cam suggestions
I dont know if this should be posted here or Power Adder, but it seems power adder is mostly NOS,Superchargers and stuff.I have a 1990 5.7 TPI,700 R-4 auto.I am about to install the longtube Hedman headers,Holley AFPR and probably the Mufflex 4inch exhaust(no cat)or at least the 3 inch American Thunder.Also I am going to port the plenum,I cant afford a new intake at this time with all of this other stuff but I would like to change the cam.I need to know wich cam would be the best to get without it affecting the stock computer(Hypertech chip, big deal ) I was looking at the Saturday Night Special Cams & kits in the Jegs catalog.But I dont know crap about cams!I am pretty mechanically inclined so I believe that I can install it with a little "tech support" here on the boards.Any suggestions on what I should get would be greatly appreciated,including part #'s,duration and lift and anything else I need to know.Including some installation tips,like I said,I dont know crap about cams,but have done all of the maintenance on my car.I drive it to work and back but that is about it except for drag racing at the track because I have a daily driver for family use.I am looking to spend about $250.THANX in advance for any help!

If you don't plan on any other mods(heads, induction,etc), go with something like comp cams 08-501-8 xr264hr 264 269 advertised duration, 212 218 @ .50 duration, .488 .495 lift, and a 112 lobe separation angle, advance the cam 4 degrees for a little more hp.

Just remember that you are going to have to have the valve guides cut down for anything over around .470 lift. The machine shop I took my heads too, said the seals would start to get hit at this number. I am sure some people have run more, this just what I have seen personally. You will also have coil bind problems around that sam enumber.

I dont plan on doing any head mods(or valve)at this point.I just want to be able to put something in there using my stock valvetrain.If I have to change the lifters that is alright and maybe the springs, but I want to use stock height valve covers.Thanx.
