It’s now a 553iS BMW with a shiny new Chevy 5.3 V8

Well, not completely, but Old Red now has a new engine sitting in the engine bay. And we’ve learned a whole bunch.

Ed Raether’s motor mount brackets work great. A passenger side Camaro exhaust manifold works good. Plenty of room at the firewall and at the radiator.

Issues: Tight quarters on the driver side. Just for fun, we put the SUV passenger exhaust manifold on the driver side making it a front dump. One idea is to make a cross-over pipe and send both pipes down the passenger side. The manifold clears the steering box and master cylinder. PS box will need a 90 degree fitting for the return hose. Manifold flange will need some grinding. Maybe a Camaro manifold would work better here too.

Here’s a question for you: The SUV intake and alternator are too tall for hood clearance. Which would you do?

1. Swap the intake for a passenger intake which means also swapping the waterpump and all the front accessories?

OR

2. Install a cowl induction hood scoop, say something like the early Z28 Camaros had?
