Does a '90 258 4.2L exhaust/intake manifold bolt up to a '78 258 4.2L. I have my MC2100 on the '90 and picked up a '78 that has a 1 bbl Carter on it. I cannot look at the two side by side until Sat. and was hearing it may be a problem. If so can someone suggest a solution to the problem...if there is one.
