No reason that is, unless you've already got pretty healthy compression with larger chamber heads. The 54cc units could make pump gas a no-no in that case.trkklr77 said:ummm small block heads are small block heads. some just have a realy small chamber [54cc] there are 2 potential difference, accy mount holes in the face and steam holes for the 400sbc. neither are any reason not to use them.
Why would it take machining? Both utilize a 3.48" stroke crank.s10bogger said:You could get the crank, rods to fit (with machining)
The crank in a 305 and 350 have the same stroke but the crank will never balance because of the weight difference of the pistions in the 350 and 305TEX said:Why would it take machining? Both utilize a 3.48" stroke crank.
