Folks, I fell off the couch.

SPIKE TV has a show called Engine Power in their Powernation series with Courtney Hansen. They are putting a roided out slant6 in a 71 Duster. Friggin Chevy guys must be puking right now.
 
Let them puke. They know there are some built slants out there that kick ass regardless. :laughing7:
 
I'm a little disappointed with the dyno. I'd like to see that slant hit like high 200 hp and 250 ft lb of torque. Maybe a wet system spray?
 
I would think a 360 with aluminum heads and aluminum intake would weigh in the same neighborhood as a slant. I wonder what rpm comparisons could be made. Could a built slant run 10,000 rpm? I don't believe the small block revs above 7500 with out some serious built components.
 
FABOians say that after 6200rpm, small blocks need oiling modifications.

I would rev a 170 crank in a slant block as the 225 is like four inches of stroke.

http://www.forabodiesonly.com/mopar/showthread.php?t=302106 they are arguing about the merits of the venerable slant 6.

It needs a closed chambered aluminum cylinderhead, typical upgrades, and a turbo charger.
 
Straight sixes generally don't rev as high as V8s (could change for specific engines being compared). The crank on a 6 cylinder is longer than the crank on a V8 (and much longer than a V6), and tends to start flexing/whipping around at lower rpm at lower RPM than a V8 or V6. This flexing/whipping tends to do bad things to the main bearings. I don't know what the actual rpm limits are, but the typical longer strokes on a straight 6 don't make the situation any better.
