Frankly I like a bigger carb, but then I ran a 1250 on a 447 SB2, plan to run it on my 461. If your 1050 runs well you won't find a lot of difference, I saw about 20 HP on the dyno between the 1050 and 1250. I wouldn't waste my money on an 1150. You won't see enough difference to be worth it. Unless you plan to put a pair of them on.... :shock:
