I was told by guy today on the phone that a built 383 will outrun a 400 any day of the week. Now, this guy was calling about 71 newport that Im selling, I listed it for $1000 and stated that I would be keeping my 400 engine (cause its a 230 cold weather block.) He wants the whole car, and Im guessing he is telling me how much better a 383 can be built than a 400 because he wants my 400. My first thought to his statement was, uh you can make a 340 outrun a 400 if you have enough money.. its all in what you do to it.
So, is there some key feature to a 383 that makes them better blocks for high horsepower and stroker combinations? and not for unlimited budget builds, lets say the the budget is $8,000 and you wanted a reliable 650hp street/strip car

Bump the price up $1000 then I will drop off a complete one at your house next month for $750 when I go to Seattle.
You make more money and do less work He gets his silly numbers matching 400 2bbl And I sell a spare engine sitting around.

Don't agree at all. All a 400 needs is compression. It has a cylinder bore even larger than the 440. Loves to rev just like the 383. My slightly modified one in my '65 Chrysler moves it very well.

Of all the "conventional wisdom" about engines , the Big Bore - Short stroke deal is the truth. It Works! The bigger bore is always, always better. Two of the baddest big block Mopars I have ever seen were 4.500 bore and very short stroke. They made massive power. I likey 400's any day!

Slightly OT but a 400 with a 440 crank is a good plan. I see 440 steel cranks on occaision for $100-125 & this combo (451) or offset grinding the 440 crank (470) yields plenty of cubes & the B block is a better fit in an A body & look what Andy got out of his 470-550 horsepower! Yes he had killer (alum) heads which you're way ahead to go with them anyhow rather than antiquated iron heads but it is simple & easily doable. The biggest expense (besides the heads) is the pistons but you're gonna need them whichever way you go.
