I'm returning my boat to stock. It had a carter/weber carb on a 330hp 454 (1993). I sold that carb long ago and ended up with a Q-jet for a reasonable price (trying to do this as inexpensively as possible). I guess it came off of a 370hp 454 mag. I wondering if anyone can help me with jetting. What jetting would be appropriate? I can't find any exact jet size numbers either in the manual or in Moores book

thanks

i would just run the carb the way it is,,check the plugs anfter the first run and go from their..if i remember the 33o hp carb had bigger jets in it

your fine there is one size jet more on that carb. i took the one off my baja and put it on my formula that has a 330hp and it work good
