727 or 904

40 years ago the 727 was a much tougher piece and that's the reason they were put behind 340/360's in Dusters/Challengers/etc. Now, with the improvement in parts, a well built 904 will hold up behind most any street small block.

30-40 years ago having a 600hp engine was an unruly beast to drive on the street, that's IF you really had one! Look at what rolls around now... you can fall out of bed and build a 600hp bb that isn't rough around the edges to street drive.

Why run a 904..... ever see a front drum explode on a 904 like the "much tougher" 727? I've NEVER seen one explode. 727's seen a bunch of them go BOOOOMMMMMM! No $400+ front drum required or LBA valve body for a 904. For under $400 you can have a kick *** 904 built using the multi-spring front drum kit.

I'll take a stout built, faster accelerating, miniscual chance of detonating 904 over a 727 in a street, street/strip, hot rod A body any day of the week. It will cost less, weigh less and be faster.
