Aussie Max Wedge intake manifold and a 8-71 blower....
I have seen some 383’s B-bodies (at least 3) come from factory with a Dana 60. I “think” (no facts to back this up) it was part of a drag pak option, or something to that nature.The only cars that got the Dana 60 in any volume were the manual 440s and the Hemis. Automatic 440 Six Packs . . .
The only cars that got the Dana 60 in any volume were the manual 440s and the Hemis. Automatic 440 Six Packs, and some Hemis actually got 8 3/4" rears. Although the autmatic cars don't shock the rear end like the manual transmission cars, I would describe them as quite serious nonetheless. You may not, that is your opinion. I do, and think that most people do.
Never said using a blower and an 8 1/4" is economical. Did say using an 8 3/4" and a blower would work. Probably more expensive than a Ford 9". But I do believe just as strong as a Ford 9". I also believe that just throwing in a lowest common denominator solution is not really always the best choice. How does the aftermarket for the 8 3/4" stay healthy if everybody jumps to the Ford 9" anytime they want a stronger rear end? Or everytime somebody wants a hotter engine, they get a small block Chevy? The only reason that a small block Chevy has the aftermarket that it does is due to the >50 Million Chevy small blocks that there are out there. Using Chevy parts in a Mopar is a big no-no for me. They will work, but when the Mopar equivalent is just as good, at a non-major cost increase, pretty much puts me with the Mopar parts.
Sorry if my outburst was idiotic in your opinion. Point was, as idiotic as you may think it is, is that the Mopar aftermarket will only continue to exist if we support it. There is nothing superior about a Ford 9" over a Mopar 8 3/4". Yes, it has one additional bearing. The 8 3/4" has a thicker case. Depending on the failure mode, it may be better to have one vs. the other, but there is no clear technical superiority for the Ford 9" over the 8 3/4".
My statements are not theory. We are on an FMJ body message board. We are already out in the cold, not only with the average street machine crowd and the aftermarket, but even with the Mopar crowd in most cases. If you want to save money, if that is the over-riding concern, go with a more popular platform. If you want to stick with the cars on this board, you are going to pay more money, and parts are not going to be easy to come by. And by extension, an 8 3/4" may be more expensive than a Ford 9"; but depending on the deal at the time, maybe it won't be. Ford 9" rears are getting expensive, too. Aftermarket parts are cheaper for the Ford 9", but not night and day different (i.e. Ford 9"parts are not 10X cheaper than 8 3/4" parts).
Ed, I'm curious as to the engine build. What fuel will you be running? Stoker pistons are in the-15 to -20 cc dish. That's gonna put you at a high CR of 10 to 11:1.
I'm running a -30cc dish with 64cc heads and that nets a 8.5CR....and a 3.79 stroke.
With the 408 you're gonna need a -40cc piston.......
Good luck! Small block mopars are fully capable of making power and numbers that shatter records the ford and chevy can't shatter. Build it strong then build it stronger!Not quite sure as I haven't gotten that far yet. I do know that Scat Industries makes the stroker kit. Other than that I need to figure in how much boost I'm going to push and then decide on pistons.
Don’t forget the stress the engine takes going from full load to no-load, in an instant (if/when breakage occurs).I agree with the idea of making it strong to start with. You do not want rearends, axles and drive shaft parts flying in all directions, for your sake, and by-standers.
Second, a supercharged stroker motor will far out stress these parts than any hemi of the 60's.
But seeing as nobody mentioned anything about using a 6-71 blower, I again, fail to see your point.
