Cylinder head flow - What is crucial in a stocker?

Let me revise that to around 9.4 HP.

Stan I wouldn't argue anything about machine work with you, but I disagree on the HP needed. Maybe in a lightweight car. But in my 40 plus years of running stockers I'd say more like 15 to 18HP. The point I was going to make if someone can pick up .7 with an intake and heads you must have some pretty bad heads to begin with. Just a few years ago it was 8hp difference with an intake on a small block stocker. If someone is getting much more than that I would love to see it in tec at Indy.
Using the 15 hp number to go .7 you would need to pick up 105hp. That would be 97 hp from head minus the intake. I think I use one of the best out there but if you have someone that can get me 100 hp from a set of heads please let me know. BP

Barry,
I don't have time to optimize these simulations.


60 Foot ET = 1.3610
330 Foot ET = 4.0108
1/8 Mile ET = 6.3058
1/8 Mile MPH = 106.6345
1000 Foot ET = 8.2990
1/4 Mile ET = 9.9840
1/4 Mile MPH = 134.2295

60 Foot ET = 1.3746
330 Foot ET = 4.0519
1/8 Mile ET = 6.3693
1/8 Mile MPH = 105.5199
1000 Foot ET = 8.3839
1/4 Mile ET = 10.0866
1/4 Mile MPH = 132.8920


Race weight with driver 3375 #. 17 HP difference

Thanks Stan, it looks like you have a couple of my times slips. Excluding 60-foot times. And it was about 16hp difference. BP

Stan I just sold my business. I'm helping with the transition but I'm only working about 20 hrs. a week. Down from 10hrs a day 7days a week. I had 19 employees. What a weight off my shoulders. I'm 66 and feel I should've done it 2 years ago. Don't wait too late. Get out while we have our health. BP

Congrads Barry, since you are going to be commitment free, we look forward to seeing you at a lot of events this year putting a spanking on racers from near and far with that bad *** camaro!

Thanks Eric never thought I would sell it during Covid. Sold it for a little less than it was worth but glad to have it gone.
Most of my years racing I always had to leave late and take phone calls all day while away. Most of the time a friend or two would meet me at my house 6 at night to finish getting my car ready than to load everything and get on the road for midnight. Drive half of the night and hope someone saved me a spot. Get in in the morning and unload the car to rush to make the first time shot. It will be nice to be able to enjoy the races this year. BP

Sorry for any confusion. I originally put .07 but like someone said earlier in a post it's 7 tenths you pick up with heads and an intake. I do still stand by my statement if you pick up anywhere near 7 tenths from a good set of heads and intake you better stop going to the lawn mower shop for your machine work. BP Thanks Bill for catching it. Trying to do to many things at the same time.
