Ideas since rebuilding
 

Ive seen alot of stickys out there and was wanting some input on what should be done to prolong my truck since im restoring it from ground up. Its a mix of about 3 different years 90-92 reg cab long box w250 5spd.
Ive already put arp head studs in, KDP delete, new gaskets throughout the whole motor and seals, new lift pump 2nd gen style not sure if it low pressure or not but pretty sure it is, south bend clutch pressure plate and flywheel kit (425 hp set) and changed every bushing in the chassis, cab and both motor and tranny mounts as well.
The motor and tranny are not in the chassis at this time as of right now its a bare cab and box on my restored frame and when i say bare cab i mean nothing inside of it only doors and glass.

So im open for suggestions as to what to do to help it last long and also gain some extra ponies.
