Help Needed w/ 4-carb Chrysler 150 Stacker

[RogerH]

I will be building a 150hp Stacker and want to use this 4-carb intake on the motor. I have no idea what reed blocks and carbs should be used. I was told that the 50hp might fit. Note the bolt pattern for the reed blocks. The motor has high compression heads and some healthy porting.

Any help identifying the reeds and carbs I need to use would be appreciated. If you have some for sale, that would be even better.

Thanks,
Roger
