I'm running a comp cam Hi energy 264 roller, and gotta say it is an awesome street cam, idles low and smooth. 274 is better but sacrafice some idle joy.

I'm running this Comp Cam: http://www.summitracing.com/parts/CCA-35-308-8/

It's the Magnum cam that's one smaller than the one you are looking at. It idles smooth and makes a bunch of low end torque. You'd be happy with the one you picked as it would make a bit more top end power than the one I'm running.

I've talked with Summit and Comp.  Summit came up with these: 35-310-8, 35-308-8, 35-351-8  http://www.summitracing.com/compare.aspx , but talking with them the second time the guy said to stay under 0.500 lift with my engine/head combo, there may not be enough clearance.  Also he said the 35-512-8 cam or E303 would work with a stock converter.  Who's right?

I have no clearance issues with GT40P heads, 1.6 rockers, and stock HO replacement pistons. The Comp 35-308-8 I'm running has .533 lift on the intake and exhaust. Clearance issues usually come into play with long durration, high lift cams. The 35-308-8 is a low durration, high lift cam. I believe the other Comp cams you listed are the same way.

Remove everything down to the long block, and swap on everything from a Fox 5.o....

-Fox oil pan
-Fox headers (I used BBK unequal length shorties with Taylor wires and 90 degree plug boots...zero problems)
-Fox timing cover
-Fox water pump
-Fox accessories and brackets
-valve cover (although you can use the ugly Explorer covers if you choose)
-install a distributor
-Fox harmonic balancer
-Fox oil pick-up
-threaded adapter that the oil filter screws on to
-valve springs
-drill and tap a hole into the number 5 runner for the Air temp sensor
-keep the Explorer injectors
-Mod the t-body to work for the Fox chassis (takes about 5 minutes using a stock Fox body t-body throttle lever)
-Fox body throttle body spacer (65mm to match the upper intake and throttle body)
-install the water pipes on the lower intake
-Fox fuel rails
-You can keep the Explorer thermostat housing
-Fox IAC
-Fox sensors on the lower intake
-May have to cap some holes in the lower
-

Take care to remove all of the Explorer parts intact and sell them as new on Ebay. You can make some bucks from them

 
What would be the down side of using the Explorer accessories, except the oil pan, Alt, water pump, power steering, A/C comp.

Motor is installed and I fired it up a couple times. Seems to have a hard time keeping an idle at first.  I unplugged the IAC while running and nothing happend.  Also top end is ticking, maybe I need to adjust my rocker arms some more,  pics to come later.

If the engine has been sitting for a long time or has never been run it might tap for awhile. Did you prime the oil. Depending on the assembly lube if it sits for a long time it can harden and cause alot of problems with oil pressure, valve tapping, and oil drane clogs. With the valve tap, that could be caused by clogged lifters.

correct, and long duration cams are recommended for higher compression builds.. i ran a .554 lift/.272 duration cam with GT40P's (decked .003 for a slight compression bump) and stock HO pistons with no clearance problems.. tried a .532 lift/.290 duration cam and it was really, REALLY close to the PTV tollerance

The down side would be having to mod all the lines...a/c, steering, etc. All the Fox stuff is a direct bolt on.If you're swapping to a decent cam, it all has to come off anyway.

I primed the system with the motor still on the stand just to verify oil circulation.  I primed it again before starting it.  It looks like my ISC is working, no engine codes.

Ok Vinnietbird, thanks for the heads up. The plan is to have the engine compartment as slick as possible so I will be using custom made stainless hoses for the A/C and fuel and since I don't have any of the Fox stuff I will give it a try and see what happens. Do you know anyone that has used the Explorer accessories?
