h dog - I am really restricted on my car for height under the bonnet (sorry, hood). Had to stick with a performer rpm for that reason, even though my engine spec would benefit from a Vic Jnr.
Have toyed with the idea of machining about 3/4" off the carb mounting platform on the Vic Jr, to make it fit, but since the dual plane rpm inlet gives me great street manners (well, not me exactly, I have very poor street manners, but the engine, if you see what I mean), I think I'll stick with it for now.
The other side of an engine mounted that far up is great ground clearance - with a shallow but widened sump for
oil capacity, I have nothing lower than the actual chassis tubes. Chassis on my car is a la Kirkham - twin tube jobby.
No idea what it does for CofG tho' - track handling is not a priority for me.
