I looked in the comp cams book and the pushrods have the same part# for solid or hydraulic so I'm assuming they are the same.I have guideplates and screw in studs.Anything else I need to change or do?------------------

All I can think of is tall valve covers and roller-rockers.
Good gaskets because you will need to remove and reuse them.
If your covers don't have a baffle be sure you use the correct grommets to prevent excess oil consumption. You'd be amazed at how much oil you can suck up the PCV valve.
Let us know how you like the new cam. I run a 282S and it is enough for me for the street.Joe Joe

The 282S is not as big as the 292H. It should give you a nice seat-of-the-pants improvement.  ------------------

Mustangboy,My car is a 65 Fastback. 289 with stock/ported heads 1.90&1.60 valves. Compression probably a little over 9to1. TRW flat-top pistons.Performer RPM. Carter 625 carb. Headers and glass-packs. 3.89 rear. Toploader BUT close-ratio.
My car is pretty light. The tall first gear, in my CR tranny, is the only thing I don't really like.
The cam is just what I had hoped for with my light car. I can let it get under 2000RPM in fourth and it will pull away with no real trouble but there ain't a lot of power there. It revs past 6500 easily.
Has a nice idle, not too rough, but I don't have any vacuum equipment so I don't know how it works for that.
Power doesn't really begin until over 3000 and that is where it runs at 60 MPH in my car.
I have about 30,000 miles on this engine and it is as tight as it was to begin with. No oil consumption. Never pings. I run 14 degrees initial advance and 38 total.
I like the cam and love the sound of solid lifters.
IF...my car still had all the weight of a stocker AND was used a lot on the street, I'd step-down to the next cam AND use a hydraulic. Just easier to live with everyday and still good power. If you won't race it I'd go down for sure. The power will be where you really need it.
I just added this part after seeing that you have 4.11 gears. The 282 should work, even if the car has all the weight of original. Just be wary if you run any vacuum equipment from what I have heard. Good luck,
Joe [This message has been edited by JoeD1860 (edited 03-26-2003).]

I have no vacuum stuff to worry about.This is actually a little smaller cam than I'm running now.Car wieghed 3150 when I got it and I've probably removed at least 50lbs of air conditioning stuff(compressor,brackets,heat exchanger).I'm trying to get the car into the low 13s.Although a 13.69 was my best, the car was always run on real hot humid days so I think it may have been a 13.50 car or so in decent weather.I'm hoping the cam will help with my 2.0s 60fts.------------------

In that case I think you will like the 282S cam.
Let us know how it does when you do get it running, no matter which cam you select.Joe
