[QUOTE="Johny25, post: 273813, member: 7791"] Oh now I remember why I advised people to buy one instead of reaming or porting there old one. I didn't take a pic of this when I had them off together but the larger intake is taller......meaning if you lay them both down flat with the carb hole facing up, side by side the 0396790 is fuzz more than an 1/8" taller (if memory serves me on the measurement lol) than the 0396788. So there is no way to ever ream the smaller one to match the air flow of the larger intake. It is just not possible with the smaller casting of the 0396788 mold. [/QUOTE]
