Ok, how should i break in the 355? Should i wait until all the prominator stuff gets here or can i drive it until it comes? I don't want to wash down a ring or spin a bearing from too much gas in the oil but i don't know if that would even be a problem... my first couple oil changes(when i had milk in it) smelled like gas but it wasn't running right because of vacuum lines and a leaky manifold. I got it running right after that and now it idles and runs like it should but I still haven't put any miles on it just up and down the street. My question is (once i get power) can i drive it without the computer tuning stuff? Motor has holley 670 cfm 85 pph injectors holley projection efi dual plane 2" intake manifold crane cams hyd. lifter replacement l-79 cam .447 lift .222 dur Camel hump heads speedpro 10:1 flat tops accel inline high pressure fuel pump after burner headers and y pipe 3 inch single ex. k and n I bought the accel pump so i could support more power. the motor should put down 340-350 hp with the prominator but I won't have the prominator for another month or so. Will i drown my rings or can i drive it around town until i get the prominator and tuning stuff?
