ive reseached the topic and from what ive seen at this power level it is worth about a tenth to two tops going from a single four with a dominator to a t-ram with two fours.ive seen bigger gains with stock headed combos just wondering if its worth the effort in my application. first alittle about my combo

528 indy alum low deck -1heads ported by modern 375/297
13.3to1 comp roller 704on both/283/288@50 108sep in @ 108
indy 400-3 intake with 1050QF dom just port matched
custom 2.25headers have TTI 2-2 1/8steps to try also
727 9" 17509Jconverter approx 5500stall(have a 8"6000stall to try) dana 60 4.56s 31.5"x10.5W MTs
70 cuda mini tubbed ladder bar has ran a best of 9.45@142 so far @3500lbs with only a handfull of passes so its not maxed out.

is it worth the $$$ to do the switch?and what would you reconmend for carbs?dominators worth anything over pair of 4150s??
i think i know the answer but if i can get this to run 20s id do the switch

I`m going t-ram next........better distribution and looks bad azz to boot..............I`ll go 2 750`s more than likely..........

ya no question about better distribution thump im more stuck on what carbs i would use???im looking for max gain but i also like alittle bit of streetability.....would dual doms be worth it?or pair of 1050 4150s be close enough?has anyone played with this???

I am looking to do the same on a 604" motor, and I have a stage V Dual quad intake on the way...thought about 2x Quick Fuel 1000 or 1050 4150 carbs for it.

Just have to decide on Annular or standard boosters...still have to mount them sideways, and the car/engine will be street/strip, but I figure the 4150 would be more streetable.

Not really a tunnel ram, but I want it to fit under the hood.

Go EFI on the T-ram. Then your ready for a power adder

[quote=FastmOp]Go EFI on the T-ram. Then your ready for a power adder [/quo

alot of changes to go that route would have to be really worth it......fill me in on the details.

I run EFI on a Indy single plane on two different combos. I use FAST but there all good. Fuel distribution is the best and an injector sprays at 45psi

I was gonna do just that.. I had the parts to do
either a W-2 or W-5.. but I changed my mind only
because I didnt want to cut the cowl hood and have
the throttle bodies above the hood.. mainly for rain
being a DW car.. I have 2 extra throttle bodies and
the tunnel rams for each set up.. I bought the Holley
multi point EFI and went with a single plane... really
all it would cost IF you wanted to go injected would
be the extra throttle body.. again IF you have the TM

We made a few mistakes on ours but all will be good in time

i have nothing Mike...........so need fuel system the whole works....im not opposed to it just wondering if its worth it.

I assume you have a TR.. but if you werent thinking
of injection then its gonna cost about $2300 to go
with a TR and injected.. its a bit pricey on the hit
but I did it.. for the single injected(single plane)
its more like $1900 for the complete package... it
has its bennies

You will be able to use a remote start with EFI lol
It will drive better, it will make more power and you will love the car cause you don't have to babysit two carbs.

remote start....im sold LOL
ok next question what system is reconmended?

Where you located? I'd find a guy in your area. It's popular enough that tuners are everywhere. You get what you pay for. I have used FAST and dabbled in mega squart.

I went with Holley.. mainly because its a self learning
system.. but it also has data logging

I`ll never jump on the efi wagon cos I`m not a quitter and love the challenge of making carbs work..........easy no, but I don`t buy the "efi makes more power bs" look at Pro stock. Carbs cool the intake charge better and make more power up to a point so in your case find out how much cfm you need and have a couple built by who ever.............

thx guys... im in ontario canada i know a tuner here that did the wifes stang(662rwhp)but im open to options ...i also know a guy who ran megasquirt with pretty good results i guess ill do some inquiring.

I talked to Ray Barton last week, and he told me that a direct injection intake and the new Holley EFI is the way to go. I asked him about The FastEfi, and he told me that the direct injection is much better.

I was talking to him about mid height TP intakes and the Stage V intake, and he told me buy the Edelbrock single plane with direct port injection...but, I like my old ways, and chose to go with the lower Stage V intake, and and then contemplate running modified 800 cfm Edelbrocks (modded to 1000cfm) or go with the Quick Fuel Q-Drag race carbs.

I guess I am in the same boat as Thumperdart.

Big cubes, big cam, big converter. I think you are going to need more than dual 750's. 1050 Dommy's might be a little too much, but somewhere in between. Maybe a set of 950's?

Dom.. you do know why the HP is lower on them..
its not due to efi... its the lack of rpm.. like
1500 less... some day you will join this century
