Ls1 & ls3
We have come a little bit stuck in trying to find exact measurements for the LS1 intake, I understand the ports are a different shape between the 2, but need the other dimensions, width or manifold, Angles of heads,injectors, and Manifold bolt locations/centres, and dimensions etc. if anyone can help me that would be fantastic, normally when we develop a manifold the customer will bring in the engine and heads, or we have been able to find the info online, but the LS1 information is proving elusive.
