Going from 1,300hp to roughly 1,700hp. If you want to move air, Jeff's definitely got it dialed in.

1300 to 1700 is a big step up in motor and chassis.

Good luck in 2015!

This sounds like a very sensible alternative, I must look into this, it's their product, so who would know it better than them?

Lots! But it all depends on what you're looking for.

Its not about knowing the head, its about knowing what you're doing and knowing how an engine and induction system works.

This makes sense. You wouldn't go to Edelbrock for the best set of ported eheads.

I guess it does to some people.



Edelbrock isn't in the head porting business, they're in it for the money mainly.
(and not a Pontiac only company)



KRE is in the business of making Pontiac power.

When we first built the 526 engine (4.315 bore / 4.5 stroke) with the HP heads we did two intake manifolds for it. A Victor intake and a BOP intake. On the first dyno session we tested both intakes and found the BOP intake made about 8-10 more horsepower. The Victor intake made peak power at 7000 rpm and with the BOP intake peak power was at 7300/7400 rpm. With the little hp differance we use the Victor intake rather than at a higher rpm with the BOP intake. Now that said it is a nitrous only set up and we have only gone to the expense of setting up the fogger system for the Victor intake. If we were to do so for the BOP intake it might be a differant situation, but we have never done so.

We found 30+hp with our Victor at 8000 vs the BOP.

Glad to see you are doing better....is that the BOP I bought from you? Your memory was foggy then on numbers. Your alltimers must be in remission. Seriously, how can you compare a BOP and victor on a smaller motor app.? Sounds like a miss match of parts? A BOP is clearly optimized for a bigger cube motor.

Sorry for the derail on the topic,...raining here too and catching up on as the Pontiac earth spins....

Hey, I did flow a early Kauffman cnc 400 cfm port on Meaux's sf 600. The port did right at 400 peak, which is pretty darn close to what Kauffman advertised.

If I may ask, at what lift did they reach this number?

Meaux quit flowing at .950 lift on a 4.35 bore and they did mid 380s at the same lift on a 4.28 bore. These were some of the first batch of cnc heads they sold years ago.

They probably have improved their cnc program by now.

Are you wanting a class motor head or best bang for the buc job? Hand porting involves digging deeper in the pocketbook as a general rule.

I don't carry the dyno sheets around with me. I told you the Victor did better.

This transaction went on for some time. Loose your sheets? 30 hp would be a number I could remember....and evidently you did at this point. lol
