I also have a 305 chev engine that would need a complete overhaul
to use again.. Personally I think I will carry it to the junk yard next
time I get a load of scrap iron..Had a 305 in a Trans Am once and did
not think much of it..You could probably buy a good running 350 for
the same price that you would spend on rebuilding the 305, and you
would have a better engine...I think the headson a 305 are no good,
so you most definitely would want to change them out if you stay with
that engine. I'm sure the pros can give you better advice than myself,
this is just me thinking.
