They dont seem to be popular with the Mopar crowd, probably for a reason... Chevy guys run them all the time. You really didnt say much about the cam, other than .700 lift. Is this a solid flat tappet with moderate 3025-350pen pressure? Or a solid or hyd roller with 500+ lbs of open pressure? Big diff between the two. I assume its a roller of sorts, cause there isnt too many .700 lift fat tappets, although I had a custom Bullet racing cam from Ray Barton for a Hemi I built. I would avoid the higher spring pressures that are required with a roller cam utilizing those rocker arms. I still like and recommend the Isky/Crane Ductile rocker arms for mild flat tappet cams for adjustable valve train. They just last for years and years. If you have a roller, I consider the Harland Sharp rockers for a entry level engine with moderate spring pressures.. One thing I have learned over the years is, there is places to skimp, or save money on a performance engine, but the valve train isnt one of them.

It's a solid roller with .705" lift with the 1.6's, I've already decided I need to buy some 1.6 Harland sharps. I bought these Cranes a while back and wanted some extra lift but I don't think I'll chance it.
Thanks for the input.

My Harland Sharps. both sets, 1.5 and 1.6 , check out at the retainer to be more ratio than advertised  My 1.5, a very old set, are actually 1.54 at the retainers and the 1.6 are also 1.65 at the retainers  Check yours first with checking springs before setting the valve springs up
