Luke,
The engine is out of a Brazilian built Uirapuru, a sports car using a truck engine, it was originally equipped with tube headders and 3 SU carbs. They will be kept there. So no need to worry about it! Anyway, quite cool suggestion.
Sixpack,
Brazil is the sotebolters paradise. 261 were available brand new up to 1976 (and as incredible as it may sound, the 292 **** Y block also made it to 1976 - we only lost to canada, were the flathead V8 went to 1980) in many commercial vehicles, then were supersseded by the 250 and 292. Long time ago we discussed the modifications using 292 pistons/rods and stroking, and as I recall, Chevyman remembered quite well that the narrower 292 rod would not provide enough side trust for the rod, and that would it'd be no good. So by that time I quit the idea of stroking in, although it is possible just to bore it all out to 3 7/8 using just the 292 pistons.
By the way, all the machining is over now, decked it to get a zero deck situation. The only doubt by now are the rods. I'll go to a big engine shop tomorrow and will try to spot a set of boltless rods for the 261, they were available here, virtualy identical to the normal rod, just no bolt to tight. Assemble just heating it as well as any other press fit rod.
Just for your information, down here we have even a 250 L6 with EFI, multi point sequencial fuel injection. Go figure! And try talking here about chevrolet V8, most guys do not even thing they do exist! They have never being brought here by Chevy or GMC.

Guess the boltless is lighter. If I find it, will pick the whole set.
