I have used both steel and alu none made a differance on the dyno, they all will punch the pushrod end out once in a while

I use the bop seal in my engines and they are great!!

I think TA Performance, and Silver Seal both, have new replacement timing covers with oil pump assemblies. I blueprinted the oil pump and the passages, using the high volume pump/timing cover. I used to make an externally adjustable stop for the relief spring, so that I didn't have to try to play with springs.

Mike, in my opinion, you can't spend too much time on a Buick oiling system.
When you analyze it, you'll see that that rear main bearing's oil is, effectively about 3 ft away from the pick up..
Drill out the pick up passage in the block. "Port match" all the transitions in the oil passages. Use the T/A parts to blueprint the oil pump clearances, use the adjustable PR stop . Baffle the pan in the rear etc,etc,etc...
When you get all done, don't be alarmed if you only have 10-15 psi at idle after a run!
Rev it up a little and watch the gauge. If you have at least 10 psi per 1000 RPM's, you'll be fine.

Every one has been so much help, i have ordered the parts to convert the rope seal, and a adjustable oil psi kit from TA. I have done a lot of reading, but i know that i can read all i want nothing is better than getting help from people that run a buick. How many RPMs is to much on a 455, and is their a legal way to beef up the webbing on a 455 block? i heard that main gerdals are NOT leagal? i ordered a cam from bullet, the carb was done by mike walters, but that was years ago! My father ran my GS in G/SA befor but was short lived as we spun some bearings because of bad cam bearing instalation. thanks for every thing guys cant wait to hit the loud peddal on it.

Mike, I spin my motor in the 6100+ range with a 4.30 gear. I know when I changed from the 4.10 (5600-5800) to a 4.30 the first thing that failed were rocker arm shafts. I run the TA thick wall rocker arm shaft now. If I were you I'd start with a 4.10 gear, my motor never broke one stock RA shaft in the 5600-5800rpm. Mike I've never had a main bearing fail, I think as long as you get good machine work done i.e. line hone, crank grind and clevite bearings your motor will live a long happy life. Good Luck, JKeihn 3954 maybe I'll see you at the Norwalk LODRS
