    cam off 1 tooth?

    Sorry to read this a little too late, but a simple cranking compression test would have prevented that timing cover tear down. Which you should check anyway. LUK

    Should I trade carbs??

    More proof it really isn't a "too big of a carb" situation/problem. There are some basic calibration/tuning chores you need to do in order to fix it...... chores that are needed regardless of the carburetor size used. Is the vacuum advance canister working? What is the initial spark advance...

    Should I trade carbs??

    I guess the classic diagnostic/ID cause/correct/tune/calibrate problem solving procedure is one that should be avoided like the plague then.... :nonono:.... BTW, is the symptom really carburetor related? What about the spark advance curve? When does full spark advance occur? Is a distributor...

    Should I trade carbs??

    The symptom you are having with that carburetor is not due to its size. And no, a 750 CFM is not too large for a 302 CI engine, nor is it for a 79/159/238 CI (choose your way to determine CID) wankel. Nor is a 1000HP Holley based professionally designed custom carburetor too large for a...

    75 MM Throttle Body for my setup?

    Why is there a tendency to try to relate components selection to engine power production prior to their selection? Aren't the components (including the TB) supposed to be "contributors" to the engine power production among other things? If a 75mm TB for a pushrod 302 is "too big" ........ why...

    Setting idle

    EEC programmed idle set point target is 672 RPM, maximum ISC controlled idle set point is 850 RPM.... and yes, the EEC does set/regulate idle, it is one of its duties.

    setting a TPS

    OMG.... so now you have TPS setups for N/A and Supercharged setups? :rlaugh:

    setting a TPS

    If you don't have a TPS related KOEO failure code, the TPS doesn't need to be "fixed"..... it's within the EEC "pass" range.

    setting a TPS

    You don't adjust a nonadjustable sensor by design. The mythical setting at .999 vdc is that.... a myth. The EEC automatically sets its working range and minimum value as long as its closed throttle position is between .5 and 1.19 vdc (.7 - 1.1 vdc provides for any temperature/voltage variances...

    Degreeing A Cam

    If you really want to ensure installation accuracy, yes...... you need to degree it. Otherwise, you may end up with a cam installed anywhere in a ±4° window (advance or retarded).

    5.0 cam selection help

    1.72 ratio roller rockers, upgrade valve springs, degree that cam and install it 2°-4° advanced is a better "upgrade" path based on your setup.

    trick flow stage 2

    Check the graph posted above, if you have a .600" lift cam with the intake valve open event @.050" tappet lift happening at 5° BTDC (.080" valve lift with 1.6 rocker and .086" valve lift with 1.72 rocker) will have the same lift with a .300" lift cam that opens the valve @.050" tappet lift at 5°...

    trick flow stage 2

    There is no formula. You need to measure the "partial" valve lift of both valves during the 20° BTDC - 20° ATDC exhaust-to-intake cycle changeover phase, and the gap between them and the piston within that window. The following graph shows the difference between 1.6 and 1.72 rockers and the...

    trick flow stage 2

    Total valve lift has nothing to do with possible PtV clearance issues. Stage2 cam uses an X-303 intake lobe so clearance on the intake side shouldn't be a problem even with stock heads based on what I have experienced. Exhaust clearance needs to be checked. Checking for PtV and correcting if...

    Very confused with timing gears?

    You need to degree the camshaft to ID "where" it is installed in terms of valve events. The "dot-to-dot" or "straight-up" installation (as it is wrongly called)..... could mean the E-303 is off by 4° either way (advanced or retarded). This is true for any OTS camshaft BTW.... BTSTDT many times...

    KOER codes 44 & 94, just one quick question about them...

    Nope..... codes 44 and 94 are KOER exclusive codes. IOW.... they are logged as part of the self test routine, they never get stored in memory.

    can anyone lookup a ford part #?

    Same way an E7 casting number = 1987..... the part number starting with F2 = 1992 or the release year to manufacturing. A 1990 Mustang harness would start with E9ZB- or F0ZB-

    checked my IAB voltage and only got 11.93

    Keep in mind that with the IGN ON engine OFF, the ECM cycles the IAC to a pre-startup open position.... which will show as a voltage drop when compared to battery voltage.

    little confused on using a jumper to check engine codes...

    That would be code 21 or ECT sensor out of range.... IOW, too cold. You need to first make sure the engine coolant temp is above 160° and then run the KOER self test. LUK

    AFR 165's, TFS Stg 1 cam, pushrod length?

    I worked two similar customers setups..... one required 6.300" and the other 6.350". What will yours need?..... :shrug: You will never know until you...... check what your specific setup needs.
