no, all you have to do is take the top end off and put it on the 350 then slap it back down in there and bolt it up. are you using your heads off of the 305?

No I have a 350 long block. People told me I might have to do a 350 throttle body cause the 305 run lean compared to the 350 running rich what do you think

as far as i know a throttle body is a throttle body it dosn't matter what motor it's off of. ask them people if they have piston return springs

what year is the 350 block and heads? the reason i ask b/c the pre 87 heads won't line up with the holes in the intake correctly b/c of the angle of the holes in the head unless you have the intake milled. i think it's easier just to get a set of 87 and younger set of heads

I've heard the 350 uses bigger injectors on the same throttle body, a different chip in the computer, and a different knock sensor.
