Pontiac intake?
1976 firebird 400 stocker build. NHRA bluprint guide says intake manifold casting number needs to be 496140. Every other source i find says that is 1975 only and 1976 and 1977 are 525355. Also, i found a stock 1976 firebird in a salvage yard today and it had the correct 6x-8 heads and the 525355 intake. What do i do? Thanks for the help
