Hughes cam?

If the 225 is grossly under-valved as claimed in post #35, then a 102-ish LSA as mentioned previously is a good idea. Use duration to control power range, idle quality.
If you think 102 is tight, Jon Kaase, multiple EMC winner, used a 98 LSA cam with 92 ICL to win the contest with a 400 Ford engine that made 660 hp with a broad tq curve & a cam that was not that huge in duration.
I think the post you're referring to said 102 ICL (intake center line). ICL is different than LSA (lobe separation angle) I think. I agree with your premise (tighter LSA is better for under-valved engines), but is there a company that would even grind a /6 cam on a 102 LSA (and be able to get it to me by end of May)? Not sure if a regrind can take a 108 LSA all the way down to 102 - that's a pretty big change.
