PERFORMANCE ENGINES I have for many years avoided becoming a "speed shop," not that I'm going to become one now. And not that they are bad or anything like that, I'm just not a race guy. I'm more about working with the car clubs and LBC enthusiasts that want to keep their car on the road and running well. In the past, I just wanted to be good at rebuilding a solid, durable and dependable engine that could be driven on the street, on regular 87 or 89 octane fuel. But now I am satisfied by the work I've done and want to reach out to a new line of engine work. GOALS More power and responsiveness without sacrificing durability. Who doesn't want more power? I want to build an engine with more power for passing and a quicker climb to highway speeds. I want an engine that will work well with a 5-speed gearbox or an overdrive for high speed ranges for interstate driving. THE WORK IN PROGRESS I have completed the building and testing process and have decided on a standard performance build. When I have an engine with a TKC2748 head I will build that engine just like the 76 Spitfire/MG Midget engine that had 9.0:1 compression, which has decent performance but I will add a B270 cam from British Parts Northwest or my similar JMAC 270 reground cam for better valve lift. When I have an engine with a low compression head such as a TKC3239, TKC1409 or a TKC1410, I will convert that head to be similar to the TKC1156 head with the exception of a larger intake valve (1.43 diameter). This head had a chamber volume of 37cc and with the flat pistons produced 9.6:1 compression. Couple this with the B270 cam from British Parts Northwest or my JMAC 270 reground cam I have a solid high performance engine for road use. The testing on these to designs has gone very well. I had one 9.0 compression engine and one 9.6 compression engine in the process of building when they both sold before completing. Check out my "For Sale" page regularly! All of my rebuilds are built using the guidelines laid out in JMAC ENGINE REBUILDING PROCESS. CONTACT ME if you would like me to rebuild your engine to one of these guidelines. COMMENTS: I welcome your ideas, concerns, and advice. Everything I am going to do here has been done before, some with great success and others complete failures. I would like to know what you think.

SOMETHING ELSE THAT IS NEW AT JMAC ENGINE SHOP! I have completed my new engine test stand. I have been using it to test all my rebuilt engines. It works great! I can run an engine at a various speeds for hours, if needed. I don't have a way to add load to the engine yet but eventually, I will be able to add load in the form of a 30K watt generator. I can now test a variety of engine sizes since it is fully adjustable. Here is a video done on an engine I was testing for a local guy (not one of my rebuilds). www.youtube.com/watch?v=QSVclvoc0CQ&t=1s
