383 or 440 Dilema

Had A 440 sitting here to put into an Aussie A body Valiant, Then a 383 came my way and It made me think , What would be the best for the old girl . got all new suspension already there plus 8.75 diff. The first thing is weight vs stroke another is of course space for headers plug wires etc , Just got A manual reverse valve body for a 727 which I orginally purchased for a SB 360, But put a Lokar cable kickdown on Instead,

Which way would you go and why, Oh yeah Its street and strip probably 50/50 :burnout::burnout:

I have the same dilemma. I'm going with a 383. Plenty fast for the street, have an almost stock 383 Formula S that I used as a daily driver for years. It comes down to useable RPM for me. All things being equal, the 383 will make power at a higher RPM. These guys are making 600 HP through 3,000 rpm with a 440, but it is over at 5,600. I figure with that kind of power, I now need a Dana 60 to hold the rear together. I really like my 8 3/4 rears. It is your car, your decision. I just thought I'd give you my thought process and conclusion. As usual, missed it by that much...
