    What are the tolerances on the cam profiles? Could it be that these variations are just variations within tolerance from the factory? ...and the only way to get a hotter cam (aside from aftermarket or regrind) from the J/Y is to measure each individual one and compare it to the one you already have?

    i always though that the Magic cam was just a myth.. didnt make any sense, but yeah it was a missprint in the manual.. some guy from escort underground took 2 91 cams and a 94 cam to amchine chop and had them measured out... all the same

    theyre kinda sposed to be the same... the issue came up when 3 different manuals, one of which is the Ford service man. stated different numbers..

    and to only make it worse, real world measurments show some 91 cams to have a few thousandths of an inch larger lobe lift.

    I always thought the 1.9HO cam was the desired choice but needed to be retrofitted to the 2nd gen head. probobly completely wrong as im new to the sohc game and didnt read pages 2-13 lol.

    I don't remember who posted this link but came accross it about a month or so ago. Supposed to be100% new cams for alot less then a regrind.

    http://www.iskycams.com/makesearch.php? ... ine_id=290

    I was thinking of going with isky but not sure if the duration will be time correctly. To me the cheaper the cam the less research done for the best performance. Granted piper and kent both make CVH cams, make sure if you go with one of those that you get a fuel injection cam and not a carb for the best performance.

    If any of you are looking for E-spec parts try these couple of links.

    www.larkspeed.com
    https://www.burtonpower.com/default.aspx

    I have more links somewhere I think, will just have to take the time to find the rest, and which comp they are on.
    I hope this info helps.

    Crane used to grind roller cam billets until they ran out of stock. They currently still produce cams that use a hydryalic flat tappet lifter/rocker assembly.

    I got to wondering if Crane could regrind a stock SPI cam to reduce the cam base circle and increase the (net) lift to about 0.420". The duration would work out to whatever it came to but would be better than the OEM 186/189 deg @ 0.050". The OEM hydraulic roller lifters should be able to pick up the slack from the smaller base circle (which would be a 0.020" change in diameter depending how much you planned to grind from the peak of the cam lobe.)

    It's not clear that the Isky cam is based on a 1st gen or 2nd gen cam, but if they could regrind a 2nd or 3rd generation roller cam, that might be worth checking.

    At one time I was looking into a Crane profile that would have given me 198/198 deg @ 0.050" with 0.419" max lift. What I really want is about 205 deg @ 0.050" duration and lift around 0.424". It might be a good combination for the street with my '97 SPI.

    I was looking in the local "U Pull It" today and found a 1991 Escort Pony 1.9L Auto. As soon as I get the chance to buy a new 13mm socket, I'm going up there and pulling the head and cam to take a look. I'm going to get the cam and have it measured to see if there is any real difference.

    Supposedly, the 91 Escort 1.9L is a HP engine. I saw it while looking up stuff at Autozone. We noticed it on the computer when we pulled the combo up, and the manager said that the HP denoted a high performance version. So, this may not be total urban legend.

    When I pull the head, look at the piston tops, and get the cam, I'll post pictures as soon as I can.

    It's amazing some of the little details that many places overlook such as the TX and TK transmission codes and this quirk.

    Hopefully, switching the cam, lifters, springs, and valves over won't run too high of a risk for bent valves or damaged pistons.

    i just might, because everyone here has been jacking off for the past two and a half years on this.. and i'm still building my turbo motor and feel like kicking that general rule in the a$$, that you cant have a higher lift cam w/ turbo (w/ less n/a comp ratio you want that higher lift) so we shall see, b!tches. make me do all the fu<king work.

    WOW that long they've been trying to decide this wow I would've given up a looooong time ago. But I guess it only takes one to make a difference. Thanks for volunteering

    someone has to, because these cars aren't getting newer.. and there is still a lot to be proven to the racing community about the CVH.
    guys over in uk are running over 300whp 300ftlb on the stock 1.6 bottom end(non-bored), and still finding tweaks.
    we have a much stronger bottom end then they do. in fact, they IMPORT OUR 1.9 2nd GEN BOTTOMEND TO USE as a stroker upgrade!!
    Not to mention the spi crank is basically a zetec crank, and takes a hell of a lot more power than the 1.9 crank with double the counter weights.

    time to do some work b!tches! time to show these uk peeps how americans make big power! what are you going to contribute? are you going to be a pioneer or circle jerk on this site for the rest of your life? you decide.

    i'm calling every one of you guys out. plus, we have to show these j-spec scorts how the CVH gets down. i dont think anyone has thoroughly done it yet, atleast not in the states. i'm talking going all out with the tranny too (not the mazda clunk box either! ford mtx75 tranny swap! )

    you know the first post on this thread says that "so you don't have to read through 14 pages of text" well guess what page we're on :roll: . And I agree with you wy should the guys crossed the pond have all the fun??? Time to flex a lil muscle and and show them what our spec cars can do. And ounce I get a lil more money around ITS ON!!! as far as I'm concerned. I think the escort is in need of some well over due respect on the streets. I was thinking if somebody shows that our escorts are more than just something that you HAD(no choice) to get to something you GOTTA(choice) to get, well you'd prolly see a lot more escorts around and maybe the aftermarket would wake up. Why dose everyone(besides us) hate our cars anyways??

    Wow this was an amazingly long drawn out discussion. I wished I would have read the first post all the way through. Thank God I skipped to this page after reading 4 of them.
