9/25: Tony (Garmey) was my co-driver at the SOVREN Fall Finale enduro last weekend and he was very impressed with the motor. In fact, it pretty much rained both Sat and Sun. and I qualified second at Saturday's qualifying race. My best ever and I credit a lot to the broad torque band of your cam. Sunday was wet all day and I finished 3rd, 2nd and 3rd. I believe Jeff Quick has your cam from the motor he bought out of Illinois. In the race I finished 2nd, he won. Jeff raves about your cam, so you might want to check with him.
9/16: Racing this weekend at Pacific Raceways. Had a great outing in Portland at the Baxter Historics in July. The old girl ran every lap of every race. Even took a sixth in the last race! The Larry Young (298Dx) cam is spectacular. Lots of torque, much less shifting and a much more relaxed drive than the XXX cam. The latter cam would be great in a flying mile race with no curves!

For my part I run the 310 cam with stock lifters and have done 3 race events on that cam and about 2000 km road traffic. The engine power was greatly increased to 172 HP with a torque of 224 Nm. The cams torque band is from 3000 to 5500 while the peak power is at 6100 rpm. The last inspection showed all lifters and lobes in perfect condition. I’m really thinking about getting another one for my spare engine I will build after the season.

We think the Larry Young camshaft brought life to our engine in our preferred RPM range, that it has never seen before. We have another on order.

I did over 3 hours of track time at the weekend and the car performed faultlessly – the wide power band means that you never feel you have the wrong gear.
After two split liners, a badly distorted one, collapsed pistons, and chasing a high speed miss for a year; the car is finally running great. The high speed miss seems to be gone. As a check, I ran it to 7,000 and it pulled very well. The power is better than ever before. Several times I was on the starting line with Fred Crowley and his big Healey. Before, he could always beat me to turn one, not any more. I ran a 1:34.3 in the first two races. That’s almost two seconds off my best time, and I believe it may be a lap record for CVAR class VB. If only we had been running this well at the FoT event in 2006, that time would have put us in 4th place in the All Triumph Race, ahead of all the TR4s and other TR3s. Oh, what could have been …..

Over the winter, I ended up with an engine rebuild and an OD rebuild. I installed an experimental camshaft designed by our own Larry Young, and struggled to find a crankshaft that was usable. ….. Larry’s cam is designed with the idea that we want maximum torque between 4000 and 6000 RPM since our engines don’t have the flow necessary to run high RPMs. It has aggressive ramps that require the stock lifter (not the GT-40 ones).
The Motrah qualifying race ended up being in the wet. ….. I ended up coming in 3rd behind a V-8 Morgan and Dave Jahamiak, I think. It was a glorious drive, feeling the tires AT THE LIMIT in the corners. The Kink was one of the slipperier corners. (!) I kept telling myself: brake early, don’t screw up, preserve the car.

Last year Tony's car always pulled away from me on the straights. He did not make any changes between last year and this year. This year I could pass him at will, always about 2/3 of the way down those long Road America Straights. It seems that the car has more torque and better acceleration. I was turning a higher speed at the end of all the straights by a couple hundred RPM. The Elva that I beat has always been faster than me but not this year. Tony had beaten my times by one or two seconds at every Road America race for the last two years. Tony has to rebuild his engine this year and he wants one of these cams.
The thing I notice most about the cam is that it is not at all peaky. With every other cam I have ever used, there comes a point at about 4000 rpm when suddenly everything starts working together and you get a boot in the back. Fun, actually. This cam, however, does not exhibit this peakiness. It is a smooth flow of power all the way from 3000 to as high as you want to wind it.
When I got my car sorted, I turned a faster time than either of those guys [Henry Frye or Tony Drews], admittedly by only .3 seconds. The point is, of course, that Henry didn't run off and hide. In fact we were the same speed. I infer from this and from side-by-side comparison of acceleration, etc that Henry does not have significantly more hp than me.
