Soooo, 500 cube small block Mopar is possible, and yet, I have never heard of anyone building one!

My only question after seeing this post is why has nobody ever built one before now? Why is this all of a sudden common knowledge, yet I have never heard or seen anything even close to that in a sbm before now.



Ron's old motor was 474 inches..... INDY sells a 471" Kit now off shelf....

All it takes is a big crankshaft. Most guys doing SB Mopars are not willing to spend the $ to be honest.

However, a 4.5" crank in a SB package will not really be a great "race motor" combo (it's too much stroke IMO) That's really why no one has done one.... It's unusual to spend this kind of $ on a motor that will not be a max effort deal.

The 4.25" crank would be as big as I'd go for a race motor that needs to turn RPM & make big power.

The journal overlap on this 4.5" will be scary with 2.0" rods.
