Strength wise,probably the same. The Dart block is a true Windsor block beefed up in the needed places, the Ford BOSS block is a combo of the old Cleveland block and Windsor block...
With a Dart block, you use all the "standard" Windsor things like head/intake gaskets, head bolts/studs and such.
With the Ford BOSS block, you must use a specail head gasket ($$$$) you have to order a right and left side, same with head bolts/studs.......if your using Windsor heads, you must drill steam holes in your heads to match that of the BOSS block....
The only thing I like on the BOSS block over the Dart block is the screw-in freeze plugs and screw-in,o-ringed
oil galley plugs...
I have a BOSS block, but if I had to do it over again, Dart all the way...
BTW: Unless you own a NASCAR or NHRA team, don't bother calling the Ford tech line and asking them something about the blocks/engines......
BTW 2: My BOSS block leaked
oil out the rear main seal from day one, tried 4 seals,3 different brands, same thing, once the
oil warmed up to about 120 degrees,it started leaking....
Called Ford,had to crate the bare block up and ship it to them in Michigan,they checked it out and said nothing was wrong,sent it back, I re-assembled the engine, same story...had a machinest check the block, the rear of the block where the rear main seal fits was machined .050 out!!!!!!!!!!!!! Ford says it's fine!!!!!!!!!!!!
