carb for slant 6

Yes I know but I pretty much stole the thing and I'm just kinda wondering what people have done to run that size of carb
It all really depends upon
1) your total budget, for the engine, transmission, rear end, auxiliary systems like brakes, cooling to name a few.
2) your plans - goals for the car, is a daily driver, a full time race car, drags or auto cross?
Figure out what you want to do with the car then see if that carb fits in. If it does not, move it on to someone that can use it.
