Yeah, I talked with a guy years back who did motor buildups on that 4.3
V6(can't recall his name). I was considering a hotter motor for mine. He
lives just outside Detroit and was involved with the original
development for the Sy/Ty program. They did several variations of the
motor from mild to wild before settling on the one they used.
Seems there was much wrangling internally and the guys who really wanted
the hot rod truck did hide some things. More than once he did some late
night visits to the Dyno room to remove some "mistakes". Some of the
stories were hilarious. There was the one where the thing got so hot
that it kept running up until they disconnected the fuel flow. Exploding
motors imbedding parts into the wall. Many a hand grenade job including
one that blew the two front cylinders completely off the block! How much
of it was true is anyone's guess, but it would support the hidden
development idea.
