Quote: Brett did you flow yours with a intake on and off also and what cc intake did you end up with thanks
I did flow it with the intake but was just a velocity check on the intake I did not record the flow numbers. I think it was down 8~10 CFM with intake and carb on. The intake port was 215cc last year. I had not looked at the flow numbers from last years engine for a long time as you can see the short turn still needed work port was going into flow separation.(still good port just could be better)Andy's ports are not bad for the time I have in them. I got 337cfm out of 2.08 valve and much smaller port this takes much more time to develop. Hey Andy this is cylinder #7 upper bearing shell worst rod bearing in the engine. I think it should be OK just had some dirt go through it.
