Spent yesterday scraping the cam bearings. Now the camshaft turns by hand. (My first time so I had that cam in and out about 10 times) Don't know what happened between the machine shop and my assembly but the cam barely went in. I called the shop and he asked me to torque the main caps and try it then. Did so and it turned a little easier but I still had a few high spots to scrape. Then had to wash the block again. Tomorrow:The Crank (I've already checked the clearances on all the bearings. All of them at .002)

There's something very un-natural about scraping at a new bearing .

Yeah, kinda scary but the mechanic said those bearings are almost solid babbit. A fourth-hand comment on Moparts said the factory wasn't very particular about boring the block and made up for it by installing thick cam bearings and then line-boring the bearings. Anyway, it's kind of nice to think you're actually building a motor rather than assembling some pieces. My next "make it fit" delay should be setting the ring gaps a little wider (recommended for supercharged engines)

got her out of the shop, had extensive work done. rebuilt rr leaf springs, new KYB shocks, rebuilt trans, stall converter,new master cylinder, plugs, wires, distrib cap, starter motor. I put a lot of money into her, but a 36 year old needs to be young again, she sits higher, handles, and rides better and her performance has greatly improved. struttin' her stuff

I just threw new tires on mine, BF Goodrich Radials. 275/60/15 on the back and 255/60/15's on the front. Sure rides alot better than those old crappy truck tires I had on it! Now I just need to rebuild the suspension so it doesn't bounce so much

Picked up the RT tail bezels from the powdercoaters today...they've been powdercoated satin black. They look mighty nice. Also wired up the LED arrays to the second tail light. They should both be working and reassembled by tomorrow night. Yay!

Crankshaft and camshaft are in, both turn by hand. I need to decide how much advance I want before I install the timing chain.
