And last year your fastest pass with the big motor was 8.22 with less weight and forward scoop , correct?

Last year 2012? Made 13 passes, 7 were 1/8 mile. Motor was hurt when it came off of the dyno. If you look at any video it smoked all the way down the track but it wasnt oil, it was water. Broke converter first weekend out but went 8.26 @ 167 weighing 3055 in 3000' of air banging the 9k rpm chip at 1000'. Broke 2 transmissions testing and the head gaskets finally stopped holding water. I never made a pass under 2500' corrected last year.

Hey I get it, I have had nothing but issues the last few years to. My check book told me those issues had to wait.

JC's engine is within 20HP to 30HP of a conventional headed BBC on the first try. That is big news. They have already updated castings with improvements found in JC's engine. I spoke with them and there are already plans for JC and others to gain a ton more. There are huge parameters the keyboard crewchiefs have missed. Not surprizing.

My friend is building a forged crank 600 cubic inch braket engine. It will be interesting to see how much power that makes. There is also a max effort 406 & my almost 650 unless we can stroke it a bit more. Things are in the works that are definitely raising the bar. These guys follow the power as racers should.

update, another shaft is on order and going to do a couple of other tweaks. As soon as the weather breaks, be back on the dyno for a few more pulls. If everything goes well, we think there is some power to be had.

I'd try a 275 deg @ .050" intake with a 330 deg @ .050" exhaust. Both at the max lift your springs will manage (assuming 1.013") on a 120 deg lobe sep angle.

Holy duration... 55* split?

Aaron,
I would add something but I told Lynn I would not say anything about what he sent me.

Saw a 32 degree split on a Blower Ford one time. Never a 55 degree split. Interesting

Nope. But comments like that explain why you pay someone else to develop your combos.

You better watch out, that killer set of heads might come back running with a similar stick.

Now get that thing running 7.70's.

What car will have a motor you did running at Norwalk!

7.70s LOL!

[cgeise]

I know a lot of guys runing canted valve BBC and never seen that much split -- The throttle stop racers my run short intake like that but nowhere near as much exh. and I am assuming your talking about .050 numbers for both.

[Aaron Quinton]

It's too early to tell yet but likely the same as you, none.

So since you must know tons about cam timing and head development, why don't you try making an alternative suggestion and explain why instead of bashing others presenting ideas. I thought this board was here to help move Pontiacs forward.

Yes on .050" numbers with very aggressive acceleration rates.

What Bore spacing are they running and what size exhaust valve can they fit?

Stan

[Aaron Quinton]

Now that is the right question Stan. Bigger than a Pontiac.
