I am selling a 393" Cleveland stroker built by Tom Klein (Klein Engines) with a unique serial #1213 that he would be able to reference. I have his documentation and build sheet. Built with ALL NEW parts excluding the block, cylinder heads, intake manifold and timing cover. Block and heads were professionally reconditioned to the highest possible degree of mechanical tolerances. Even the oil drain-back hole in the lifter valley was smoothed out. The intake manifold was professionally ported and flowed (using a flow bench that Klein bought from Louie Unser's shop) with the cylinder heads for maximum performance. Dyno time only on engine. All in with dyno setup etc. engine cost $15,500 when built, asking $9,500 ono. The engine is not yet specifically setup for a Pantera, but was going to be installed in my '74 when I was planning to build a Group 4 replica race car. I have moved on from that plan since starting open wheel racing and don't have time for all the projects.

Apologies for poor quality photos as engine is in a crate in back of the garage, I will drag out and take additional photos for serious inquiries, but it looks much the same as any engine on the outside, it's what's inside that counts!.
