quote T-GRRR:

I’ve been running a Crower grind number 285R solid-lifter roller-tappet for about 15 yrs. Adv duration int/exh 285/292 … duration at .050 254/260 … lift .597/.578 … 106 deg lobe separation. Makes great power even at low rpm all the way past 7500. Will idle down to 900 rpm but that’s with individual runner induction. Used with Comp Cams Pro Magnum roller rockers on iron headed 322 cu in stroker.

Wow – thanks for all the info. Here is what I am likely going to use, based on the Edelbrock reps suggestion. As I said in the earlier post, he knows the Tigers and has helped other tiger owners in the past.

Edelbrock EDL 5022 214/224 duration @ .050 .472.,496 lift
Power range from 2500-6500 a bit of a rough idle

An alternative would be the Summit 3601. Power range from 2000-4500
218/228 duration .471/.471 lift. A bit milder cam and a lot milder price.
