The Buick 215 aliminium V8 I would say was obsolete. On the other hand, the Range Rover (Rover) V8 is still common.Just going off the cuff here, but I think you would end up with a powerplant that is closer to a Lyc 540 in weight, yet has the power output closer to a Lyc 360. Throw in the Buick's rarity, and you would be much better off going with one of the more modern all alloy V-8's.

Amazing! An aluminum GM 4.3 V6 short block from GM racing is about $5,000.Not even close. A block is a grand brand new from GM; You can buy an entire stroker shortblock from some custom shops for around $5 k; and the entire engine "complete" can be had from GM for under $6k.
Direct drive? Please tell me more!Update to my prior post. The Factory LS-3/L-92 block has gone up in price from the last time I checked and now retails for $1,700, but nobody pays retail. They can be had for less than $1500 with a little digging (and sometimes a lot less). Even so, the fact that shops are puting together brand new 415 inch stroker short blocks and selling them for $5k (presumably at a profit) tells me that these are cheap engines to assemble.
One of these $5k stroker engines would be an excellent basis for an aircraft engine because it comes without a camshaft and heads - the two "aircraft unique" items that you would want to do yourself. The heads would be simple small port Vortec heads (which can be had used for about $75 bucks per pair), and the camshaft would be the only truly custom part - which can be custom ground for $500 or so. Throw a stand alone ignition unit ($275) and a Bendix fuel injection system ($500 - $3,000) at it and you are well on your way towards a 300HP direct drive aircraft engine.
