    I posted some pics in the 'general' forum from when I had my
    Engine/Tranny install day on Saturday.

    My clever plan (plagiarizing Ivy) was to have the engine and
    tranny be easily removed as a unit by modifying the top radiator
    support to be removable. Great idea - I'm not abandoning that.

    My delima now is this: I had a problem with the after-market oil
    pan hitting the drag link on the steering linkage.

    Not being the brightest star in the universe, I measured how
    much clearance I needed to allow the 7-quart, rear sump oil pan
    to fit nicely. Had the pan modded to those measurements.

    I didn't want to make the reservoir area too small for the oil
    pick-up, so I cut the clearance pretty close (note: the bottom of
    the oil pan's rear sump reservoir is lower than the elevation of
    the drag link).

    Fast forward to installation day: The engine goes in - tight fit at
    the oil pan and drag link, but it fit. Then 'it' happened. Someone
    told me it wasn't going to fit "because (and then he proceeded to
    show me) the 'drag link' moves backward as the wheels are
    turned" - causing interference with the oil pan. :eek: Boy did I
    make my girlfriend look stupid then! (of course I blamed it on
    her - jeez! that's another reason I have one around).

    Anyway, I'm hell-bent on keeping the rear sump oil pick-up as this
    is a strip car only. When the car is under acceleration, I want all
    the oil volume I can get to surround the oil pick-up.


    Options:

    1) Revert back to front sump design, put a standard Maverick oil
    pan on it, hope the reservoir doesn't run dry when the car is
    going down the track (under acceleration) and put her on the
    track in a few weeks.

    2) Modify the aftermarket pan to allow enough clearance
    between the pan and drag link - all at the cost of reducing the oil
    capacity and needed volume surrounding the pick-up (not really
    what I want to do - engines without proper oiling = money).

    3) Toss the stock motor mounts, fab new ones to not only move
    the engine closer to the fire-wall and away from steering linkage
    but also lower it at the same time. This will provide me; a) the
    ability to run the rear-sump oil pick-up; b) better weight
    distribution for traction purposes; c) better handling at the top
    end of the track.

    I'm going to attempt number 3 first. I'll resort to the front sump
    as a last resort.

    I'm expecting the car to run in the mid 6's (1/8th mile). I know a
    couple of you guys are racing the 302's, and 347's.

    To the guys running close to these numbers, what oiling system are you running? Any problems with oiling/other?


    Thanks for your input, guys.

    of note:
    347 - N20 enough to go to 600 h.p.
    small hyd cam - shift point ~ 5,800
    plan on ~1.4XX 60 foot, 6.5 (hopefully lower) 1/8th.
    engine out of '90 Mustang, EFI
    AFR 185 heads, 58 cc chamber
    7 quart after-market oil pan originally used in Mustang - modified
    to (incorrectly) fit Maverick


    (Whew! I haven't typed that much since I wrote my
    make-believe true-story for the Penthouse Forum!)

    I"m running an 8 quart front sump from Pro Mustang.....no problems sucking it dry, even with the tires up in the air and a high volume oil pump!! I"ll get you a picture!! This pan has a built in baffle that keeps the oil where it needs to be!! [​IMG]

    I would do that...

    ...buy a deep front sump oil pan with built-in baffles.
    You start moving the motor back and down and you
    are going to run into possible header clearance issues,
    as well as driveshaft length(probably not a huge issue),
    and angle differences re: pinion etc.

    I'm running about where you want to, but with a 351w, if that makes any difference. The pans are basically the same...except the rear of the windsor pan is wider to accomodate the larger 3" mains. They both hold 4 qts, plus filter total of 5. Have not had any problems at all with a stock pan, and that is with .003" main clearance/.003 rods, and a HV pump. Spins about 6800 max, 60's are usually in the high 1.4's weather/track permitting. I do have a windage tray installed as well as a home-made pan baffle, but last year with the 393, I had neither one and still had no problems with oil starvation.

    I run a front sump in mine. I am having "zero" oil starving problems at the launch. The one "problem" I know of guys having that run rear sump, is when they get to the "big end" of the track and they let off the gas, the car noses over and all the oil runs away from the pick-up. I know that this can be compensated by kicking it in neutral and killing the motor.
    Good luck.

    Well, with your inputs, I do believe I've changed my mind and will go to the front sump set-up.


    Steve, I like the idea of having an 8 quart pan, but I couldn't find it on www.coasthigh.com. Do you have a P/N please?


    Thanks guys,



    Rick

    I have a Moroso 8qt. pan too ...it has good baffles in it and fits the car just fine,and its never been a problem for me but you do lose a little ground clearance with it.
