It's been so long since I did any hydraulic flat tappets but the old Ultradynes were great lobes for making broad torque, I think (hope) Bullet still has the masters and still grinds them. There used to be an old Lunati cam that was like 218 @ 050 cut on 108 I put in my buddy's old "318" warlock truck that ran really well too,

I've heard great things about Howard's and it seems they are one of the only major grinders that has off-the-shelf hydraulics on anything tighter than 110.

Something like this HOWARDS would be good off the shelf...but I'd prefer to see like a 213 @ 050 single pattern (for your lower compression)

The old Comp 260H was i think 210 or 212 @.050, and they were pretty good at waking up any mild smallblock , i think they were cut on 110 spreads. I don't really like the clater the newer XE grinds made in mopars but the old ones seemed fine.
