To David's question on how much time on the 2276 engine. Just break in time by the builder. The engine came in my Speedster when I bought in 2017 with 100 miles on it. The cam was bad to start with or not broken in correctly and had 2 worn lobes. I had the engine gone through and the cam replaced and broken in correctly. I had the builder replace the piston, rings and cylinders all bearings, clean and check heads. The cost was approx. $1800.00 so I didn't actually recoup the entire $7500.00.
