I have never had a perf cam set up at less than 0.015" int and 0.022" exh lash. IIRC, that OCG 346 runs best (hot idle stability and vacuum close to that of near-cold numbers) at around 0.020" int and 0.026" exh.

I wish I had more data/ideas about ramp and adv dur for you, but I don't...

If you think your Offy 2x1 intake will be the choke point for your build, have you considered modifying it for a 2x2 setup?

I have seen guys put a pair of BBDs on that intake too.
You guys are a terrible influence in the best possible way. :lol: I do have a shiny pair of BBDs in the basement, and I'd bought them with this in mind, but... I think I'll stick to 2x1bbl for now. Using that with the 346 will simplify the project a little, and I can always make additional changes later.

I ordered COMP Cams 901-16 springs and 744-12 retainers.

Question: Is "#346 with 110-degree LSA," all the information OCG will need?

Ask OCG to grind with a 110 LSA and, if possible, can they grind it with 104 intake centerline. 106 CL would also work well I'm sure.

Best,
Lou
