Ok guys I searched the forums but haven't found a solid solution. I'm about to buy a 99 24v and when you turn the key on the wts light won't come on at least not right a way. If you bump the starter and stop it'll come on then crank right up. If you don't wait on the light it will just spin...

Alright, got the swap done, and up and running a couple months ago. Immediately into the test runs the tappet cover gasket blew off in three places. Along with other bugs I began tearing it back down. Now over two .months later it is back together. First run down the street....... Tappet cover...

Finally got the build running and partially driveable but I'm in a pickle on getting a fan or fans. Due to lack of room under the hood with the cummins in the Chevy I'm looking into fans. From what I read the factory mechanical fan will move 8500 cfm. I'm really interested in dual 15s but only...

Alright I've done some talking and research and can't find a good set of hydraulics to rig up in my convert. It's a square body Chevy 4wd 90 model. Last of the one tons. I've got the dodge slave and a Ford master. Master chosen due to good mounting. Problem is it will not mount to the factory...

Hey guys just looking to follow up on an order. I was told I should have received pieces of it but haven't gotten any feedback to why I haven't. I'm sure yall are super busy just need to see where I stand. Not sure on the order number but the name is Josh Supak. Thanks guys.

I'm slowly getting started on my crew cab 12v conversion and was wondering... All yall guys that are boxing your frames, how far back is necessary? I'm thinking from the front to right under the cab. Any suggestions???

Well I'm slowly gathering up all the stuff to convert my old Chevy crewcab to 12v and I've got a friend getting rid of a stock intercooler out of an 07 classic dmax. I haven't gotten the dimensions yet but considering if it'll fit would it be a able to do what it should in my project or would it...

Planning on putting a cummins in my 90 model 3+3 and I've got tons of info off the forums so far.but one thing I haven't run across yet is..what is everyone doing with Tue ecm's from these trucks? Do I just unplug everything and not worry about it or completely pull it out?

Hey guys looking for a bad nv4500 to buy pretty cheap and use for a core. I'm tryin to start a build and defiantly try to go as cheap as possible rather than paying full price. If anyone knows of any laying around for that would be awesome. Anything around a 95 model 4x4.Thanks!

Well so it begins! Going from tbi 454 and a granny 4 speed too..95 12v with new nv4500 and np 205. Now luckily this is the last of the square body chevys so from what I've read it will be a good match. My biggest question is what is the best way to run my fuel from the tank to the pump and is an...
