Chevy 350 YJ
« on: 06/28/16 - 11:04PM »
Been a while since I have been on here because I didn't really have a reason to.  However, a few days ago I picked up a 1994 YJ with a Chevy 350/TH350 and a NP 241C drive-train.  It is sitting on 35in mostly bald tires.  Worked on the trans for 2 days but no luck, took it to a shop and found out the trans had water in it.  Its in the process of being rebuilt and should have it back thurs/fri.  As for now the drive train is out and being cleaned up and new parts are being ordered.

Not a lot happening over the last month or because I was out of the country.  Got the transmission back and the drivetrain installed.  The adapter between the transmission and xcase is leaking transmission fluid so I have to pull it back out and get a bigger oring I suppose.  I changed the valve cover gaskets because one was leaking.  It still doesn't have exhaust but I figured I would drive it around town since it had been sitting for so long.  I am taking to get the exhaust done on the upcoming Monday, pricing windshield replacement, and tires.  It has 35s with 4.10s and the RPM are through the roof.  I was thinking about removing the 1inch body lift and going with 33s to hopefully make it more street-able.  Yes, no, maybe? I am open to opinions.

Correct me if I am wrong, but wouldn't going down in tire size make the RPM's go even higher? 

When I went from 30's to 33's before I regeared, my RPM's went down quite a bit and I consistently had to downshift to keep RPM in the powerband.

Sounds like you might need to step up to some big-boy tires...38's anyone?

You are correct, same here when i went to 35's with 4.11's I lost low end and can only use OD on very level roads lol. I need to regear---4.88's or 5.13's but hard to justify since I don't hardly do any highway driving and my transfer case is already low geared.
