    That '72 4dr is probably heavier(or will be) than 2600lbs.My '75 4dr weighed 3170 W/O driver,/302,c4,8" rear.No P/S or A/C.I wouldn't think crash bumpers would add over 500 lbs,plus you're going to a 9"(slightly heavier than the 8") and an iron headed W is about 100lbs more than a 302.I like your idea,my '75 was a blast to drive/race.The 4dr really hurt some egos:biglaugh:,have fun

    Only waiting on $$$.
    I think Mavericks got about 200lbs heavier every year they were made.

    But you are probably right. Once I add all of that weight.

    I'm currently rebuilding the 302 in my two door.
    I bought it to use for parts then my wife decided she liked it, and it is in really good shape. So the 408 is back burnered for a year or so.
    I'm going to wait and do it right.

    I may be forced to sell my 4dr here soon if I have to move.

    408 cleavor

    I think the best low budget answer to running a 408 on the street in a car that will see plenty of track time is a 408 CLEAVOR! In a car under 3000 lbs. you won't have to spin the motor very high to make it flat move. So, you could go with a cast crank, good I beam rods and "hyper" pistons for the short block and run a set of 4v cleavland heads that flow plenty good stock. Now that would leave a good chunk of change left over for a roller cam.
    As far as the rear suspension goes...I run factory leaf springs with slapper bars and 9 inch wide slicks on my Mav and the car turns in 1.39 to 1.40 second 60 foot times every run....So the stock rear suspension can work fine with some tuning.
    How quick/fast are you looking to run the car? The low buck Cleavor combo should put you in the mid 11's with no problem.

    11s would be plenty good. Thanks for the input/ideas. I will research em. That build does sound tempting.
    I'm also thinking about a 393 because this 302 I have opened up has some sweet dished pistons in it. I want low compression.

    Stock dished pistons

    Ahh yes, but those stocker dish pistons won't have the correct pin location for a stroker combo....

    ive really been kicking around ideas a lot and i think im not gonna boost my comet... that GT42 will have to wait for something else... instead im leaning towards a 400 block instead... Im sure a 351m block could be had for next to nothing since most people just assume they're worthless. Full high compression 400 build-up and some of those beautifull cleveland heads/intakes, I bet i could push 400hp/tq with minimal extra cost. shave the hell outta the font end, coil overs front and back with a 4 link on a 9" rear... either a c6 or 4 speed and ill have an odd ball monster i think.
    I dont know tho, its a heavy block, tranny, and rear. and i was kinda aiming for lightweight... i would always shove a turbo 2.3 in it, but that weighs as much as a 302.

    btw, my 76 weighed in @ 3100 lbs pin on glass hood, AC removed, and a full tank, no driver. just for reference (this is on farm scales by the silos, accurate within 20 lbs

    Sorry dude, but the 393 uses stock rods and 302 pistons.
    He's got the perfect parts.

    Also, the 9.2" tall Cleveland is a tight fit in Mavericks, as is the 9.5" Windsor with stock heads.
    The 9.5" block with Cleveland heads would be horrible to manage in a Maverick. Not to mention the cost in Clevor parts and no hope of getting headers other than making them.
    Then there is the fact that stock 4v heads don't flow as well as some of the top aftermarket aluminum W heads these days. Then there is weight, which is effective HP loss/gain.

    I am a big fan or Windsors, Clevelands, and Clevors... I just realize each has it's place.
    Many will disagree with me, but the Maverick is a place for a Cleveland IMO. The shorter deck height and exit angle of the exhaust ports are very accomodating to our engine bay. That's what I have found anyway...

    351m and 400 use the same block.
    Pistons and crank are the only difference.


    For the same weight, or same money, you can get far more from a 460.

    Gotta redo the entire front end to get a Modified or 460 in.
    There is not enough shaving to do it safely.

    Engine: Heavy
    Tranny: Heavy and high parasitic losses. However a C4 can be used with a big block. There is a bellhousing called "super bell".
    9" rear: Not so heavy for the extra strength you get. 8" is weak and only about 10-15 lbs less 28 spline vs 28 spline.

    yeah i know this, the reason i specified 351m is because it seems to be common belief that it is a junk engine and is worthless. where as 400 owners enjoy them more and dont find them so worthless... ultimately its a mind trick and i know im getting the same thing

    yeah, i reason that to myself a lot, im still going back and forth, i need to see some 460 installations... the size requirements of the headers scare me. (but im used to my buddy's 545 with 2 1/8" headers)

    will it fit within the subframe rails? I can design a whole new suspension ... i suppose its closer to a MII conversion than shaving at that point, you're right.

    how bout top loaders?
