Hey every one! I am currently working on a build and not sure which route I want to take. The truck is an 83 with the 22r currently. I want a fun race truck, the 22r needs to come out. my previous builds include mustangs, rx7, supras,BMW, AUDI, etc. New to the truck world. I need a new power plant I have already started reinforcing the frame for added power(thinking 600 or so) what engine would you recommend? Keep in mind I had a few ideas myself but wanted to get everyone else's thoughts and opinions. Also keep in mind i live at an altitude of over 8k feet so carb is out as well. The second part to this is suspension. I want to either go complete coil over and lower it a bit or airbags. I have 0 experience with airbag personally if i went the airbag route it would be strictly for comfort of ride and adjust ability on the fly. I have yet to find a coil over conversion kit or much info on what would work for this truck. Maybe someone here does? I know there will be lots of fabrication here and i have the money to spend. I can do almost all of the work myself , and have a welder on hand when needed. unfortunately the information on the truck world for lower race is not there. If I wanted to lift it there are a million resources but nothing for what im looking for. Thank you all in advance.
