GH85,
I have a nice RV Cam (Crower 250 HDP), adjustable steel timing gear & chain set, and pushrods that you could have for $50.
I will guarantee it good, not even 10,000 miles on them.
I also have a set of what were brand new 406 casting heads with stainless steel valves and poly locks, but they wont fit a 305 block.
I also have a nice 350CI factory forged steel crank, all ready to go balanced for 1700-1800 grams rotating assembly.
I build a full roller motor, (converted a Gen-1 block using all factory parts with V-6 lifters) for my Elco 357CI with fuel injection and a 700R4.
PM me your phone number, and I will talk your ear off!
Thanks,
Dave
