4:10 or 3:73 is what you need if you have an automatic are towing. If you have a stick, 4:10 or maybe even 4:56 if you have the biggest tires. The LS is more of an RPM motor than the regular Small Block, so you need shorter gears.So... After pulling my 5000 lbs boat up to my favorite lake for the first time with Bubba, my newly LS swapped 1978 K20, I've decided those 3.42's have got to GO!
Having no plans to lift the truck or go to anything more than *maybe* 33's (Currently 32's) I'm going to put 4.10's in it, like the donor had.
Running a 14 bolt rear, GM corporate front. Looking for all inclusive kits that'll get me back on the road in a weekend.
Does anyone have a link to good kits for the regear?
Any advice? First time on this job...
