Interesting Dyno Tidbits

[55 Fargo]

Hey all,

watched a very recently uploaded You Tube vid, on a complete rebuild and dyno, of a 225 Chrysler Slant 6.

it was professionally done, so not some backyard home video, made on someones I phone.

So engine was rebuilt, .040 pistons, .010 crank, hotter cam, but nothing too wild, Offenhausre 4 bbl intake, Edlebrock 500 CFM 4 BBl carb, and Hooker Headers.

This engine was installed into a 1971 Duster with an A904 trans.

this engine, dynoed at 135-140 hp to the rear wheels, not bad, for a stock build and auto trans.

Old well worn 225 engine dynoed at 70 hp, pretty dead...

I recall Greg G, stating he was able to get 127 hp to the rear wheels, with a basically a stock rebuild.

Anyone else have any dyno numbers on their Slant 6s or Chrysler flathead 6s.

Pre 1971, and very optimistic I would say.

Yep, no alternator, vehicle exhaust system, or cooling fan.  And likely adjusted for marketing purposes.

My 80 Volare has 100 hp net. Maybe now after I have redone a few things
