Mick i think you've done well with the barrel. i did some running out to the garage and comparing to mine from the photo's and she looks to be the goods. the de-comp is a bit of a mystery though. most people usually plug them up anyway as i have. with a decent CDI fitted, you won't need the de-comp anyway.
the exhaust manifold and head from your other barrel will bolt straight over but you'll still need to source an intake manifold and the dowels.
well done!
as for the LT1's, collectable?
hmmm, don't really know. i looked at one a while back but shy'ed away from it as i was hoping to put a 125 top end on it but found they run a different stroke to the 125/175.
if you've got a use for it, just do it.
