Matt Hensley was freshening up and doing the upgrades to Eplings engine. At same time he was building my engine. I have seen that engine apart. What was supprising to me. Was how well that everything looked on the tare down. Which is a testament to what the GEN 3 can take. The other thing was how unexcotic it was. Good quality parts mind you. But nothing that made me say "Wow Thats Interesting". Matt and Ken Hensley are really starting to ramp up their GEN 3 program. Doing some good stuff. My next engine I do will be a Hensley GEN 3. Eplings have worked their tails off also. With the tune ups and chassis setup. They got that thing hauling for sure. They have done a awesome job.
