Intake Manifold

[BigRedChvy383]

Alright, since I'm going to have to go with the TBI for just a bit longer, I'm going to look into getting one of the only two (that I know of, fill me in if anyone else has made TBI intake manifolds) intake manifolds on the market. Is it the Edelbrock intake that already has the holes drilled out for the mounting brackets for all that electronic garbage? I remember reading somewhere back in the day on the board about this but I want to be for sure. And the Holley one I havn't heard much about but which is the better one? Thanks for the help.

I'm not sure which intake is the best, but I have the BBC version of the Edel TBI intake and it is pretty nice. It was an easy install. Everything on the oem fit well on the Edel.

Josh ( Badburban) has the Holley and myself along with 91 Bowtie and maybe some others have the Edelbrock 3704. I personally am happy with the fit and finish, it was an easy swap and everything bolted up as it should. To run a 454's 2" bore TBI however I need to bore mine out, whereas the Holley is already at 2". The downfall of the Holley is brackets need to be fabbed as pretty much nothing bolts up easy. Which one will support more power? Thats purely speculation, some say the Holley and some say the Edelbrock, I like my Edelbrock but have nothing against the Holley either. Now you could just run any old carb manifold too, and just put a TBI adaptor on as that works too, just once again bracketry becomes an issue, but if thats no biggie you can go that way too. Its up to you and what you are willing to do, however since you obviously dislike TBI, why not run the stocker until you can get rid of it, or run a carb manifold with the adapter so you can go to carb( unless you are going to aftermarket EFI) later on.

You should just keep your stock manifold and port it and buy the spacer. I bougth the Edelbrock cam and intake combo and it was the worst 350$ in mods i have ever spent. I cannot imagine the Holley being much better. Hope this helps you .:burn: :cheer:

can anyone tell me how much the edelbrock intake runs. i know the holley run for about $200. ill soon be installing my 670 holley TB and wanted to upgrade intake to larger bore so it wouldnt be usless. i know the edelbrock will have to be bored. has anyone out there run both of these intakes and been able to tell a difference in the two?

[Don454SS]

My BBC Edel TBI intake cost me $252 at Summit. Go to the Summit website and see for yourself the price of the SBC TBI intake.

Don454SS: How tough are the emission laws down there in NC? Only reason I'm asking is I plan on going to Nascar Technical Institute sometime in the near future and just want to know what the do's and don'ts are like in that area so I'll be able to know if I have to leave the truck here at home.

Go with carb intake w/ a home-made adapter plate.

The factory intake is a piece of garbage, it doesn't matter how many spacers you stack on top of it, it won't fix the port design, you can port it but it still doesn't flow and the time you put in is not worthless and its just a waste. The biggest problem with your combo was the cam, that Edelbrock is a waste, if you would have put a decent cam in (2030 Crane for instance) your results would have been much better. There is nothing wrong with the Edelbrock intake but for anyone who wants to be forewarned do not buy the Edelbrock power package crap. Its funny if you look at there dyno sheets they claim 80 Hp and 80 lb ft of torque, yeah at 5000 rpm. The actual area where you drive the torque is nearly the same( never goes over 330 lb ft) and the horsepower slowly climbs to about 260ish. Now all this said that is their, heads, cam, MPFI TBI conversion, and headers on a TBI 350. Pretty pathetic power for the $4000 or more( for me anyway in Canada, MPFI is $1800, heads are $1700-1800, cam is $200, headers are $450) you put in, might as well buy a Whipple. Edelbrock blew it big time with that power package deal, especially for TBI. Now you can say well its a well balanced combo because no doubt someone will. Well thats fine, but for the price tag attached a new crate 350HO is nearly the same cost, add the manifold and yeah it will cost a couple hundred more but there you have a complete brand new engine with a warranty no less thats rated at 330 Hp and 380 lb ft of torque and even on TBI if its tuned right with a 454's TB( which you really should put on the Edelbrock MPFI manifold anyhow) that will be the power you have. For those who care, will it pass emmissions, of course, it just needs some decent tuning and to keep all the original emmissions crap that the original engine had. I know this is kind of a rant but still thats just my opinion.

Toughness ranges from bad to good depending in which county one resides. My county is no problem at all; about anything goes. The next up is Wake County (Raleigh) and they are fairly anal. The same for Mecklenburg (Charlotte).

so yal suggest taking the Edel intake to a machine shop to be ported, or can it esaily be done yourself? what all is required if you do it yourself? thanks for everything

You CAN do it yourself but it requires patience of steal, a steady hand, and a helpful, wonderful, and IMO the most inovative tool ever precieved by mankind, a Dremel (Man's 2nd best friend I believe). Dremel's price range goes from like $29.99-$69.99 at Wal-mart and you can get all kinds of neat attachments for it, I personally like the magnetic light they introduced since I have one and it works wonderfully. But if you don't feel like doing it yourself, then I guess you could take it to a machine shop and pay to have it done, but with the handy little tool, you could learn to do it yourself and save money and also help your friends out in the process. That's my opinion though.

[Badass69]

To port it I would do as suggested and just get a dremel and do it yourself. Basically the most you will do is gasket match and clean any flash anyhow. Boring it for the 2" TBI is something I would use a mill for, or something with a boring bar. I don't think anyone has a steady enough heand to accurately open the entire diameter by 5/16" evenly, I mean some might think they can but it won't be round. Porting is a do it yourself idea, and with practice is a good skill, trying to bore it if thats what you meant is a machine shop issue to do it right, plus take too much off one side and you will end up in the water jacket in the manifold, although same goes for the ports but there is a little more room for error there.

I am in the middle of putting a crane 2030 in my 94. When I was buying th cam an gaskets an stuff I asked about the edel 3704. He wanted 279.00 an told me it would add 4hp. He said I would never know the difference. I would glady pay the money if he had told me it was gonna be an improvement but for 4hp I think I will skip that. But if any of yall have added just an intake and got improvements please tell me before I get mine put back together.

[Badass69]

I think its worth more than 4 hp, who makes up these figures anyways, this guy a dyno operator or does he just pull them out of his ***. Its all up to the person i guess, would I feel 4 measly hp on my truck, no I can't. In all fairness I added headers at the same time and that combo really woke my truck up surprisingly. Now maybe on an entirely bone stock engine you may gain very little but on something with a cam and more mods it will be a noticeable gain. But thats just me and my truck, don't have to buy it, I did and I am happy. Oh and I am not one of those people who just defends something because they bought it. I have done some worthless stuff too, like my Hypercrap chip, the Helix TBI spacer I used to have and well for bad thats it, everything else worked.

[92swbsbc]

does anyone have pics of the holley intake on their truck and the brackets they had to fab up for it. how difficult was this. i think i decided to go with the holley to keep from having to bore it, and im a holley person at heart. besides, this intake was designed to work with the TB im puttin on. thanks

[lo-n-slo]

i have the holley intake on mine, no pics though. I wish i would have got the edelbrock. I had to "rig" the throttle cable bracket and also the vacuum hose for the brakes has to be changed, and the egr/map sensor bracket and coil bracket have dont fit right either.

[badburban]

I have the holley and I admit it wasnt a walk in the park. I had to modify every bracket and rebend a vacuum line for the power brakes but could have cheated that by just running a barbed fitting and then using a long piece of vaccuum hose but I didnt want to cheat it. I also had to rebend the ac compressor support bracket and then cut it down adn shorten it up then reweld it back together. Again could have cheated it by not running it but i didnt want to do that. My throttle cable bracket is perfect. As soon as you step on the throttle it opens. The pedal couldnt go up any higher. As soon as you hit the floor its fully open. I couldnt have any more pedal travel. Ive probably got 3-4 hours in the throttle cable bracket alone (Im kinda slow at fabbing brackets and welding). Ive got alot of work in it all and it looks nice. its something that only real car people will notice and be able to fully appreciate how much work Ive got in it. I mean everything is pretty much custom on mine. I fabbed up and built all my own lower and upper radiator brackets for my aluminum rad. There hasnt been one thing I havent had to modify on this thing. I like the challenge plus I can say yea I did that. Plus it does what I want it too. It looks completely stock to 99% of all people yet to the true car nuts they will notice and will appreciate it. But as I say for most people the edy is the way to go. I personally lprefer the holley but unless you've got a decently built motor it probably wont matter.
