Good find!
I rest my case, about the "accuracy of the so-called industry bibles" including the Essential Guide, because the Guide obviously missed this one by a country mile!
I know for a fact that there are numerous versions of the SBC and BBC, and that Crusader for instance, has a reputation for buying the 4-bolt truck blocks, and Mercruiser had been using the 2-bolt motors for higher power ratings, and that seems backwards but that's what was going on. Don't know now what they're doing. Same with the SBC, you can get a "crate motor" and it is gauranteed to come on a crate, and that's about all. Those could be two bolt taxi motors, and certainly not the 4-bolt truck blocks that would be ideal for marine use.
the SBC (small block Chevrolet) certainly has been developed over the years. You can even get a 400 cubic inch small block and I believe those have siamesed cylinders (as do NASCAR motors). In any case a 350 4-bolt would appear to be "the choice" in Crusader form, if I were on the hunt for a smaller alternative to the big Ford or Lincoln. I dare say the newer motors with almost the power of a "detuned" 427 would make for a pretty good speed, but naturally those motors would never stand up over the years if pitted against a 427. In any case, for Dave, it may make sense to do the conversion, enjoy the boat, and then end up with something that may still be marketable when you plan to sell.
Good find Bill, excellent !
thanks, Paul
