DIY LTCC or similar system for LT1s

[spfautsch]

FWIW the LS1 engines DO have overlap. It just happens to be at lower valve lifts than the LT.

Valve overlap is purely a function of cam timing (lobe separation angle), duration, and lobe ramp rates. You and Tom B should take your LS vs LT p###ng contest elsewhere, it's not contributing to the essence of what the OP is trying to accomplish, which is cooler than you're capable of comprehending.

vilefly: - killer idea. I can't wait to see how it pans out.
