Im not doubting Tony's ability to do anything.. I am however doubting your ability to answer my question. I never said your engine would come apart, I said that your valve train would not live at high rpm. So is it an "1 or more offset and would u feel comfortable with 10k rpm on that valve train? Also, what tunnel ports besides yours have the push rod outside the port?

I never said this setup would work at 10k rpm. I said 10k rpm could be attainable with moving things around on a SMALL ci motor. I assumed you would know that csa could be played with and a smaller port designed, thus less offset, cam lobes moved, lifter bores moved, etc. An unrelated question, besides talking in circles, and a legit one.... how come your flopper ran 1/2 second slower in your possession than it does now with a less aero body?

two last points.. you have an impressive combo that nobody denies! i wish you the best with it. Also, the main issue on the tunnel port testing was not the valve train.. pro stock program was scrapped due to other issues with the head design and high rpm delivery. Carry on...:-)

Scott, what head what that now? a Pontiac, Ford, Chevy, Mopar? Still waiting on your inside privy on those tests.... carry on...

Scott, I could not find any info on anyone other than Steinbreck using a tunnel port head for Prostock. I did find some info on a 351 Ford with what they called a split port tunnel port design head. Kind of like what I have done with my heads. The guy claims it made 1023 HP. I could not find much more about it, except he claims it was outlawed because it gave the Ford boys an unfair advantage in Nascar. The heads were actually a Ford part in their motorsports catalog as recently as 1996. I know Tom V made mention of them, but other than that I could not find anything else about them. Does anyone know who the guy was that worked on this program for Junior Johnson? If so, I would love to get the guys number or email.

Morgan may have to eat that estimate of 2.25. The man is not infallible, we are not quoting bible verses.

And your comment now coming from someone who insisted the pushrod be removed from the port.. There's faith for ya.. LMAO

Morgan didn't like the port because of the pushrod in the middle. I bet he would reconsider the 2.25 figure with it out of the port. Also we don't know what the old tunnel port casting they were working with looked like either. It may have been a pos. Lynns and Dons heads especially have potential to up the bar further than any inline head out there. Pro stock level? No, but I am talking 2.3 per cube not the 2.7 it seemed to have grown to.

I forgot to mention. If it is indeed true, which I am not saying it is. That engine made 2.91 HP per cube!!!!!

Don, it would be nice to have one of those heads to see what the mindset was at the time.

JC, It looks like to me that they made two ports that share one intake valve. That was exactly what I had in mind when I did my port design, but I did not connect the center or the ports together. After I did some flow testing. Having a solid wall did not make the port flow any better. So my thought was that without it we could gain back some port volume without hurting torque. I think that if my port design works out that the problem with pushrod geometry will be almost non existent.

Don,
My memory is not what it used to be. But I believe that NHRA 500 ci Pro Stock engines at that time ('96) were well under 1300 HP which is 2.6 Hp per ci. Stan

We should all get along with one another and focus on bashing on chevy,mopar and ford and help each other out instead of comparing engine combos.We are all brothers here and we need to focus on making Pontiac even greater!!!! Great job on that bad ass combo J.C. and i can assure you all that J.C. can build any engine combination at any rpm desired what it all comes down to is $$$$$$ Im not choosing sides here i have respect for everyone on the py

Your probably right Stan. I don't think that the head I'm referring to was used in Prostock, but Nascar.

Pont428, What are the spec's on your build if you don't mind me asking? I don't know if we have ever met before. Were are you located?
