Brick,
can't really help you with the 109 question, but I did talk to someone who built a destroked S2. By going to a 222 from a 274 he was able to pick up 1500-2000 rpm. This did take the powerband up higher, but when all was said and done he said that he was able to produce about 75 more hp over a broader rpm band. So, lets say at 5000 rpm he was pushing 1000 hp, with the destroked engine he was able to push about 1050-1075 at 5000 rpm, but that he was also able to push that on to 7000-7500 rpm whereas the 274 was done by 6000-6500. The problem is that it wouldn't be too much fun on the street. Probably be a highway bruiser though!

You just may see a few destroked 109s or 4.1s next year in tsm.

OT, I know, but I thought Gallina destroked his motor to exploit the rules and Fruchey did the same thing before him???

6pack you don't have it all right . The reason they can make soo much power is they run stage 2 heads that are huge and flow 350 cfm on the intake. I know a few members that turn there 274 7500 rpm so there not done at 6500. The small cube motors make about the same hp with less torque and can run lighter weight break in class competition. 109 motors are cylinder head limited(stock iron heads), destroke might be a good idea !
