if i remember they are essentially plug and play just a ground and i think i used a 30 or 25 amp fuse so its pretty easy they seat heaters for the win im gonna run stock gm inserts instead of forking up the 200 buck for a pair of them
are you talking a 305 tbi to a 350 tbi because its not as big of a power jump as most think it is i have a 350 in mine and compared to my buddys 305 its not that big of a difference and i have a 1570 stall tci converter id be willing to part with by the summer
either way sounds like a fun build to do there is a guy on ig that has a diesel lib on 33s and belly pan etc looks to to a fun rig to wheel small track width and a decent amount of torque so i look forward to seeing it happen
i saw a guy last year at KOH that had one with yota axles sat low but never seen just like just super mild except my friend has one with a 3 inch rancho and lockers so
it can be done but personally dont know much either
