The performer intake is a pretty good intake. I have the #3776 which just has the EGR on my 360 truck engine. The port at the gasket surface is sized for a 318 head, but when I went to gasket match my intake, the 318 size was actually reduced from the true port size of the intake (true runner size is about same as the 360 port. I think maybe 1/2" deep gasket match opened the intake up to the 360/340 port size.
$70 is a good deal if it's in decent shape.
