351w power

well im new here just got a s/n couple weeks ago, havent posted anything yet so here we go , im kinda new to mavericks i bought a 75 mav for $150 2 years ago , only 51000 miles drove it for about a year and began the drag racing project, it started life as a 250 6cyl c4 , a/c, power steering, LDO , now i have a 351w almost ready to run i was just wondering how it would run drag racing, stock 92 bottom end , w/ c9 heads w/ new valves , spings, etc, they got milled about .10 they are gasket matched ported, cleaned up the combustion chamber 1.6 steel roller rockers, comp cams magnum , 518/518 292/292 duration , eldebrock rpm air gap , w/ holloy 750 DP probley over kill , 3000 stall converter , only thing havent changed is rear end is still 2.79 getting ready to buy 4.11s and mini spool , oh yeah and slicks , i know there is alot of possiable combos out there but maybe someone can tell me what you all think thanks
oh yeah i also converted to small bumpers alot less weight just thought id add that

 

are you running an 8" rear or 9". mini spools usually say not to use drag racing and i know the nhra rule book says that if you are locking the rear you must use aftermarket axles. i did run a mini spool in my 64 fairlane, 302, but i only ran high 15's. my maverick with a fairly stock motor, comp cams .512 lift, d0 heads. 4.33 gears ran 12.80's with good air at 1200' density altitude.btw, welcome to the board.

 

yeah i have an 8 inch right now i want to go to 9 inch , i have herd many things about mini spool even on here some say they will be ok so i dont know, yeah i know if you have a locked diff you have to have aftermarket axles but if you dont tell they wont know, yeah i want to be in the 12s so i should be good we will see thanks

 

might need the gears to get into the 12s. but should be high 12s area.

 

i think 411 gears will be to much you will be out of engine before the end of the 1/4 . ..what kind of rpms you going to try and turn ?? dont think your combo will make it to 6000 rpm . ...could be wrong .....i think you will be shifting around 5400 rpm

 

should rev close to 6000. what is .050 duration on the cam? what size tires? i ran a 67 mustang (about 200 lbs lighter than you) with a larger cam, worse intake, 4.30 gears 28" slick, C6 trans, 3000 stall. shifted 6000, thru traps at 5600 at 106 mph. 12.70s area depending on weather.

 

was that a 351w ??

 

i was running 12.80's with mine, running 4.33 gears and m/t et streets. 26x10.5x15. i can't remember wether i shifted at 5400, but i know that the shift light came on again just as i got to the finish line.

 

How about pictures?

Have you installed the engine? Did you cut the shock towers?

 

yes it was a 351w motor. .030 over, flat top cast pistons, offy 360 intake, D0 heads opened up, open headers, roller rockers, 750 dp, cold air hood scoop. took me to the bracket finals 2 yrs running & 1 track championship in heavy.

 

i did notch the shock towers a bit, i used 64-66 mustang hedman headers w/ 351w , havent installed yet mocked up b4 shock tower mods and headers didnt fit right so im hoping that the shock tower mods will help this, sorry no pictures right now, yeah i was guessin at shifting around 5800 maybe little lower, 26 inch slicks, its a 292 duration 244/244 duration at .050 any body have any ideas for rear end gears maverickgrabber said maybe to much gear im not sure, does any body have any ideas for headers in case they dont work ??

 

Ok I got some idea's.

The cam 244 @ 50 is a good place to start. The 26 inch tires will be a tad short but will work well with a 373 or 390 gear. Stall (3000) may be a little to small for all drag but would be ok for both street and drag, keep in mind that you will ALWAYS want to go a little faster.

Now if you already have most of your parts then put everything together and go have FUN! Email me when you are going to Mason-Dixon and I'll try and be there.

Headers... here is a really sore topic! NO ONE makes headers for our cars.
Hooker 6208 is the best BUT I hope you can do some fabing. Windsor's are not made for the Mav/Comets and once you go that route be ready to make things work. If I was doing it all again I would've gone with a 347 stroker and then just sprayed it hard.

I haven't been racing this year "yet" but I'm going this coming weekend if the weather lets me.

Remember, Rome wasn't build in a day.

Shock towers... Now if you are going to put a 351W into a Mav/Comet then you MUST do the mod, without the mod life working on your car is a Bit$h.

I think with what you are doing if you can put in a lower gear then you should see low 13's to high 12's but if you don't then don't get upset, you'll get there.

Good Luck!

As always just my .02

yeah i understand no one makes specific headers for our cars , i just wanted to get some input from everybody , yeah ill be at mason dixon as soon as i get her together probley a month or so , as soon as i get my heads back from the machine shop i can put 95% of the drivetrain back together, just ordered fuel lines and fittings from summit all i need is distribor and contol box , when you only make 9.50 hr it takes time lol
i seen the pics of those hooker 6208s on stephens comet but would that work w/ a 351w in a mav/comet , yeah terry ive seen your maverick at mason dixon , its bad A$$ you have the shelby tail lights right? thats an awesome look oh and on the tires if i run 28inch will that work better w/ a 4.11 or will it be same effect as 26inch w/ like a 3.80??

 

28" & 430 gears work well. if you are buying both, put the biggest tire you can under the car & then get the proper gears for your mph.

 

I ran mini spool in both 8 and 9in rear's for many years with no problem as long as you check things out once and awhile. The cross pin that holds it in the carrier is what usually breaks or wallow's out the hole's. I am thinking that if you are running an NHRA sanctioned track, there is going to be lot's more rules to follow too. When I shortned the 9in housing's for our cars, used the 8in "Mav" axle's, up until the 408 and alky injected engine, went in the Mav with 14 wide tires. I still run them in my car with 331 alky injected on 9in MT's. 1.39 to 1.42 sixty's and 6.80"s i the 1/8th. Will have to get some Moser's one of these day's, those axles are now 8yrs on the track with a few thousand passes on them. If you use your's with slicks, do put in 3in long wheel studs and open lug nut's. Seem's as though the tech guy's glance at them and assume they are aftermarket axles. Rules are made to keep everyone safe, but sometimes common sense should be the thing to follow on a 12 second car. Ford 8 and 9in rear's, will very rarely break an axle outside the retainer, so wheel should stay put, not like "C" clip style's. Does make for a hairy launch though, when one goes. 450 for axle's and bearings, 200 for a full spool, is still cheap for safety and reliability. The more confidence you have in your machine, the better driver you become. Keep us informed on your project and most of all, have fun.
