hey IM looking at 89 RW713 V8, 450(24,000k), 14300 & 44's on rears, 20000 lift axle. pto, 135 gal. tanks. dual exh and air cleaners. I will have to strech it approx. 30" to 32" when I get it home I will post pics and tell you guys the price! but I have a few questions. Its got 22.5 tires, 8LL trans and rears are cdr92's(4.45) what will top speed be? do I leave the 8LL in it? do I change crown and pinion to differnt ratio? I have a good 13spd, or spend the money and buy a 18? It looks to have an oil leak on the right side of the acc. drive. is this common? easy fix? can it be some thing else? the exh. manifold has a tiny leak on the pipe going to turbo. the rad was a bit low, I notice the heater hose was leaking at the heater core after start up, it was idelling for 15min, oil pressure was 60psi, and slowly droped to 28/30psi, water temp was 150/160, when I noticed the over heat lamp slowly comming on. could this just be cause the fluid was low? or bad switch? I belive it has two temp censors? the steer axle is a 14 3#, I will need to change it to a 20#, it has 2 steering boxs already, will i need to change the axle? or just hangers and leafs? to me the motor didnt seem too strong, with only having 24K since rbt at the dealer, by a good engine man. the truck has been sitting for two years only being started and moved now and again, it did smoke a litte white on decel after jake turned off. Is that from sitting with stale fuel in it? does it need a good work out to come alive? I havent drove a mechanical truck in quite some time, and am used to my hopped up 460 18 spd. should this 450 outpull the 460? I know some of these questions have been asked before but too bad! Im asking again! LOL any help and info will be greatly appricated! Its not the truck I need, ITS THE TRUCK I WANT! BOBO
