I think you would be happier (more power, less heat) with a 3300, based on an engine I put together for Stokerwhore a number of years back.

the 2.3 may good for like 3 psi boost but if you want to make boost beyond that for a 502 cu in deal your going to have to spin the little 2.3 blower way too fast. while that set may have been "ok" back in the day, if you want to make real power sell the motor you got an build a blower motor. half assed builds will give you half assed result- for a little while. the 502 did have good parts in it if i remmber right

A larger blower can move more air per revolution. In order to get the same amount of air with the smaller 2300 blower, you have to turn it quite a bit faster, which generates more heat. Once you do that, you are not adding power even if you see the number on the boost gauge increase, since it's hotter, less dense air.

I mentioned Stokerwhore's engine because he does have direct experience with the same engine and first a 2300 (which made heat and burned a piston), and the current 3300 Whipple that is on it, that has been flawless for 7 or so years now.

I do understand the space constraint. Depending on what you would spend on the blower you might have yours rebuilt with a stroker crank, 540 cubic inches, and get somewhere above 600 hp with a mild pump gas engine.
