Friend ordered truck new. 3/4 4×4 nv4500 454 373 gears with g80 cruise tilt no air. He plowed snow with it its whole life. Frame is ugly under the cab and has been plated with 3 inch 1/4 wall angle iron. I got it with a slipping clutch for$1100. Was going to put a clutch in it and drive it but changed my mind and decided to use drive line in a different truck. Wife wants junk out of yard so I went out and looked at it. He sprayed the body down with used drain oil regularly. The body is crusty but not bad for pins are like new and it drives tight only has 60k miles. I've decided to make it my winter ride no snow plowing. Save the good trucks for good weather. I've got a different trans crossmember to replace the one that broke when I went to move it. I put about 70k miles a year on running to work on freeway. My plan is 255/85/16 tires, long tube headers, egr delete, cat delete and 0411 swap. The manifolds are junk and leaking and and truck is lazy. I'm not pulling anything more than a little utility trailer. What do you guys recommend for clutch and long tube headers?
