closer to 185 than 200. riley just says that because he dropped an arm and leg on a big bore and cant make over 175. I guess I would knock other sleds two.

That's the 2nd time it's been on ebay. Last time he ended auction early, I'd sure like to have that baby.

Well the big bore alone can put the engine out to 120. Add pipes, and depending on RPM that can put the engine out to 140. But, personally I think he's over estimating if he thinks at 9800 RPM he'll be making 200 HP or even 185. He needs about 10500 to 11000 RPM in my opinion. A little port matching and possibly some porting on the exhaust ports, and you could be talking 150-155. Now with some head work I think you end up talking 165 HP at the advertised RPM. Just my opinion, not like I haven't worked on them or anything.[;)]

I totally agree 150 to 155. It's hard to get more then that dependable hp out of the older piston port 650 motor. Madcow it will be running before Christmas. Riley

my older brother used to run an older 650 super stock. HTG motor. not sure what the big bore kit would add but i was pretty sure that his 650 was dynoed at 160-165?? hp. and if i remember right he had to run just over 10,000 rpm,s
