Just had to get the intake redrilled for the LA bolt pattern. My intake was cast for magnum heads. I was running this intake on my 360 magnum with EQ heads before I switched to the trickflow heads.
Are the port openings in the magnum version of the Indy intake pretty close to a normal Magnum size?
I haven’t had a regular Indy SB rectangle port manifold(360-3R) here in ages, but I recall those as having the W2 bolt spacing, along with ports that are wider than std LA heads.
