Specs on my engine....have industrial pistons/rods/crank..Hamilton 178-208 cam/ducky 100HP injectors/updated piston style lift pump/HX35-W? Turbo with intercooler/4" straight pipe exhaust..(no muffler)/3:50 rear gears/4 speed manual trans with us gear over&under aux trans/......
Feel that I may need my OEM 1986 industrial ve injection pump..What I need to know is where should I send my pump to to receive a full rebuild and what modifications should I have done to it to match the rest of engine mods?Or would it just be better to buy a pump with mods already done?If this route then who should buy from?Am on a tight budget but don't want issues later..
Forgot to say what truck is used for..Only for towing my e8 foot race car trailer loaded with a fuel altered drag car..golf cart..100 gals of fuel..support tool box with tools and misc stuff..so need torq to go over all the mountains and fuel mileage..

Honestly? Convert to a P-pump, give Farrel diesel service -Seth a call, tell him what's done. And what you want to do, he will have the answers you seek. And he can build you what you want

 

IMO, 3.73 or 4.10 will do you better at towing than a p-pump conversion. I've seen enough of BD's shop to get the 'warm-fuzzy' they know what they're doing with injection pumps... so thats' where I'd go.
