and the cam is....? RC315?
If it is a 315... measured IN/EX open/close at 0.04" and total lift?

Bill/BentON Racing · « **Reply #204 on:** January 21, 2016, 04:29:57 AM »

327 PeWe, good looking one, Bill

I think it says 327. Good deal Billy. How many 327s you got down there? Must be a record collection at this point...

OK 327...racing only.
I'm curious about measured 315 data. If overlap is not too much I'll try it on the street if I can get one.

Bill/BentON Racing · « **Reply #207 on:** January 21, 2016, 09:33:03 AM »

It'll work on the street....we build a few with 315's back in the day. If you are performance oriented. 295 next choice, hell the 327 can be ridden by knowledgeable riders on the street.

Personally speaking, some of us have a hard time with the 327 on the dragstrip.

Yeh right! You especially handle it much better than most!

+100 I loved mine too.
It was my experience the bigger cams really come to life with a higher CR piston, since the late closing intake valve doesn't allow the cylinder to build much pressure. Bigger bores with bigger domes cured that issue.

Lots of cylinder pressure makes them lots of fun.

Yah, going for all the cp I think dem 24 volts will turn! Bill

Nice parts you have there Bill. I'm anxious to see the numbers you'll put up on the scoreboard. After all this hard work you deserve to get great results. I'm behind you all the way. Time to really turn this scooter into a full tilt dragbike and show the world that the SOHC's aren't dead yet.

Thats an interesting hairline seam across the front of those... Looks like an old crack that was repaired? Too regular to be casting flash
