thanks- yes def need to nail this motor down.. Yep some horror stories re covid- wife and I are in the Lords hands, and have pretty ok health so hopefully we will be ok. Kind of glad to get it and get the antibodies, we arent super sold on the vacs..
and of course the shop stands still when im in bed!
so despite the mystery of the weird diagram i will do some tests when im back up and have time for it, have to refresh a 350, build a 383, replace cam on a 140, weld racks for parts, rebuild a suzuki 300 powerhead and its a daily struggle finding space on all the work tables :/
