I've suspended working on my rpu project until after Turkey Run , but I have been going over my 27, getting it ready for the 500 mile round trip drive. I have enough miles on the car that I switched to Mobil 1 synthetic, and as soon as I did my rpms at idle went from 1000 to 1200. Had to set the idle screws back down a little..........I guess because of less friction.
Then I changed the plugs, even though the old ones were fine. I was happy to see the old plugs were a nice tan color, which surprised me considering I am running about 1200 cfms on a 331 CI motor. I am way over carbed, but the motor seems to like it that way.
Also changed the cap and rotor. I didn't realize it when I bought it, but I somehow ordered a Mallory Unilite distributor that is made for drag racing use only. I was wondering why the center button on caps wears out pretty fast so I called Mallory to complain. The guy told me that this distributor has that problem because it is only designed to go 1/4 mile at a time and they made the button to make better contact and transfer higher voltage without arcing. So once a year I replace the cap ($50
) and I am good for another year.
Monday night I am going to grease the wheel bearings and tighten down every nut and bolt on the car, plus check the gear oil in the transmission and rear end. Aside from all of that I am ready to roll.
