70 duster project
Got my quarter panel last week. Finally got to the machine shop last night. Things were looking up. We started honing the number one cylinder to see how bad it was. About five thousands over the original 30 over bore. decided we should bore it to 40. Got it on the boring bar and his machine didn’t match up to the machine that originally bored it. Would have had to go with 60 over to be able to use that. Didn’t really want to max it out just yet. So I think we’re going to put some different stones in and hone it to 40 over. Sometimes I’m really glad (I know a guy) comes in handy. I know you guys really like pictures I didn’t take any. It was late and we didn’t actually accomplish much. As far as the heads go. Not a big deal to cut in the 202 valves and bowls and clean them up. But the double springs I got for the new cam won’t fit over the valve seals. So more machining, but the retainers they sent me for them aren’t going to work, they almost seem like there for a bigger valve. So I’m going to try to send them back and look for a single spring that can handl the 500 plus lift with the right retainers and some keepers for the single grove valves. It was pretty interesting when we looked up seat hight, and valve length in his books. The 2.02 valve wasn’t even listed for the 340. More trials and tribulations, but hope to get some more progress soon
