And I recently mocked up mine specifically for that purpose- my valves would need to be simultaneously open .230" each. The cam profiles I've chosen (aiming for peak HP @ 9,000 RPM) won't come anywhere near colliding my valves. Yes, this will be a small engine (182 c.i. four-cylinder) with small valves (2.030", max.lift .650"). But even for an engine of, say, 600 c.i. with large valves (~2.400", ~1" lift), I have trouble picturing both valves being open (during overlap) that much (or maybe more on the KRE?).

Today, Jack, there are competition engines running with 1.250" of valve lift.
Approximately DOUBLE the lift of your .650 camshaft engine. Just saying.

Tried to see if I could get a set of RAV's billets from Elarson. I understand why they wouldnt sell.

Never heard of the company that Jack used so I missed the boat on that one or I would have been game.

I think Roland offer a billet cv1 after i purchased my cv-1's.

KRE wouldnt respond to two of my emails and I left a message to discuss their heads with no call back. I think this was option was the best possible option for me but they didnt respond

This thread is a prime example why I dont care to get on here anymore. Travis made the mistake of trying to compliment advances and it "seems" like some took offense they didnt get on the "list". Others just whine and moan.

For me to be competitive "I believe" Im getting my engine sorted out then switching to BBC. Much easier to get support and buy parts that have some data behind them.

jdw, read my #38 post, you will like it. A lot of people say/said the same thing as you about the emails and phone calls not returned, in many of passed threads.
I was at the PRI show and talked to the Head, Head Engineer at Edelbrock. He said the same thing to me when I was telling him how I wanted to change the exhaust ports design.
In my mind, if you want to make any Traditional type Pontiac head the most RACE efficient, you have to cut the exhaust ports flush to the side of the head, put a 2.400 intake valve and play with the intake runners and move some stuff around in the valve train. I am trying to do that with my heads but lots of R&D and cash.
So YES, why not just go to a BBC, order a 1,000 to 1,500hp plus motor, pick it up in most of the time, 1 month or less and not waist your time on this web site complaining.

It sounds like you need to deal with another engine builder.

And piss on a BBC!

.

I don't recall when we talked but if it was before we had run down the track with our heads, I didn't want anybody else stuck with them if they had hidden issues. In fact, we made a few subtle but important changes after we had them downtrack a few times.

I'm not interested in being in the head business but could arrange to have some made now on an "actual cost plus a set fee" basis. They have big chambers (149 cc) so they're really only good for limited applications (nitro with a flat piston or blown alcohol with a domed piston).

FWIW,

149cc - daaaaaamn - do you camp in there at night so you dont need a motorhome at the races -- :-)

I wasnt complaining, just offered facts on why its tough to move pontiac performance forward.

I agree on the exhaust port, hopefully I have good success with my pontiac in 2014 while Im working out the BBC build.

Whining and moaning, not bitching and crying. Get it straight...

I will still have a pontiac, but I will also have another car with a BBC.

I also sent you a PM to discuss a different option around that time. I think you declined because you couldnt get the cost down to a reasonable amount. I didnt know what that amount was so I didnt inquire anymore.

jdw, don't take it the wrong way.
I was not singling you out not at all, all us Pontiac guys complain, me included.
I want to go really fast at a fair/reasonable price. (is there such a thing in drag racing as a fair/reasonable price) ???

Thanks for the reminder. The first set of heads cost me over $14k to make (bare with seats and guides). We switched to another CNC machinist who did better work at lower cost. Jack's heads at $11k sounds about right.

Nitro wants low compression (6:1) and no shock waves, so there is no squish area. It's just a big smooth bowl.

Wow, I never new it was that low.

So is anyone going to tell us what the kre dragster did that was so great? Still haven't heard or seen it. Waiting.............

Quote by Travis Q:

The ones I mentioned have really thought outside the box and made actual design changes and improvements to the original Pontiac design....look at what Eric did with the nitro-specific V head. Look at what Mellott and the Kauffmans have done with the Warp6 head and billet block....tons and tons of great changes there!!

That's still not faster then Rodney and Travis TT 63 Tempest brick!

Like I said....what is so impressive? Aluminium block, and these great heads and its not as quick as 3 traditional headed cars..oh yeah..they all out weigh the dragster by 400+ lbs. Boy..that sure is impressive!

I don't think Jeff ran the Warp 6 heads on his dragster, just the Billet HP Heads.

I realize that. But for Travis and Rodney's turbo deal, I wouldn't expect to see them use more than an inch lift- which I doubt would create valve collisions in the KRE hemi head. Let's see if Travis will chime in...
