We actually gave up a few peak numbers but increase the average a bunch. This is actually what I feel is our best pull even though it's down 3 hp.

Mike, what was the difference between the peak HP run and the better average one. Timing change?

We made a cam timing change.

There must be great satisfaction in being able to move the cam timing for improved (best) performance. Someday....HIS

The bop belt drive is the bomb. Very nice piece and easy to manipulate Cam timing to your satisfaction


Just make sure you have plenty of valve clearance for the changes you want to make

Better yet, move it while running. It's all boxed up now and stored away- straight-cut gears were too noisy for my resto-mod GMC. On the test stand it showed promise- cam advanced nine degrees (crank) below 4,000 RPM improved throttle response and greatly improved the idle of a very "lumpy" cam. Next time I build a V8 Pontiac I'll look at converting it to helical gears- if i can concoct a compact scheme for containing end-thrust of the idler gear.

Congrats Mike and all involved! I agree bad weather dyno day will show less power. But what I don't get is how you guys get into a dyno with dyno operator you trust,whenever you feel like it or when the weather is good. My experience is when my guy calls me To tell me what day his dyno is freed up I gota go no matter what the weather is or it could be months before he gets a open time to try it again ......anyway congrats hope your shoulder surgery doesn't keep ya down to long so you can get on the track soon!

While I will agree I am very fortunate to be taken extra serious buy some very competent folks in the automotive motor sports industry. I still have to deliver on my end. For example when someone is squeezing me into their Dyno schedule I need to be agreeable about which day works for them. And if it's raining that day then that's that. I would have loved to have dynode on Monday of this week. 40 water drains 37° 29.92 on the barometer. That there is horsepower air.

My Blower motor is sitting at the machine/dyno shop right now. I could have it dynoed any day I want. We watched the weather in the past and did it off the forecast. They have plenty of other engines they can put on the pump if I decide to wait and lots of those guys don't care about the air and use their time just to tune to peak HP/Torque and make sure the engine is broken in correctly.

I have decided not to dyno this one because it's just a street car engine and will see very little track action and I can spend the money toward something it needs much more...
