if i was to put a holley 670cfm TBI on a zz4 crate motor would the knock sensor, fan switch, and similar sensors that are on the block fit? also id need a new chip right? that way i can do away with the EGR, speed limiter, and plus the stock ECM wouldnt be able to put out the power for that kinda motor. im debating bewteen a carb or TBI so guys help me out. id also like to stick new heads, intake, cam in the 305 later down the road and put it in a s10 with n2o

 

bump ^

 

well first off you will need a new knock sensor for a 350 and the fan switch will still work but if you have not put a new one in yet you sould put one in that starts at a earlier temp, yea you will need a new chip or might as well switch a iron duke in there because it will not be too nice driving around. right now i am debating if i sould go to carb i cannt get this tbi stuff to work out as good as it sould i got too many various problems and just about every one that i have talked to have also had the thought of carb go through there head once or twice.

 

thats what i was thinking i figured it would be rough since the ECM is made for a 305 with 170hp and not a 350 with 355hp ill probably go carb im still not sure either that or im gonna get a second car this summer...either a mustang or a l98 camaro im leaning towards the camaro but maybe a stang not sure yet only time will tell
