Motor Question

93CougarXR7 · 04-26-2002, 06:26 AM

I have a 5.0 in a 93 XR7 and am thinking of a cam swap. I have a cam with these specs--
lobe lift- .322" int/exh
lobe sep-110 deg.
2.06 deg adv
252 deg dur @ .020
221 deg dur @ .050
133 deg dur @ .200

The motor has a stock bottom end, iron pocket ported heads, stock gasket matched intake and exhaust, 3.55 gears and the low gear AOD kit in the trans. Is this a decent cam to put in? I am worried about piston to valve clearance with the stock set-up. I also have 1.7 rockers available- can and should I use them? Any other suggestions would be a great help. Thanks..............

He's talking lobe lift, you're talking valve lift. With 1.6 rockers, he's got a valve lift of .515", which won't have any clearance problems.

Take care,

my mistake, you can safely go up to 530 VALVE LIFT right?

Thanks for the info guys. Do you think this is a decent cam for a street/strip car? I got it at a good price(free) but don't want to do through all the hassle to change it if it will be junk. Thanks again.............
