The Stovebolt Site Forums The Parking Lot Big Bolts Gas burner truck speed/RPM in days past

Love that site. Max HP/TQ as per GM were 3,600RPM/2,400RPM net, gross 4,000RPM/1,600RPM.

What I'm more interested in is how they (292's) take sustained high speeds in the real world. Everyone (today anyway) seems to be afraid of the longer stroke vs., say, a 250.

But, the way I see it, the rod/stroke ratio is actually slightly better, and you get 3/8" rod bolts. Pistons are 24.90oz, 327 was 23.46oz. Seven main bearings to keep everything stable, and later engines like mine had 12 counterweight cranks.

I just don't see what makes it so intrinsically hard on itself at high speeds. Obviously it's going to suck fuel at 3,500RPM and not really make any more power, but I don't see why a 250/350/454, etc. can do it and a 292 will self destruct like some seem to think. It was designed for heavy trucks with deep gears, after all.
