a small overbore like .050 over is just to remove all the scratches, pits, and scars to get a clean surface on the cylinder wall so the rings seal up correctly. Usually the biggest overbore you can get without resleeving only adds less than 20cc, not really enough to feel a power gain. A BIG BORE requires boring out the jug itself and resleeving, which is a big enough difference to increase power output. Big bores can add up to 50cc's to a motor, maybe more on some.

You didn't read my last post close enough. I said a SMALL OVERBORE isn't intended for power gains. That only adds a few cc's. Your blaster has a 240 BIG BORE, which is designed to add power to the machine. I doubt you're getting 30 more horsepower out of that blaster though. I've raced a 240 blaster and only lost by a couple quad lengths on a 1/8 mile strip.

That's about what I was thinking. A stock blaster makes about 18 horsepower, how can 40 cc's extra add 30 horsepower? Even with his pipe and reeds I don't see that thing putting out more than 35 horsepower total. I know the one I raced barely had any more power than my warrior. I think most of it involved the 100 pounds weight difference. If it was a 1/4 mile track I would have won easily. I think that just with my edelbrock and opened up airbox i might even be able to take him on the 1/8th now.
