4 years ago? Are you smoking crack. My electric fan has only been on the truck for 7 months....Electric fans will work great, my bro in law runs one on his 72 k5 with a cammed big block and we hit trails in desert heat and he doesn't overheat.
Oops went tarded didn't tealize this this was like 4 years ago.
Since this was bumped, I'll update it. I found out the hard way that you can't put 12 volts to a cs130 alternator or you'll burn it up. So I have a new regulator ready to go in.
The carb issue, I tapped on the carb with a dead blow and got it to quit dumping fuel, but the rear throttle blades are seized up so I'm just gonna take it apart to clean it out.
This weekend I pulled the truvk in the shop and pulled the axles apart to regear them. Wish me luck, I've never regeared anything nor have I seem someone regear anythjng.
