Re: Anyone got the lowdown on Hesco?

I agree with you Tom, but no one was doing it. The 4.0L looks so much different than a 258 at first glance that I don't know if anyoen thought about checking the bottom ends. More likely it's that the 4.0L didn't come out until 1987, and few people will tear a new engine down and experiment with figuring out the combo to stroke it except racers. Average hobbyist would look at that come rebuild time, maybe after warranty ran out. So that would be in the early 90s. Very few people knew about the big bore Mexican block that came out in the mid 70s though. That would be a better conclusion. I have no doubt that HESCO was running Mexican block race engines well before AMC was thinking along the lines of the 4.0L. HESCO didn't destroke the engines like AMc did though, they made them bigger! AMC went with the shorter stroke/bigger bore to get a bit peppier performance, something a bit more comparable to everyone elses V-6 engines.
