Tom @ 3V performance is great guy spoke with him about a copy of Chris U cam for a Ls engine. Tom said they could develop a Cam-lifter and pushrod combination with it being tested on the spintron. Good guy again and very informative.

Chris Uratchko is good peoples called and had a good talk with him. Said I (talked with Tom @ 3V) and was referring to the Ford 457 and if a Ls build could duplicate what the Ford did for Mr. Wilson who it was built for. Reply was Yea! I was getting all warm and fuzzy as the short block isn't that bad in cost as I listed what I thought of using.... but had to ask could I use Ls7 heads and which ones he'd recommend? None and they won't get you there. I said Chris you answered all my ?'s and I know what type we are talking about. Big area and high CFM. Good guy again.

Here's some more info for the smaller bore crowd. I thought Mast SRT heads were the only heads to use a big valve. Runners too big but you can never know too much.

RHS™ Pro Elite™ Big Bore LS7 cylinder head, CNC Ported bare casting
aluminum, 307cc intake runner, 69cc combustion chamber, 2.250" intake/1.615" exhaust valves

Bore Size: Mininum Bore Size 4.065"

Max effort ends up dictating splayed valve arrangement
Higher lift equals less shrouding. Even the new LT stuff is slightly tipped. General knows !!!!

This is the plan old Ls7 RHS heads with 307 cc runner that fits a 4.065 bore this is from RHS web site. I had copied this and saved it.....Deleted while cleaning downloads and my documents. The exhaust is the problem with Ls7 heads and a small bore not the intake. 800+ with a 435 Lq4 and Ls7 heads with stock valves.


That's from ER.

Figure to much shrouding for crying out LOUD.

Talked to Russ@FRH this morning about what I posted and said ....That's right: You pick the valve angle and the Port you want raised runners standard. $3200 to $3500 with Custom Valve covers.

Patron

Good guy sent me a PM and Said Do Not say my name ....I can Respect that! But told me about some heads to take a look at...Ls3 heads with Canted Valves about freaking time ......Now where's the Ls7 canted valve? LOL. But seriously it would be nice as the runners are raise compared to the Ls3. Figure they make more Ls3 stuff as the Ls7 was a limited bore and engine.

Super interested in what Frankenstein is doing with their program. The fact that what they are doing works with any manifold is mind blowing. Is there data out yet Patron to see what these things will support? At $3500 with covers, that’s a bargain...IF they work.

Greg is supposed to have another set of those CID heads ready for a 523ci tall deck LS pretty soon. It made 701whp already on pump gas with ported factory heads IIRC. Should be interesting to see what happens with the CID heads.

Patron

Che70velle: Russ didn't go into detail but what I've listed about the Raised Runner and have multiple Valve angles. I'm Assuming the Valve covers are Billet. I can say this Chris Frank has gotten over 400 cfm with Factory Ls3 heads with his Stage 3 program. I told Russ I'll be coming up his way after the 1st of the Year to have some minor work done. Hopefully!


KCS the thing that's getting me is there's Just so much stuff coming out you just can't keep up. Canted Valve Ls3 heads, CID heads,etc .....just makes it harder to pick one as you've got so many option. Great for us as the consumer.

Just looking around this mourning for contact info on Richard Maskin & Ben Mens of Dart machinery, both of whom which I've got there #'s.....Oh I'll find you! *WJ couldn't figure it out either he's not listed* But Fact... To ask about the Dart Iron Eagle SBC that you can offset the bore to a 4.50 bore spacing and if that could be done on a Lsx Next Iron block which can go to 4.220 bore. I'm thinking of Chris Uratchko and a 4.310 Bore. I'm trying..

Found this while looking around Dart has Ls7 heads and intake can't keep up with all the manufacturers who make Ls heads now. You have a lot of choices...

What is the real point of this thread? Besides Patron doing a LOT of talking to himself?

Patron

So I don't have to make new threads about all the new stuff I find and you haven't found. Bandwagon guy Stop hating did you know Dart Has Ls7 heads? If so your girly self would have said something. You have anything new besides what you typically post? I didn't think so. I've got 4 or 5 different new products that I would have to start or take up space. Could you go and find or list something new.....I don't think so you don't research just ride in the wagon waiting for something to come along.

G Atsma

If it was all about new products many here could use, I'm all for it! If YOU find new products, chances are many others have too. But they might not have much to say as the product(s) might not hold their interest. And YOU have products?? All I have seen is you describing OTHER people's products. So Dart has LS7 heads. Those here that might use them likely have heard of them.
And speaking of my "typical" posts, nearly ALL are in response to others in the way of answers to questions (usually pretty accurate) or are questions I might have pertaining to something here on the forum. I do plenty of research. I just don't feel it's my duty to tell the world about stuff most already know. This whole thread is about you indulging yourself by trying to tell us how much and who all you know.
And the Damon Dash quote? Pure BS. Jobs are for many useful people who have something to contribute to an organization that will compensate for that contribution. Many who work for themselves are doing so because they were so into themselves nobody would give them a job.
