BTW---would you know of anyone making some 1.3 ratio break in rockers for a SBF??? I've got a set for the BBF's but can't seem to come up with any for the Windsors?????

Crower 72-884-16, 1.3:1, 7/16" studs. A man of your caliber could turn out some thin bushings to use them on a 3/8" stud.

I edited my post to include reduced ratio rockers. Thanks. Forgot about them.

Thanks Richard, never thought to check Crower!!!!! Got to get a set of them ordered!!!! I use Crower cranks in some stuff, but not their cams....

the big studs aren't a problem.... Quite sure I can get 7/16" studs in the new AFR's when I order them, anyway.... Also, with the hydraulic rollers, how much spring would you suggest for about .500 to .550 lift????

PS--busy...Looks like the cylinder head shootout is gonna be postponed til Fall......

I might be thinkin' a 325 lbs/in rate with 130-140 on the seat.

Thanks again, Richard!!!! Just ordered a set of the Crower Rockers, too. Think I'll probably still use my junk springs for run in!!! Probably not a necessity, but I have them, so why not? Whatcha think???

Oh yeah.... World Products has the Roush 180 and 200 heads available now in cast iron, their site sez aluminum will be released eventually---- Supposedly some substantial improvements in the runners and chamber.... How do you think they stack up against the AFR heads of similar CC??? I've had nothing but good luck with AFR's, but if the Roush heads is better..........

Maybe you should just come up this summer and build the dang thing for me too, huh????
