ok i finally got a 406 now i need to find out how to make my 89 intake work on my dart heads so do i go after market or could the factory one be fixed to work :hail: thanks 4 any info

 

Just go stealth-ram, let it breath.

 

Or super ram....

 

I vote stealthram

 

If hood clearence and smog arent an issue (which i doubt would be because u are building a 406), i would go with a stealth ram.

 

yeah stealth ram is what i was thinkin noticed sticky after posting stealth ram has both patterns[intake].. looks like you have to go with whole kit ..was hopin 4 intake swap now and maybe work from there,butt noticed nothin is compatible with stealth ram ....fuel rails ... thanks 4 all youre imput this site rules :rockon:

 

The million dollar question. What cc are the intake ports of your Dart heads? That will make the decision on what intake you will run. Anything 215cc and bigger will require welding of the HSR or LT1 intake. Only the Miniram has an intake that will direct fit large cc heads.

 

well i just got the engine the guy said there sportsmans and they were 800 a set ..so im thinkin the 200cc ones ....ill have to see thanks 4 any input they are world products i thought they were darts

 

what about the edelbrock i see its a lil cheaper is that cuz it sucks ?

 

Are you also asking how to make the 89 base work with the Dart heads also? If so, you need to elongate those centerholes that are drilled at 72* to find "standard" SBC heads.

But, as others suggest, consider a different intake in the long run. The TPI just flat out runs out of breath too soon, especially on a big mouse like your 406.

 

so the stock 1 can bee drilled out? i am thinkin after market just dont want 2 pay full price.... so lookin 2 see what 1 is most desireable. then find 1 in the classifieds or....my eng has ross flat tops pink rods and for the moment 525 crower hyd cam steel crank .. if that helps any. thanks again:hail:

 

Do you need to pass smog? THAT is the million dollar question.

 

no smog laws here all though with the set up i have in the car all smog is still hooked up.[i know its robbin power just havent taken it out ] no plans on hookin that crap up on 406 though... thanks again 4 reply:rockon:

 

Miniram with the appropriate cam.

 

youre talkin about the tpis 1 ..write........that place isnt 2 far from me ..i looked at them butt at over a grand not very affordable butt what iz ....... thank 4 youre 2 cents

 

If I were to do it all over again, I would modify a single plane intake manifold for EFI. Stock TPI stuff cannot properly support a big inch small block. I ran a SR base with SLP runners and a 58mmTB....it was okay but the motor ran out of breath at 5000rpm.

 

406 I'd say the same (miniram) to you as well, so long as you don't have to pass smog.

green - If it's too rich, search for the LT1 Conversion and call John.

 

I wouldn't put a miniram on a motor unless somebody gave me one. Not that it isn't any good, I just wouldn't waste the money when I could put together an efi single plane unit that would be more effective....and cheaper

 

hey there 406 i was hopin 1 of you 406 guys were gonna pop in . iwas checkin out those intakes also .what about the throttle body's ? are theese the holley units or do you get 1 else were? im tryin to do this with as much stuff i allready have. ive seen a intake 4 $500. vic jr with fuel rails [like u were talkin about] is this goin price? thanks everyone

 

just read about the lt1 set up ... sounded pretty good butt..........i was hopin 4 a lil quicker time than 12s looks like a stealth ram time .:lala:

 

Cheaper? Before or after you buy a throttle body?


Seriously though, I'm about to put a ported TPI on my MegaSquirted 406 and have read all 'it-wont-run-over-5000rpm' stuff.

What are you single plane guys doing for throttle bodies? Keep in mind, this is supposed to be the 'cheaper' route.

You want a nice one from Holley? Thats over $600! I really don't have the machines to make a custom adapter like antheses (sp?) did with his setup and Vortec throttle body. I like the idea, I just don't have the tools or know-how on this one.

It doesn't need to be pretty (although it'd be nice), but it needs to be functional first. Holley and Edelbrock carbs cost around $250-280 new. An EFI throttle body shouldn't cost more.

I didn't say cheaper for you, I said cheaper for me....but then again I'm a pretty resourceful person. I have a bridgeport and a tig welder at my disposal too

 

You want quicker then 12's? How much money you got? It really doesn't matter too much what intake you have, you can go as fast as your wallet can afford.

 

12s aint nuttn i can putt a carb on and do that ... im thinkin down the road ..what reason would i go to all the trouble [wiring in and all] to do the same time i could do on a carb set up ? know what i meen? i really like my tpi butt its lookin like i just mite take it out in favor of the carb. im just tryn not to switch more than i have too

 

As you can tell, everyone has their own opinion on an intake for a 406. My choice is the MiniRam. The combination of a 406 with good cam, heads and a MiniRam is a very stout combination.

Mid to low 11's should not be a problem.
