ok so there is a problem with it idling fine i'll fix it when i go back to work i not knowing a lot about racing and just getting into it figured that was normal. For your info, i work as a diagnostic technician with an ASE in brakes, heating/AC, engine performance and engine repair. Been doing this for 3 years. look if you want to debate fine dont be an @$$hole about it. the MP1 non egr intake manifold is 650 cfm, if im wrong then correct me. I used the 68 mm tb for more airflow, no it didnt bolt right up but thats what you fabricate for. Ive looked for pistons with lower reliefs but couldnt find them in my mopar nor my summit racing parts catalouges. if you know then give me a part number.
the final cc was neither. 58 cc per port. no i shaved the valve cover.... what do you think? As far as money goes, im 22 not married with no kids and live 1 step above the ghetto(thats my choice since im cheap when it comes to living space). ive got money to burn. you want pictures sure, ill post them up for you after theyre developed. dont think this was all done instantaneously this was 2 years of saving and 9 months of buying.
while youre at it go replace that muffler bearing, and refill the turn signal fluid.

"no i shaved the valve cover""

holy crap! you get dumber with every post


how would shaving the valve cover allow for the intake manifold to fit flush on a set of freshly shaved heads mounted to an engine block??


seriously, i'm thrilled that you have read a lot and seem to be figuring some of this stuff out.. i mean, i did throw in the trick question about the cc of the heads for you. BUT please educate yourself more before you start posting nonsense like this!!


also, do you have any pix of this custom fabricated plate that allows for the 68 mm throttle body to fit on a M1 manifold? Do you have a 6" hole cut in the hood for clearance?

HOLY FRICKEN CRAP! ITS CALLED SARCASM dude. the line was actually "no i shaved the valve cover..... what do u think?" and your absolutely right it has nothing to do with clearence. Ill be happy to post pics. I have a camera but its the old fashioned type, but i do have a scanner. id love nothing better than to show off what 9 months of intesive labor has produced. just dont make fun of the paint, its still primer grey. Its like the japanese say, when you create something you put a part of your soul into it. Im educated enough about how stock engines run and have been learning about racing over the past year. the tb plate i fabbed didnt have clearence problems. Then again i have a functional cowl induction hood. Ill admit that i probably havent been doing this as long as you have but i have a good concept of how an engine works and what each part does to an extent. i still could use a lot of tips especially on getting the idle down, since apperntly i was wrong in assuming 1200 is normal. i dont really spend a lot of time on this forum so a lot of what ive learned is what others say and tell me. the 68mm tb was my shop foremans idea. hell this is the longest time today ive everspent. but considering its my day off it all works out. I appreciate the sentiment about me learning cuz yeah im still learning. I did go to a trades school to learn this field that i have a passion for.Simply put ask me about stock and i can help you all day long, ask me about aftermarket i know a few things but not really a lot.

so if you dont need heavier springs when putting a v8 in a dakota then why does mopar make v-8 and v-6 torsion bars? for fun?
if going from a v6 to a v8 you will need them, goiing from a 318 to a bb im buessing no
put in a cummins and your doubling the 440 weight :)

anyway i would put stiffer springs in, considering he has a 88 it will only have a v6 not a v8

What?????? A 68mm TB flows less than a 2x50mm stock TB and it flows far less than an easily modified 2x50mm. That must have been an awful lot of work for nothing. I think your shop forman is an idiot.

Super-bee,
if you take the time to look under a dakota, you will see there are no torsion bars nor anywhere to mount them for 2wd models because they all(all meaning gen 1 and gen 2 dakotas) use the same springs. about a one inch think spring. torsion bars are used on 4wd dakotas (hint hint...thats why mopar makes them). so i reitterate, stock springs are sufficient. or if you want a 4wd 440 dakota, then you will go with torsion bars. you cant have both unless you plan wasting your time weling on a set of torsion bars.

well if you got pix, post them and i'll apologize for being an a$$hole.. if you dont have pix, i'm just gonna leave it be.


the engine's idle doesnt have anything to do with a lot of the modifications you have "done". The computer controls the idle via the idle air control valve. Your computer would let you know really fast that something isnt right when it figures it's idling at 1200 rpms. Now if that's 1200 rpms bouncing, you probably have a vacuum leak.

If you did all this, that's a lot of neat custom work but i dont think it's gonna perform as great as you think. A 6 speed would be a blast, but that wont do that much when you motor is lagging behind. Your camshaft is probably somehting around a 206 #@ .050 duration cam and is better than stock, but still very very mild. You said you have R/T heads which are 60cc combustion chambers. You stated they are now 58cc after you had the heads shaved. That's probably .005 - .010 to kill 2 cc's. That wouldnt effect you much on the cam choice as the pistons arent exactly at zero deck. You should be able to go with a much stronger camshaft for your application.

nothing wrong with primer gray at all, my truck is about to be all primer before it gets a coat of plum crazy.. it all takes time and money which is two things i have little of.. so it's gonna have to be a process. Get some pix up, i'd really like to see the stuff you fabricated for the throttle body.


as for the springs, V6 springs will work w/a big block but probably not be very fun for everyday comfort. here's a couple things to know.. a 400 BB weighs about 60 lbs more than a 360. A 383 weighs about 70-75 lbs more than a 360 and a 440 weighs about 140 lbs more than a 360. With just an aluminum water pump housing and aluminum intake manifold, a 400 bb weighs the same as a 360.

Also, I've said this in one of these posts....the Shelby Dakotas, 1989, started as V6 Sport models. The 318 was transplanted, but there was no change in the suspension. No heavier springs were used.

well if thats true N56629l, then ill probably get a 2x50. if you got figures first that will really help me get a better picture. My shopforemans a ford guy anyway so yeah ill agree that he's an idiot :-). thanks intensedak. if the cam i have is mild. what profile should i get to get the most power out of it, even if i have to replace the pistons(part number would be great) and geting the heads ported. also, ive looked at getting a stroker kit. dont know much about it though. my whole goal with this engine is to be n/a with only a small shot of nitrous. therefore it means a higher compression ratio.

Plum crazy purple on a gen III dak eh? id love to see it. I think that would look fricken sweet! You doing chrome or stainless steel rims to match? Im looking at painting my dak Night Tides(du pont makes it, looks like the night sky in daylight and a blackhole in moon/starlight). Running 15x7 chromed bullet hole rims with 235 60's all around.... want bigger tires in back though(better traction taller final drive ratio).

satakieli, the 68mm is a single barrel designed to fit the 4.7. It doesn't fit the Magnum manifold. I'm not saying it absolutely can't be done, but what would be the point?

How much more or less do they flow? I'm not exactly sure on the 68mm but just do the math. The amount of flow is fairly close to being proportional to cross-sectional area of the venturis. The 68mm is 3631 sq.mm and the 2x50 is 3927 sq. mm.

Sorry, but much of what you claimed to have done makes very little sense to most of us.

i see your point. basicaly i wasted time and money making it work since it doesnt flow near as well. i guess ill go get the 2x50 and put the 68 on ebay or something. while im at it ill throw a wrench at my shop foreman for telling me to do that. in the end it really just flows less and was just useless. so in your opinion who makes the best? and is that the best size for maximum airflow?

Yes, I'm swapping a 383MopowerMagnum in my 91, I
figured on having to build my headers from a set
of flanges,&etc. but if there's any out there
aftermarket built already? I have yet to find any
such? Any leads or places that have such would be
appreciated.thanks
