looks like he was fighting a balance problem......maybe, He missed a shift.....

        or, one to many passes on those aluminum rods.....it's a mess for sure!

     We had trouble with Clevelands coming apart in drag racing also. NASCAR did too. The oiling system was not good, cranks didn't get enough oil. As memory serves the oiling was similar to the street FE's, the lifters were oiled first, then the crank. There were several built with oil piped directly to the main caps with internal lines.

     The other issue was the reduction of the crank journals so there was very little strength in the cast cranks. The Windsor bottom ends and oiling were considerably stronger. The result was "Clevors" and the aftermarket developement of better Heads.  

I couldn't help but notice that ratty looking engine in the background. The one with the weird oval air cleaner and flat valve covers. I would gladly take that off your hands for its own protection! Chuck in NH

chuck, me too, its not my photo, but one i came across as interesting,

Gary, yes ford here in Australia did cast the clevelands a little better, in 70.71 there were the all blue colored ones fitted in the 70/72 GT falcons, some had 4MA cranks that were tuff, the actual 71/72 GTHO falcon had a huge front balancer, huge 4V cyl heads that you put your hand in the ports and many variations of things, i cant remember them all now but were the stronger engines of them all, then came the blue engine with orange v/covers, aussie built and ok, the big improvement for the street was the 2V heads that made them popular in the US, a mate sent a pallet load over there for engine guy. then came later  black blocks mid 80,s and had larger distributor oil pump drive outer shaft size. You could write a book on all the differences but i have forgotton most. I had Std bore 351,40/80 solid lifter cam,750 DP holley, tricked C4, 4.86 rear in my street driven 72 XY falcon that ran 12.00 at the drags in the 80,s. An aussie guy realised the 4V heads were Too big for street and 2V too small so ported the 2V and fitted 4 V valves thus the 3 valve tag came, it was most suited for street racing. Now of course there are numerous aftermarket alloy heads.

I dont believe there is a book as such, we only had 272,s here ( australia) till the 292 arrived in the 59 f600 trucks and ended in 64. We had the 239 flathead, 272,292 ohv, 260/289 in the 62-64 compact fairlanes, 332. in the 59/.61 tank f/lanes, 390 + 289 in 64 galaxies, 390 in gals from 64-71, 400m in 72 gal. 289/302 w in falcons 67/71, 303/351 Clev in 71/80,s falcon. i might be bit out on dates but near enough. There are very little records on anything here. Argentina had the phs1/11 y blocks. We had phs1. phs11, phs 111 falcon GT,S.  best regards bill.
