At the, as we always knew it as, "Turkey-Rod-Run" in Daytona last weekend (they call it something else now),...........drum roll please!........... how about an aluminum intake manifold for the Studebaker 299/304.5 cu. in. "R3" supercharged engine! And the vendor stated that after an exhaustive search he had not been successful in determining what it fit, ............but I know!
Now you won't find one of these everyday, as Andy Granatelli who had purchased Paxton from McCulloch and then Studebaker bought them, but didn't survive long after, so few "R3" engines were ever installed in any cars (perhaps something like nine Avantis and couple of Larks is the count) and post Studebaker involvement, there was an undetermined number of engines and parts sold off by Granatelli, but perhaps something around one hundred plus or minus total in different states of completeness.
So now, for my 289 (no, not A Ford 289!) all I need is the "R3"/"R4" exhaust manifolds; the search continues!
BTW, the Studebaker Avanti "R3" was "officially" the fastest (170+ M.P.H.) American production car at the time!
O.K, since this is the FE Forum, not as rare, but I did pickup a '64 410 block, the one with the extra web and cross-bolt bosses, std. bore, nice shape, destined for some high- revving 390 or something project w/ cross-bolt caps installed. And, a 9 inch "N" case w/ "Daytona" support too.
