Lsx DR crate eng .....Huge port. Head was sold with 313cc DR head = Huge.Hey All ... does anyone have personal or dyno experience with one of these ? ... It's my understanding that these came on some crate 454 LSX engines .
LS7 ports are smaller all the way around , looks like I will be gasket matching the heads to the intake ... height is right at 8" ... the plenum top has been opened up quite a bit , I will likely have it milled down to where a 4500 throttle body with gasket will seal it , I think I can take 1/2" or more off ... it also looks like the manifold attaching bolt bosses were spot faced with a masonry chisel and sledge hammer ... this was off (so I was told) a tall deck LSX block and milled to fit the LS7 heads ... I will definitely need to have that work checked out too !!!How is the port alignment and do you know the height from the valley plate to the carb flange ?
It supposedly came off a 454 crate motor ... probably what you are referring to ... I haven't found any info on it beyond some of the obvious and what little I learned from the PO ...Is that from the discontinued 454 lsx-R?
i was going to ask if the top and bolt bosses were 'adjusted' with a chain saw. hopefully its recoverable.it also looks like the manifold attaching bolt bosses were spot faced with a masonry chisel and sledge hammer ...
I got about 1200 reasons...A dollar for every reasonLet me raise my hand and ask. Why this intake instead of a CID? To me the port alignment on the corners would be way better w) the CiD. This does seem lower profile, though, if you have a hood clearance max.
