These are cool but what's wrong with the 6 cylinder version? :rolleyes:

Dean Polopolus originally built these engines as a high performance, "bolt-in" engine for the 356 chassis.
IIRC the first engine was installed in Gary Emory's wide bodied 356 vintage racer "El Diablo" that was quite often piloted by Milt Minter.

So they're a "relatively affordable" alternative to the Carrera 4 cam engine.

Well, not as cool as most of the engines posted, but...

Miata engine

this is also a miata, but not exactly a miata engine... (sort of like a modern day cobra)

Certainly not your standard Miata engine. Very cool!

Relatively affordable? They cost $25k+ so compared to the $32K I charged for the last 4 cam engine I overhauled, I guess more cost effective would be an accurate statement.
