Haven't been posting much lately, but been reading alot and working on a 2150. Started out as a 2145 and put a 45mm 350 jug on. Base gasket delete, .018 off riser, .08 off band. Numbers are 105, 122, 76. Squish .018. Has the 359 carb and intake boot. Used the 350 intake elbow and mesh filter. I sanded inside of elbow to match carb. Advanced timing 1/4 key
On the riser I ground it out to match case then filled it in some with jb weld to get some volume back. I played around with this a good bit to get my clearances but good flow. I'm at a point where I'm not seeing much gains anymore. So I think I'm about as far as it will go with what I have. Some pics of the work.
