I'm switching out the current distributor for the good ol msd pro billet. The first time i did this 5 years ago (when i just bought the car and was new to motors) was with an original points style distributor. It just wouldn't budge. I ended up bring it to a shop. I was wondering if there are any pointers you guys can give me on pulling it out and setting it back in properly. The MSD manual mentions turing the oil pump shaft to make everything seat nicely, do i have to remove the oil pan for that or can i just crank the crank over slowly? Any info guys. thanx.
