So i have a maf tpi set up but i have wanted to do somethimg new to get at much power out of as possible and i think it would be kinda cheaper. So my idea is to take like camel hump heads or the old school real power making heads with a carb intake then with out a carb have it bolt into a intake pipe in the intake pipe there is a 3" butterfly valvethen goes down to my maf and into a cold air intake. this would cause the least resistance with no trottle body and just need to tune the tpi computer. What are your expert thoughts?

 

Also what would I need to do for injectors?

 

are you talking about something like this ?

 

There are no real power making old school heads

 

or

 

Kinda like the first one but not exactly, and when I say real power making heads I mean like double hump heads on like 327s... If I do this i would also go 350 block. but what i was meaning is a pipe with the 3" exhaust brake from a diesel or a pvc pipe with a butterfly valve in it. At my work there is one used for displace on how a exhaust brake works and i think it would work.

 

so true!

 

ok I just thought the 202 heads from the late 60s were pretty good but my nistake. would everything else work tho? would I be able to have a machine shop drill in for injectors and would everything still work right

 

hmmm I didnt think of how to do the trottle positioning sensor any suggustions for that?

Not saying this exact one, but what your describing is already made. There are several like this.

 

you can use a ls throttle body not the fly bye wire older ones, tps and iac.

 

hmmm thank you its not exactly what I was thinkin but may work! If I did my own trottle body in the pipe I will need to learn how the positioning sensor works.

 

Yes that is what i am looking at didnt think of that had thought of just "custom costum costum" on my brain when they already kinda have it haha. what do they call that elbow so i know what to look up.

 

Best bet for simplicity sake is ls1 throttle body and sensors and cable from 99-02 fbodys and then elbow like pictured above. Single plane efi like victor e efi since its 1204-1205 port out the box and would fit old school heads well. Some other brand intakes are 1206 port and would overhang the head port creating a large step in the flowpath. Not great for airflow but it may not hurt too bad on lower hp applications.

 

Professional products EFI intake is pretty inexpensive so no need to do the machine shop work on a carb mani. IMHO. EBay TB's are reasonably priced now. Accufab comes to mind. EBay fuel rails. Rebuilt injectors from FIC would keep cost down.

Some day I will give this a go.

 

Alright i wasn't going to go near trottle body inj cause my tpi is better then that but I was just thinking of like a high rise intake manifold for a carb into a pipe with a trottle body for high rpm's and keep the tpi stuff just reprogram everything. I knew that was a ls trottle body I meant what is the elbow? a carb elbow or intake elbow? If I ebay'd or went through a parts mag what would the elbow be called?

 

 

your dreams came true lmao, and now for the low low price of 3k you get the vacuum ports plugged with jb weld for free. atleast this intake has the rear coolant crossover going for it

 

O god I mean better for rpm's then my tpi not a tpi with worse rpm's haha I am looking for the opposite where the carb intake is the bottom for great rpm flow just exactly like the first pix you have almost.

 

Only two elbows I have seen are Edelbrock(many sizes see site) and Wilson. I think a 4B TB with 2.00 inch bonnet may afford more clearance? Not sure on that.

 

6061 used to make custom sheet metal intake elbows for 225. I am running one on my car. I think they still have sheet metal intakes available to buy (fit ls1 fbodys with low rising elbow and some other generic ones) but not sure if they do custom ones to your specs

 

old school..yes..But it works!!

 

I think This maybe the best with a high rise thanks everyone for there help!

 

Thats kinda what I'm doing I have Edelbrock #29135 with Edelbrock #3848 elbow and gonna run a LS1 throttle body on top of mildly worked Vortecs. Running a 10.0-1 383 small block with XR282HR camshaft. The way your wanting to do would be next to impossible getting a TPS to work IMO. Everyone else is pretty much right about no old school heads making power Vortecs were the best stock SBC head ever made.

 

This is exactly what I've been contemplating on building for replacing my TPI manifold by using a hurricane efi manifold and building my own TB elbow since arizona TPI is outta business.

 

How would using the maf inj lines and everything from the tpi not work just not the heads and the intake? the heads and intake are the only things that would really be changed and they dont have any part of the computer. I would have to just get a really good tune on the maf ecu

 

Take your TPI intake base and grind the runners open just to the inside of the fuel rail hold down bosses. This takes the long restrictive runners out of the equation and allows you to keep your factory injectors and ecm. You will have to weld a box around the ground runners and top it off where a 4150 throttle body would bolt up. This allows it to stay tpi fuel injected with all sensors. You will have to add a throttle body but that is the only thing aside from some welding. Similar to an old smokey unick crossram intake with a single 4barrel or you could get fancy and add a second throttle body making it like a 69 Z28 crossram intake.

 

That doesn't make sense why I couldn't use the tpi ecu and everything and do this. There is no sensors or wires that go in the intake or the heads from what I know of. So if I say dropped a 400 with this intake and camel hump heads or even vortec heads why i couldn't use the maf, trottle body, and o2 sensor to make it work with a tune its not a map system

 

They were good heads, in the 1960's. Technology has come a long way since then.
