To what extent does a single four become impractical? Is there a point on a small block when a Twin carb T-ram would be the better route? [/quote]

I sold my 405ci W-9.. but on it I was gonna make a cam
change and go with a pair of 1050s on a T-ram..I dont
know when it becomes impractical but the T-ram was gonna
be my next step.. and the cam was gonna be .160 more lift
I already had the pair of 1050s.... this pic is my old 340
