scmb 05-28-2002, 12:24 AM Hey, I am planning a v6 swap this winter and thought I'd ask anyone w/ a vortec v6 and something close to 4.88 gears what size tires they are running that the engine can handle turning on the street. People w/ yotas were saying that they are turning 38's to 42's. 1TFROT 05-28-2002, 10:03 PM I can't see a problem with that. my '00 4.3 is turning 33s with the factory 3.73 for now and it does just fine. I'm running about 2 grand at 75 mph in OD. I added the K&N and Hpp3 and it was a nice gain. before I added the lockright in the rear I could actually break the rear 33s loose for about a foot. (had a gov-loc) I will probably goto 4.56s when I jump to 35s (same time as SAS) just make sure the vortec motor you're using is strong to begin with rochog 05-30-2002, 07:16 PM hay steve good to see you around I have a 95 4.3 with 35 boggers and spooled 456 it runs great. Sometimes it hunts for od and 3rd going up hill but other than that it runs grreat 1TFROT 05-30-2002, 08:39 PM hey, good to see you too. how's the blaze doin? :smokin: rochog 05-31-2002, 04:46 PM sweet I seperated the front d-shaft on tank trap about 3 weeks ago. I put it on an RTI ramp and it ramps about 1125. It rides good to for leafs on the front. gas sucks thought 13.6 miles to the gallon. GonZu 05-31-2002, 07:08 PM Newbie here- My advice... Go with the 4.56 gears ! I'm running 33" (32.5") tires. Sometime in Sept.,,, my new 5.38s will show up at the door via UPS :p You should have NO problem with 33s or 35s... other than that, you'd better check the drive shaft & U-joints :skull: Do you have any lockers ? GonZu hmmm... 42s sound reasonable too :beer: | |
