    Stock pump is like 85 lph or something, nothing really fantastic. Its enough to do an HO but there isn't a lot of head room. If its 20 years old, its probably just a good idea to swap it for a newer one just to be safe.

    The stock boring Ford cams work well with speed-density, can make plenty of power with good supporting parts, and are dirt cheap. They also tend to make for reasonable fuel economy. If you really want a torque monster cam, the Comp XE-258 sounds like an awesome cam for a heavy car and/or towing applications, but its got more lift than stock. There may be clearance problems with the stock pistons since they have no valve reliefs.

    Actually those GT40x heads you'd probably want to check the clearance just to be safe.

      Adjustable regulators don't really work... ECM learns around them.

      No matter what you run, SD or MAF, to get everything out of it, you really need a tune. I cannot believe what I have gotten with the little bit of tuning with the TwEECer on my wagon.

        Whoa,
        They're the 58cc chamber, I didn't realize there were no valve reliefs, I have only played w/H.O.'s in the past..... this could jam the brakes on the whole project.....

        I've heard of the TwEECer, this bears investigation for both the wagon project & the race car....

          combustion camber size has nothing to do with piston to valve contact. valve size, gross valve lift and valve springs will dictate how much clearence you have. usually the rule of thumb is .500" of valve lift with the stock, lopo pistons.

          1.7 rocker arms will add .030" of lift at the valve to the cam you are using. HO cam has an advertised lift of .444", adding 1.7 rocker arms increases that to .474". explorer cam has slightly less advertised lift.

          as long as you stay conservative with the cam and use a good valve spring, I don't think there will be a problem. however, it's always a good idea to use clay and check the clearence before you put the motor together.

            It was more the valve size that I was thinking of as being a possible problem. You might be fine as long as you don't go radical with the cam. They're not huge so it might be ok.

              Based on previous comments, & a discussion w/a tech advisor @ FRPP, I am beginning to think it might be better to sell the engine whole & do a cheapie rebuild on an H.O. that I have on the shelf....

              I would hate to tear a good reliable engine down & find out that there is not enough clearance......

              Any body know what an 87 CV engine is worth?

              It uses no oil or coolant, makes no funny noises, I would not hesitate to drive it anywhere.....

              I have confirmation from the previous owner (a Ford technician) that it is a roller.

              It bone stock & has been meticulously maintained.......

                oops, my mistake, it is not bone stock, it has a replacement water pump, oil pump & double roller timing chain.....

                  ALL 5.0L EFI passenger car engines, 86 and newer are hydraulic roller cam. ALL hydraulic roller cam engines got double roller chains.

                  all the car 85 and up 5.0L blocks are essentially the same. the difference between HO and non-HO is heads, cam and pistons.

                  honestly the GT40X heads shouldnt make much difference. Like I said, as long as you stay conservative on the cam and use good springs, I doubt there will be any P to V contact.
                  Several guys on coolcats.net are running FRPP E303 cams on stock non-HO short blocks with no problems.

                    This project has been going alot slower than I could have imagined.....
                    After the oil pump shaft fiasco,

                    http://www.grandmarq.net/vb/showthread.php?t=25994

                    I didn't have much time to work on it since then.

                    Then I found that the piston to valve clearance was only .050. So, I bought thicker gaskets & installed the heads only to realize that to properly install the new pump shaft, I have to pull the pan any way......

                      Basically, well 200 tops, you can get an HO or exploder for 500 or less. Not really worth much because of the power. Only thing they make good replacements for is other panthers and some trucks. I gave mine away...

                            Really? Every single one of my panthers 87-91 had double rollers from the factory.

                              Weirdness ... must've been one of those hit-or-miss things that was influenced by what the engine-plant boss got cheap at the local Mega-Lo-Mart or rebuilder's surplus store? I tend to go by the fact that the two Panther motors I've torn down (granted, a very small sampling) most certainly had nylon teeth, and that I seem to distinctly recall a few GMNers complaining and/or postulating about wiped cam sprocket teeth, which shouldn't happen with a solid gear.

                                I've seen engines with 1989 date code single roller chains. My 86 motor had a double, and every other SEFI motor I've seen apart had double rollers. My 91 LSC has a double roller. I just took it off.
