It's amazing what you find out on this site. I just installed my camshaft , and guess what ? it's a little tight. Just like you Cranky and Rusty , I've been around this stuff since I was 14 , and I'm 55 now. Rebuilt my first motor for my Dads MG 1100 4cyl when I was 14. I merely told him I thought I could do It , and he says have at it. He gave me the FSM . I read through it and did the job. Just paid someone to do the machine work. Ive been assembling my own engines , transmissions and diffs for many years , but I never heard of the camshaft bore trick. Ive got my old shaft , and thats exactly what I'm gonna do. One question though . How deep do ya cut the slots and are they at 90deg to the camshaft? On a side note. Started my paid Automotve career at age 17. Went to work for an independant Auto Parts Store as a delivery boy for $1.75 an hour in 1974. Worked my way up to counterman and eventually store manager. In the 80's the partners splitt up and divided among them thier stores . 4 at the time. The Guy I ended up with was 25 yrs my senior and was looking for an exit plan. He sold me 25% of the store I was managing at the time, and taught me all the administration stuff. I paid him some cash and all of my bonuses every month. After about 8 yrs I learned it all but he was takin most of the money. Time to make another deal. He sold me his 75% and took alot of the note back himself. I went on to open 2 more stores in the 90's. We were flyin high!!.In the late 90's my wife started having trouble with brain tumors and profits were being cut by Warehouse Dist selling our customer base, cutting all the legit Parts Stores Throats. I attracted a buyer In Carquest for our small store chain. I sold out to them in 2001.They paid me for everything in our buildings and took my managers. But the old guys taught me to buy the real estate wherever I could. I kept all the real estate and have long term leases with Carquest to this date. So Obama DONT TELL ME I DIDNT BUILD THAT. Been retired since age 44 nutzin around in our shop at home , doin some resto stuff and reg repairs every now and then. Gotta get this Chicken done soon though. Sorry for the rant. Thanks for the camshaft trick !!!
