some weight off my porky pig though (3400) I have a former coworker with two c6s maybe one of his is a long one .Good luck Mr. Whitefield.

In normal cases the HP you quoted the guy saying ain't happening. Out of the box heads, flat tops, and optimum camshaft, your looking at around 725 hp.

I made that HP (861) with a 557 15:1 compression, and heads flowing 50 cfm more than an out of the box Eddy.

And exhaust port flowing 40 cfm more.

Another build I remember was Bruno's he had Eddy's on it, and I think it was a 562 and made close to 850 hp , but they were ported and flowed more than my TFS Streets.

Uh no. It ain't happening. Unless as Randy stated, upper end build high rpm and trick pony sheeet. And I still don't see it doing it with 327 cfm .
