> Not to mention that the LT1 is reverse coolant flow. You need a LT1 specific manifold due to Vortec style ports, different bolt patern, and the fact that there is no coolant cross over or disty hole in a LT1 intake. GMPP makes the only carb LT1 intake I know of.

the intake i habve works just fine…it has the hole for the disty and the coolant crossover in the front…
