615cid Big Block Chevy
so looking at having a sheetmetal intake made to fit my needs..($2500)
need a short duel top tunnel ram to fit under a 6" cowl hood..
from top of intake gasket to TB base 8" tall.. so the runners from bottom of box would only be 3" to 4" tall..looking something like this..

OR?
I take a tunnel ram thay made years ago..that I can take the top off of..and replace it with a 1/2 thick aluminum sheet.made to bolt on to the cast base..and have the sheet aluminum top made with the duel 4150 bases to install the TB's on..it would be under $1200 to do that's with the cost of the cast ram..the ram shown below is a 3 piece unit...just unbolt and remove the 2 top pieces.and have a billet aluminum sheet top made to what I want....then have it polished...easy easy...

this shot shows the ram with the 1" spacer removed..you can see how short it would be..sweet!..and if I have to I can have it milled down even lower... make it fit!

I can see that this car is going to be a beast. Seems like you've spared little into creating a great assembly of parts.
So that said, shouldn't the intake be selected based on it's being complimentary to rest of the engine combination? Seems to me that getting an intake "to fit" is a compromise. I understand your desire to have it under the 6" cowl but this seems like a poor approach to an otherwise spectacular build. Unless of course you have evidence that demonstrates how the intakes you propose won't limit the performance potential. And yes, at 600+ cubic inches, what does it matter that you might chop off 20% in output? But that could amount to 150 HP or more.
And further to that, at this stage of the game ..."save a few bucks"? Really? Why start now? Just go for it.

The HP and TQ output rating(925HP/800fpt) is based on a single plane w/a single 1050 carb. as a eng package.(that drops right in).. have talked to the builders about this intake (short ram)set up..they have used setups close to this before.. and have seen better output in mid range. with better top end.. about 30 to 40hp..and on top of that. the EFI of Fitechs. they are excited to see what the outcome is going to be..if anything we are adding power..not taking anything away...in there words.. "could brake 1000hp" but for sure 950hp.."
even if its only 25hp more its a win....and that's just on the eng...before 250 hit of NOS..

but in a nutshell...anybody can bolt in a BBC with a bigass carb...I want to bring in the Crazy power with EFI.and a intake set up.you Do not see every day...just me...
the nice thing is. this will be set up on a dyno and tuned..then boxed up and sent to me.. for install..with all the timing info..for me..so I have a base..before I go bolting on NOS. and messing with the timing...plugs...and logging..with the base. I always have..the info to start from..before I go making changes..and in my neck of the woods. I have 6 chassis dynos..to get info after install...

But in the end. if it works..ill spend the $2500 and have a intake made...and if its not up to snuff (more then)30 hp over a single plane..then I will have saved $1500..and gave it a shot...

the thing I wanted was 100% reliability and easy upkeep..for street driving...for them fri/sat nights..when ya bump into that mustang/hellcat..or hotrod... EFI and 3rd gen Camaros...its whats for street fun...

and after all.. who doesn't think this is just sweet looking. for a street car...

so...its nothing new...lol 7" tall from the top of the intake gaskets..to what we would call carb base...

skinny z

Sounds like win-win. Performance and saving money.
And that is beautiful. (Don't forget air filters!)

with this intake..with throttle bodys on it I will still have 2 to 3 " of room for a air cleaner set up..

after a good show polish..it will be......Necessity Is The Mother Of Invention..

the runners on the short ram are a straight shoot into the head ports... they don't run across the bottom of the intake like sy1 intake..
the ram runs better mid and top end...
that and its set up for almost 3 times the CID ....lol

Smokey yunick sy1

better shot

iTrader: (25)

Thats not an sy1 its an offenhauser crossram. Edelbrock had an str10? I think it was. The same apart from the shape between the 2 banks.

The sy1 has shorter runners and a divided plenum. It will feed most anything you throw at it.

I.now realize this is for a bbc. Sy1 is sbc. So no help ghere sorry.

It dynos with a 4bbl intake. I would have to consider that intake with injector bosses p, rails, and TB added.

damn! this build is so impressive. I give you a lot of credit for all this work and expensive parts. am very very jealous

skinny z

Isn't there a measurable performance difference between a throttle body style intake with injectors in the throttle body (as shown in artic's pics above with 4 injectors per TB) as compared to an "dry intake" with injectors in the runners? The former taking advantage of the heat of vapourization to create a cooler and denser charge?
Not suggesting one is necessarily better than the other. Just asking the question for the sake of conversation and information.

articwhiteZ

iTrader: (56)

placing injectors on/in the runners could bring in a bit more power.(one would think)with/without batch fire..but then it/I would not be using the FiTech system.. I wanted.. this set up is for a 925/1000hp base eng..and easy set up tune and care.. if I wanted more power..like we all do after starting off...then the 1500hp BBC would be in the works..lol this is a street car..with power windows..thats my story and I'm sticking to it..

ya see the eng price is $24.000 (all aluminum 615 925hp single 1050 carb)belt drive/shaft rockers/and other goodys
march pullys $600
elct water pump $200
the intak I'm using total cost under $1000
Fiteck $1995
headers $2000

the above list is what the bbc cost to do what I want..with the car tipping the scales the same as the small block..
then ya have the added cost for things to keep it running at the track with out getting the boot..and keeping it safe..

tryn to do this on the cheap...it not easy... But I have looked at the other post with a guy doing a ram set up close to the same thing with injectors in the runners...I looked for the same weiand intake he used..with out luck..so in the end this is what the plan panned out to be...

Wet flow isn't going to lose much at rpm where flow takes good care of vaporization. But he's building an ahhh street car, where gains from port injection are subtle but useful at the lower end. As for an injector at the port / valve at a proper angle atomizing fuel, it is better over useful rpm overall than any wet flow, assuming apples to apples.

more street car parts...sending in the weld wheels. to have beadlocks added. $400 a wheel..

Curious how this all works out. I personally have not seen any real high performance tbi type builds. Most are port injected and for good reason, as explained above the low speed operation and driveability is a main difference. With todays port efi computers setup is easy and tuning is easy. But i admit the dual tb look is pretty cool

Shaferoff Racing who is doing the engine is going to install this on the engine and put it on the dyno. this engine package with a single Dominator carburetor makes over 925 horsepower and over 800 foot pounds of torque... they will keep me updated... has I want at least the same numbers if they can obtain it...and.. if not...then we'll do something else... and all of this under 7000 RPM... I do not believe this package will be under there guaranteed horsepower rating..

linkage for the above fitech units...is this setup..new in box $127.00

Note:: summit does not stock this Vendor...mods will be made to get it to work on a shorter ram....

articwhiteZ

iTrader: (56)

cant mount them side ways...oops. have to mount them inline..
11" tall from top of TB's to bottom of intake... will be a total of 11 1/2" tall with NOS Plates..so lots of room under the 6" cowl hood..

articwhiteZ

iTrader: (56)

Linkage..called the Guys Who make the linkage..gave them the specs..8 1/2"from Larg hole to Larg hole and with in 1hr they had it made and in the mail.. $32.(I wanted a nice looking set up.nothing off the shelf.simple!). adding a better 1/2" NPT fitting or 2 to the intake. for water and AN fittings.. polishing will run about $400...after its all test fit together...will look right at home on top of the 615 cid eng..

I wonder what the cost would be to polish a eng block ??? just thinking....lol.. then a clear power coat..would hate to polish it when in the car...after all its just a street car...wanted to get the TB's polished..but don't want to mess with the warranty from Fitech..


this with a bit shorter intake. and no crank trigger.will fit right in...

articwhiteZ

iTrader: (56)

linkage came in today..3days from the time I gave them my info...sweet!
that hooks the 2 TB's together.. right now the intake is getting a new 1/2 NPT Bung added and redrilled to mount the TB's inline.

there are linkage set out there..but I want a one off. for this set up. and wanted it clean looking..
my set up should bolt into this..thats the plan..


so Lokar Now makes a bracket just for the Fitech TB's and has a part that will bolt right into the linkage I had made above..

articwhiteZ

iTrader: (56)

mock up time..added 2 new 1/2 NPT Bungs to the front and added the air cleaner tossed on the TB link.. lokar was sending me the new throttle cable braket for the fitech's



better shot


making a aluminum plate the bolts to the bottom of the air cleaner base..that will seal to the hood when closed.for cowl intake.
the NOS plates are going to add another 1/2" the this mess..

new bungs installed

articwhiteZ

iTrader: (56)

lokar braket for Fitech



got this from Lokar. as summit don't have it yet..so I paid ..full retail. and shipping..dont think its a $114 part..and I don't think its going to get a full pull...but we will see..

articwhiteZ

iTrader: (56)

Lokars set up works with my linkage..at rest..

wide open..clean looking set up... want a better clamp then just the 1 set screw..will work on that but for now it works..

articwhiteZ

And now for a bit of color..on the passenger side.. going to add a 2x5in blowout plate to the top of the intake..
(working on getting one anyway)

nexed working on the NOS lines hard and soft..fuel log..and lines to solenoids...running to 1 fuel reg..from reg to TBs and fuel solenoids. with 1 return from reg to tank..
Did get to use 1 part from the old eng/nos set up. my moroso fuel log.. 26 years old. but still new looking..

iTrader: (56)

no on the moroso fuel log...lol...

making gaskets...just in case I need a few.. easy easy.. put on some vinyl gloves..just cover with ultra Blue barely. just to turn it blue..let just tack up..then bolt inplace..now if you had to..you could remove the gasket and use a 2nd time...(not going to) but ya never know..I made more then one..

hope it don't choke the 615cid ZL1+..(My Version) 10.0 EFI Z28

articwhiteZ

iTrader: (56)

some of the ports had to be opened up 1/2 in..

articwhiteZ

iTrader: (56)

rough cut..but its better.. port was dropped a tad over 1/2inch to match the brodix 380 heads

this s the rough cut. then finnish with 240grit for a nice look..

articwhiteZ

iTrader: (56)

did buy the holley sheet metel intake (made in china)..marked sniper.. but the ports are to small for anything over 454cid in my book

articwhiteZ

iTrader: (56)

you cant open them to the brodix 380 heads...but maybe smaller heads would work.. note port size..welds just outside of sheet metal

articwhiteZ

iTrader: (56)

from top of air cleaner to bottom sitting. 14 1/2 inch (before polishing and porting) test fit with linkage.NOTE added better water bungs.AND more of them.
will have to see after getting the eng in and hood on..if I can go with a taller air filter..wouldlike a 3" tall filter. this one is just at 1 and 3/4 inch tall

skinny z

You definitely need more air filter.

articwhiteZ

iTrader: (56)

if I have to I can drop the base 3/4"inch and add another 1 1/2 to the top giving me a full 3" tall air filter..as you can see I can drop the base down...by removing the necks seen in this pic. will have to make the new lower necks...no biggy.. say hello to billet base! then stack 2 filters on top of each other..until I get one made...that's if I need to..

Say hello to Fat Elvis..

I gotta say, those are some mighty fine numbers you've got there, my man! Congrats! Cant wait to see pics of it in the car all buttoned up!

I know I have always liked the prostock intake look.. and wanted it under my hood..for the same price I did this eng.. they do a 8-71 on a bigblock..but I make more Hp this way and its under my hood..
