Thanks yet again guys. Fang, that was an interesting article and an informative website as well. I’m going to go through that exercise just for the experience as well as the information I’ll gain. Although, after hearing that Eric had no issues with the engine he describes I doubt I’ll have any issues. I don’t plan to have anywhere near the lift or duration he did. Tech, you mentioned a modest cam with no more than 240-250 intake duration. Is that at .050”?
I did the math for the fun of it (retired engineer). At 5° before or after TDC the piston is just under .009” below TDC, at 10° it’s about .035” and at 15° it’s .077” below.
