on my 86' it came stock with Hydroboost, and im puttin an engine that was ran with vac. but i kno that dosent matter b/c you can put a cap over the vac. port, heres my deal i dont want to go through all the trouble makein b/s powersterein lines plus if you pump desides to take a shit on you it can hurt a lil, gas engines always pull vac. plus vac. boosters are the way to go in my eyes but i dont kno if it'll bolt up to my firewall correctly, any got any answers??? what would you rather have vac. or hydro??!!
