Default Best mods for pulling

Ok guys getting ready to buy a 1993 doge 350 dually extended cab long bed dually with the 5spd. Gonna use the truck to hook in the local work stock class, and street drive some. The truck is in great shape it's bone stock so I was wondering what would be the best mods to do to this truck for sled pulling???? Besides a p-pump conversion, that most likely will come in a year or so,most likely it will become a dedicated puller.. Never been around the 1st gens too much always had the vp44 trucks so any help is appreciated thanks guys

They don't make a DD for those if I'm not mistaken. And if you're pulling in work stock, depending on rules it has to be a stock turbo

Southbend and valair both make DD's that will work but be warned, its not if your input will break, its when ill it. I had mine cryoed and it has held, so far....

And with 5x14's the stock turbo will get damn warm, but then again I put a he351cw on mine and I can still bury the gauge, just not near as fast.

In Indiana it just has to be a stock appearing turbo, according to the rules that I've read, I could be wrong, I know my cousin pulled work stock with an s300

go ahead and swap in a nv4500 if you can. also alot can be done with the stock charger to make it pull right with the S300's and still be WS legal
