EC tillotson has the carb and manifold you need .
If you intend on using alcohol you be prepared to change the oil every day you run the engine you should use oil that is alcohol compatible like fhs 62r or any of the other good ones.
I suggest getting a billet rod because once you install the hl380 or hr 181 Tillotson carb the engine rev way pass 3600 rpms and you will break the stock rod get yourself a billet flywheel also for safety.
I build these engines all the time pm me if you have any more questions.
