Default heads, chambers

1951-58 Chrysler hemi head design

1954-58 Chrysler poly canted valve design

both went on the same block

I cc'd them- (also bought 4 hemi engines plus parts, heads, etc.)- the hemi big port intake ports are 175 cc's, the poly canted valves are 150 cc's- with only 331 CID, the 331 hemi had a larger intake port than a stock Pontiac 455 HO engine. The hemi was made for HP potential.

imagine being able to get this stuff, on a Pontiac, right from the factory. Chrysler had it back in 1951-58

we are 60 years behind them right now

Default poly canted valve

the polysphere canted valve engine, had an even more extreme pushrod angle than the hemi, but they managed to make it work on the same hemi block- they raised the cam and angled the lifter bore downward

the pushrod points almost at the exhaust port

this is the problem we run into, putting hemi and canted valve heads on a Pontiac, the deck on a Pontiac is smaller side to side, the valves can't be canted as much on a Pontiac without running into valvetrain geometry and interference problems- like with the M/T heads

a raised-cam Pontiac block with angled lifter bores like a Chrysler, would enable a more radical hemi/canted valve head design

it pays to crack a book once in a while and study, it saves a lot of money on pushrods and grinding stones... why try to re-invent the wheel

Zedo, why are you ruining this thread about the KRE Warp 6 head?
Hell, International Scouts had canted valve engines years ago but who cares.

Have you ever looked at a HEMI block? You will see where Chrysler cast in the clearance that needs to be cut into other blocks. Just set a 440 block next to a 426 HEMI block. It will jump up at you.

when the Pontiac inline valve wedge 287 CID came out in 1955, Chrysler already had the 331 Hemi and polysphere engines, and was dominating NASCAR with the Hemi

how 'bout a blown canted valve poly street rod

Default hami head

zedo why is it that every post you put up is always talking shit or trying to tear down what others do when it seems you dont do much yourself. you should stop being a keyboard warrior and spend more time with your car. have a good life being ignored

There's always a DB in the group. KRE is kicking butt on new development.... ABOVE ALL. Name any of the other big names that are developing new products like KRE has done.

yes, KRE had some nice heads, blocks and ran some fast cars- there may have been some quality issues with heads and blocks, but there is with any heads or blocks to different degrees.

The real issue is, in the realm of creating new cylinder head designs from scratch, how fast your race car is, doesn't mean anything at all. You have to be an engineer first.

John DeLorean created the GTO- he wasn't a bracket drag racer, that raced every weekend. He probably never even drove anything faster than a 13 second street car. Yet if he was still alive, and came on PY or PZ today, under a 'nym name, he'd be bashed by the trolls that litter these message boards- because he wasn't running a car. He'd be judged by paint job and timeslip, not his engineering skill.

That's what is messed up about this hobby. That mindset has to change to progress.

So the real question is, why did it take KRE, and all the other Pontiac engine builders/vendors, this long to realize that a hemi or canted head, is better ?

14 year old kids knew this back in 1975- Chrysler knew it in 1951, Chevy woke up in 1965, and Ford changed over in 1964-69.

until now, all the Pontiac vendors were making, selling, promoting inline valve heads- we had those pathetic aluminum D-port heads, which were a step backwards in technology compared to an E-head

Roland Racing did it first, and sold around 100 pairs of CV-1 heads, and cut into their market.

so now everyone else is going to play catch-up to a real engineer, who knows casting technology- not someone who is just a weekend amateur racer and chases one fast timeslip and tries to sell parts based on it.

there's a difference, and you're seeing it first hand.

what I see is, vendors who judge designs only on timeslips, and race the same car year after year, running around the same time, get all bogged down in their own combination like they have blinders on, and can't see the advantages of competing superior designs, until it's too late, and someone else sweeps the market out from under them

my next engine won't even be a Pontiac, it's going to be an early Chrysler Hemi in a Pontiac car, because I'm not bogged down by those limitations- why go through all the trouble to change a Pontiac, when you can just run another design ? At some point it becomes not cost effective. In other words, why make a Pontiac into a hemi- just run a real Hemi- it costs about 1/4 the price, and you don't have to whittle heads out of a block of aluminum. In the end what does it matter, if the "Pontiac" block has aftermarket block, heads, crank, rods, intake anyway- it's no more Pontiac than a Chrysler hemi is.

that may sound silly, but it's done all the time in engineering circles- example: the P-51 Mustang fighter plane became great, because they took the Rolls Royce Merlin Spitfire engine and put it in the Mustang- until then, the Mustang was a slug with it's original Allison engine. When they changed the engine to the Rolls Royce Merlin, it became a superstar.

Wow, whats this garbage.
Everyone has to play catch up to a real engineer?
Catch up to Rolland, they are in 4 freaking place behind the inline Tigers, High Ports, Edelbrock Wide Port and even the Edelbrock Std Port.
Those things have problems which is why they shrunk the port to give them room to fix the problem.
Oh, and the P-51 was not a slug with the Allison engine under 15,000 feet. Its problem was not the design of the engine per say. Its problem was it did not have a Super Charger. They never did put a super charger on that engine but they could have.
They did have turbo chargers on the Allison in the P-38s and is was a great fighter.
The P-51 was a bit over rated. It did do a great service by finally escorting the bombers all the way to Berlin and back which helped end the war sooner.
But the best fighter of the war was the Chance Vaught F4U4 Corsair. The one with the big 4 blade prop. Not many people know this but the only thing the Mustang could do better was range and a bit better vision. The Corsair could out run it in level flight, out climb it,out dive it and even turn inside it because of the huge wing surface.
The Corsair could carry a much bigger payload of bombs and rockets. It was also much tougher because it had no cooling system to shoot out. All it took was one bullet in the radiator of a Mustang to bring it down. F4Us made it home with a entire cylinder shot off. As long as it was not one on the bottom where all the oil would drain out.
They kept building them up until 1957, that tells you something.
BTW , I hear Mexico still has some P-47s in service. They ought to put them to use strafing the coke runners.

Been a while since I posted on this.We are getting cloce to dynoing our first warp 6 motor this build has taken longer than I expected as we are covered up in engine builds at this time.Seems like most everyone waits till this time of year to order a motor then wants it yesterday. Jeff just about has the sheet metal duel 4 manifold done. I had the valve job done on the heads several weeks ago. to day I did some checking on the cc's of the chamber and the intake and exhaust runners.This build is for a 535 ci motor we used the cast size runners on this build and small valves.chamber came in at 58cc.with the small valve setup probable will be a tad smaller with max size valves.Intake runner was 400cc and exhaust runner was 250cc. Should have some dyno numbers in the next few days.
