I have a 1993 chevy full size truck that i am building a motor for. I am useing a 91 350 block that has been bored 30 over with flat top pistions. I am uesing the heads that was on the motor and had a vavle job done and new springs that will hold up to a 500 lift in a cam. I am still going to run the stock t body fuel system on it for now till i can get a new holly t body for it. What i want to know is how big of a cam can i run while still useing the t body and computer without it messing it up or making it not run right? I have heard you can use any size but i would like to get some info befor i buy. I want the proformance but i want the sound to that usley comes with a cam. So let me know what yall think.

Thanks.
Brandon.

i've run a 268 cam in a 94 motor, heard 277 works, tho that's gettin a bit lumpy. the 268 worked real well.
