I would be looking to sell that block and upgrade to an aluminum block. So many wives tales exist about aluminum blocks still. Did the guy who told you the cylinder will move around also tell you that aluminum rods can only go 50 passes in a bracket motor too?
Al, this isnt my 1st rodeo. Been racing since the early 60's.
I'm going 8.30s in my little small block Dart.
I thought a good aftermarket iron block was supposed to be better and handle hp better than a aluminum block. i guess that information about cylinders moving around is a wives tale then? Then why do they say you make more hp with a iron block over aluminum?
