70 dart 470 ci drag car build.
I finally got a little more time although it cost 3 hours of not working, rough porting is really close to finished, I did all 8 runners by eye for now, next step find the biggest runner and copy it.
I'm very surprised I only busted through in 1 spot lol. I have ground through just about all of weiands runner aluminum. It's getting pretty big in there.
Picture of my junky looking short block while degreeing the cam, I'm trying to get a gear drive as this chain is stretched more than I expected after 20 Dyno pulls.
Lastly here is the cam card for the solid roller.
I run 1.6 rockers so it should be .680ish lift with lash .
Thanks for looking.
