Those small block Chevy engines that Roger built was very impressive

Nice tool Charlie. Very simple and and nice explanation of what it is, how it works, and how it's made. Regards Greg

Hi Charlie. I have seen the tool before in David's porting book but that looks like a quick and easy way to make one. Thanks for sharing. Andrew

[@dondotterer24]

Thanks Charlie . I haven't built one yet but I should. I wish Roger was still around. I did have a calibration plate made that he come up with for my homemade flow bench. It converts the monometer readings to 28". Of course I'll have to use it on any day that I flow. something. Time consuming but I'm not gonna Use the flow bench as much as you do

I think I still have the article that Roger did porting some vortec heads .I think maybe DV improved on that maybe you have too but it was a really good article
