I've never seen an aluminum 302 block, was curious if it was a massed production thing, or as he says a rare ford motorsports item. And does this seem like a good price for one?

Bruce,
are you guessing that they'd be ruined or do you know that first-hand??? If that's true, how do motorcycle and snowmobile engine blocks withstand water splashes and even being submerged in water without any evident ill effects? Are they made from better or different aluminum alloy material? Ryan

351 SVO block that's been severely decked (by an inch or more) and
is being passed off as a 302 block. The K351 part number is a 351
aluminum block p/n. The 302 aluminum race blocks have a 302 in the
part number. M-6010-F302 is the current part number for a FRPP
aluminum 302 block. The mains still appear small enough that it
could be finished to a 302 main, however but the width of the oil
pan rails tell the tale. Here's what that block is supposed to look like: http://fastfords.net/cobra/engine/block.htm > And does this seem like a good price for one? Not if you figure the sort of machine work that's left on the block.
Looks like a number of machine features are missing. > are you guessing that they'd be ruined or do you know that first-hand??? Running through a water puddle would have no effect on it. There are
lots of aluminum V8's in service and they work just fine. I've got
one on an engine stand that has 160,000 miles on it in all types of
weather. It was still going strong until the drones at the oil
change place forgot to tighten the oil filter down and it lost all
its oil. I also have an aluminum V8 in a Triumph TR8 with 52,000
miles. > Are they made from better or different aluminum alloy material? The usual alloy is Reynolds 356 with a T6 or T7 heat treatment.
The casting method makes a difference. Some are sand cast, others
are die cast. The old aluminum Buick V8's were die cast 356-T6.
Their Rover aluminum V8 descendents were sand cast. The Fontana
Cleveland/Windsor hybrid block is also 356-T6. The F302 is 356-T7. Dan Jones

> How much would a alloy 351 windsor block cost me? I don't have a FRPP pricelist handy but, a few years back, Fontana
dropped his price to $3800 to compete with the (then new) Ford
Motorsport blocks. The Dart blocks might be a bit cheaper. > saw the other day where DART is now making an aluminum small block Ford
> that is capable of 450 cubic inches......(yowzaaa) Fontana and Ford (via RDI) do as well. Dan Jones
