If you have the Money then putting it to the test is the best thing to do all I was saying that with the 434 in my car the 1050 did slow it down. and that was what everyone told me it would do but I'm a hard headed Guy. but like I said if you have the money try Both that way you know for sure. If you were taking bets on it I would put my money on the smaller Carb though . either way Best of Luck to you. and post the results we would like to see for future inquiries.
and be Safe.
