The LD340 doesn't look that close to stock to me, with the front runners reversed and taller.

Closest thing to stock is the Mopar M1 dual plane below that is I think out of production.

The Stealth is a good intake. Felt better even on my car even before I port matched it, than the RPM Air Gap. For the coil I just mounted mine on the firewall.

One bad part about the stealth is that the port sizes vary greatly on the same manifold. In general they are 318 sized instead of 340/360. Though when I got around to port matching mine I would say 4 needed a lot of grinding, 2 some grinding, and 2 were already almost the larger port size.
