    Right now i have 75 mav with i6 250. Im getting my parts and plans together to drop in a mild 302.

    Now i weighed my car and it sits as is 3,100 lbs. After i lighten the car i hoping to reach 2700-2900 lbs. My mild 302 is projected to make 350-425 hp. Now with that said...

    would it be a good idea to box in the frame??? and how did the grabbers pull that kind of horsepower with ot twisting frame?? I havent heard of grabber owner twisting frame so i wanna know what did they do to it or is that just factory strengthening??

    The Grabber package was just for looks - there was no "hot rod" engines in them. Those who put big HP engines in unibody cars usually start with sub-frame connectors. If they are making enough HP to go 10s (10.99 and lower) use roll cages.
    The cars are the same as all the rest - just paint and decals.

    These cars are unibody and are technically, already boxed in.

    i'd feel pretty confident with runnling 300 hp in a stock maverick body. unless youve got some big meats in the back and enough hp to to yank tires off the ground. i'd start with subframe connectors though

    the most powerful engine you could get in any maverick, including the grabber was a 2bbl 302 making about 200hp. all "Grabber" ment was that your car had some stripes and scoops, it didnt mean it went any faster

    ok cool so in the 7 yrs of the mav nothing was ever done differently with the frame.

    yes i plan on running some meats on the back of my mav. go big or go home is what i always say.

    so say this girly girl does hit mid 10's in this thing, my frame isnt gonna twist? but for added comfort get sub frame connectors??

    Yes to the subframe connectors. If you run mid 10's you will need a roll bar.

    Just out of curiosity was you in the car or out of the car when you weighed it? I know my 70 weighed 3050 with me in it. That equates to 2850 give or take a pound:cry:

    I am hoping to get my car down to 2700 lbs

    Also isn't it great to be able to say MILD 350-425HP.....:D
    That used to be WIld evn just 10-15 years ago
    its becoming the norm:thumbs2:

    lol well to me 350-425 hp is mild lol my idea of v8 with weiland supercharger is radical.

    FYI i was out of the car and it weighed 3100. but then again i do have the bench seats and the big chrome bumpers. I plan on getting rid of the bench seats, switch to the small bumpers, fiberglass fenders, hood, and trunk. I might do the doors.

    I wanna shave as much weight as i can because I kno with the v8, and the suspension upgrades its going to be adding mroe weight back on.

    mid 10's is pretty serious. your definatly going to want to beef some things up then

    my definition of mild is like mid 13's lol

    and yea, all 7 years or the maverick are pretty much exactly the same

    If your talking that kind of power, and with the "big tires"

    Your going to need subframe connectors at the minimum. And if you plan on going that fast at any real track, your gonna need a roll bar or you wont be running it at all

    lol you guys must have some strict rules on your tracks back there. Here I can run up to 10 flat just about and not need a roll cage. If you hit 9's or go fast enough to where you are boarding 9's you need a roll cage.

    I have seen tons of cars and trucks run 10's and the track guys let them with out a roll cage.

    But seeing how i know you guys care Ill see about getting one set up. :thumbs2:

    NHRA rules require the roll cage at times faster than 11.0 seconds....
    If your track isn't enforcing the rules then watch out - they may be skimping on safety else-where too.
    When are you required to use a driveline loop, safety blanket or scatter-shield, helmet and on-board fire supressor?

    That I could not answer but you know what I think because when I see the cars that are hitting 10's its on test n tune night. They are more lax that night because it was mainly for street cars to race.

    So i guess that will explain it, on test n tune nights you dont need a roll cage or an extinguisher becase I guess they are not expecting street cars to any faster then 12's but I have seen 2 daily drivers hit 10.3 and one hit the MPH for 9's but since it couldnt hook for crap it was 10.02.
