When you think of high performance, it’s easy to get caught up in the excitement of pistons and power adders. However, when you’re thinking of upgrading your engine, your FIRST thought should be about your bottom end.

A rock-solid bottom end will ensure that, no matter what you add, the engine will most likely stay together. Of course, you can go TOO far and then no amount of prep will save the engine, but that’s a topic for another day.

In this LiveStream, experts from Tomorrow’s Technician and Summit Racing explained just what makes up the bottom end of the engine block – the crankshaft, main bearings, connecting rod bearings and main caps as well as the importance of the proper fasteners, hardware and oil pan for your needs.
