You have some phone numbers so I can call and ask for pricing?I know of a few race shop i trust in central/south central PA. Had my 15 Sho done by a performance shop for an engine swap and modding it just under 2 years ago. Another shop custom built me a flatplane crank, assemble and dyno for my gm big block.
I know of some good places on the east coast.
Actually my neighbor owns a tow company and a race engine shop and across the street from me is a race engine shop. Down the street is Lincoln Speedway so these shops within a mile from me mostly do 358 and 410/Outlaw sprint engines. Not sure what other projects they would do though
I want to know how similar manufacturers use cam and bucket setups that go their whole life without ever being adjusted. IIRC certain toyotas had that setup except you change buckets instead of shims if you want another size.Ive built plenty of engines so im sure the yamaha sho engine isnt any harder than a normal engine. It just has nickels in the valve train for some reason.
I actually wish more engine used the nickel system, all/most of the valvetrain wear is given to the middleman (the nickel) and its not hard to do every 60k miles or so.
Keeps the lash good. Shim over/under bucket design, im a believer in it.
