Anyone using the 3.91 stroke 400 block?

After calculating some things I tend to like this setup on paper with head flow numbers and HP to rpm ratios. 467 CID should be plenty with some stealth heads and a tunnel ram with a .620 solid cam. Anyone have one on the road or strip that would care to comment?

I ran 4.10s with a 451 lowdeck in my duster, had a 28" tire, ran 10.9s all day long, very streetable.

I dont build anything bigger in a B wedge than the 3.915 crank. It's a very well balanced and long lived combo.

Yep.I have one in my 69 B'cuda,4spd,3:73 street toy.
Eagle crank,Manley H-beams,Diamond pistons(10.2:1)OOTB Eddy 84cc heads,Comp street solid roller(242/[email protected]/.576 lift) Eddy RPM intake,Holley 800 DP,CPPA underchassis headers,3" ex w/x-pipe and 3" tailpipes.
Runs great! Idles at 900 rpm w/12" vac,great low end grunt and rpm's like a chainsaw!!:-D 1st and 2nd gear go up in smoke pretty easy!!

I just helped a buddy put one together using 440-1 cast iron heads and about 13:1 compression. Used about 100 lbs of ballast in the car and ran 6.50's in the eighth mile with the car weighing 3500 + with driver. The car was a '69 Dart. The combo used 6.70" long chevy rods and 1.31 cd pistons.
