Mike I know your motor well! Mikes motor was built after my first motor which than inspired Dan to do his. Then Mikes came next. Unfortunately mine lost a cam lobe. We went back to mine. With all the latest motors built in the last 3 seasons we learned a bit more. Each spent extensive time on the dyno.

Our new numbers for my latest motor were 403 hp and 530 tq. We really do feel we have reached the end of the rope as far as PS motors go.

On intersting item we have found on both the RA IV (2 dyno'd this way) and the HO (2 dyno'd this way) is that the T/A hood scoop on the dyno actually had them gaining power! We are not sure it has translated at the track but interesting none the less.

Dan and I dyno conseratively. It is somewhere between SAE Net and Gross. A bit closer to Net. We have pipes on the exhaust, fuel pump, water pump, alternator but unpluged, and air cleaner tested also.

The last motor we did was a L79 Corvette 327 we even tried NOS full exhaust, NOS side pipes, performance exhaust, performance side pipes and both size of exhuast manifolds for the L79. We even built adapters to test small manifold with large pipes.

We are doing our best to improve the breed as we can.

Lloyd I would go to the Pure Stock Muscle Car Drags in Stanton. It is the most amazing thing to see 150+ cars racing under these rules.

The Martin FAST race has its draw also. If you have never seen a car pull the front tires on bias ply's and run in the 10's it is amazing.

I just personally prefer the fall race at Stanton if I was going to do only one.
