which roller rockers to buy?
Tried to do a search, no luck.
motor's my 67 mustang
302 - 9.2 compression
hyrdualic flat tappetcam .448/.472 lift with adv 280/290 duration
204/214 duration @ .050 Lobe Centerline 112
E7TE Heads
I'm wondering if there is any real difference in the brands and what you guys have used or recommend using. Going to buy fully rollerized probably aluminuim. Looking fornot much more than $200.daily driver. Should I go 1.7 ratio? Will this hurt low end torque at all? How much HP can I expect to gain? thanks guys, and if this has already been covered, my bad, just point me to the old posts

I'd get crane pedistal mount rockers. 1.7's are probably gonna be over kill on e7 heads. I'd get plain 1.6's, that way you don't have to recheck piston to valve clearance.

what kinda valve springs you have? if they are stock and you plan on keeping them that way, you'll be needing 1.6's. otherwise 1.7's wouldn't be too bad and i highly doubt you will have PTV issues
