tbarcelo,
Primarily, it's a head design issue as afr as selection. A lot avoid ths a go with ally heads, expensive, but will flow like a big block with the right gear for it.
Over the past years I've collected a SeaLand container full of 351w's that I've slowly been going thru vating, align boring, boring, TRW's pistons, polishing the cranks, basic balancing, and just good assembly to arrive at a basic 351W for under $1500.00 each. Just takes a little patience and time. Above all don't rush you're COBRA, treat it like an investment. For a daily driver, go the donor route, it's just a matter choice. I tend to lean the way of the originals of the 60's, be it a Grandsport, Lister, Cobra, or any of the cars of that era. State of the art electronics, EFI, 6 speed trannies, and so on I'll leave to the younger set.
