Nice.

Thats a great deal of work. Was there a reason you chose to build it from scratch instead of purchasing a manifold and fuel rail premade for this?

hessdawg

the first reason was money
china knockoff $250-$300 fuel rail kit is $200-$250

second the injector angle sucks on all the pre made stuff

nonhog

Awesome! Engine specs? Whats it going in?

hessdawg

old 455 bored 30 over 9.5to 1 compression. forged rods and pistons. all the casting numbers were ground down on the heads so I have no idea what they are. nodular crank. gotta get cam specs. port matched intake and heads. magnum rockers, jomar stud gurdle headman headers.

its going in my 78 trans am

gearheads78

Nice!! What system are you using to drive it?

507OLDS

Do you have to run the spacer so the linkage clears the rails?
Have where does the tip of the injector sit in the runner.If it is up inside the bung,you need to move it down.Otherwise it will spray the barrel of the bung,then drip down into the runner.You want the tip of the injector to be flush with the roof of the runner.Looks great so far.

hessdawg

thanks for the tip
since i angled the injectors the bottom of the o-ring sits right up against the manifold.

i will br running a megasquirt to control fuel and timing

gearheads78

Sweet....please continue to share the progress.

507OLDS

Do you have a picture of the runner showing the injector installed?

66ninetyeightls

Are you building the megasquirt controller yourself? What version are you running?

hessdawg

shoot i thought i took a pic but i guess i didnt

hessdawg

havent bought the ms yet
I really want to build a ms3x but we will see if the funds permit

oldcutlass

Interesting!!! Waiting to see how it turns out!

66ninetyeightls

Having installed a few of these over the years may I recommend having someone do the tuning for you. It is a real PITA and it doesn't take much in the wrong direction to damage the engine.

hessdawg

got the valve covers on

got fuel rail mounted

got injectors wired and pcv run

I hear you. I just converted my 92 zx7r ninja to efi, and i would have paid money to to have a tech line to call. lol
i wish there was a local tuner that was familiar with ms

ah64pilot

That is BA! Is the EFI a fuel mileage thing or a power thing or both? It seems like a lot of work but it is definitely going to be one-off! Looks really good! I love the valve covers, wish I could spend the money on some like that...chrome will do for now.

hessdawg

i got the valve covers off ebay a few years ago then some guy was building them for $197. they fit pretty good too

66ninetyeightls

Very nice. Where did you get the throttle body? That thing is going to look beautiful!!! Shame to start it up and get it dirty!!!

hessdawg

the TB is an MSD they stopped building them a while back
i think i got this one on ebay got $250

Vega

Wow, i may be a little slow on the draw here but thats some amazing work you've done
Ive seen a few EFI Olds 350s running around but its pretty rare to see a 455 with it, its something ive been wanting to do with my rebuild. Ive always wondered how good i could get mileage while still pulling monster big block torque xD ive heard of people on here pulling 15mpg in the city on built 455s, thats getting dangerously close to my 3rd gen camaro's dinky smogged TBI 305 0_0 hell id do that swap any day haha

Let me know if I can help. But I have to say I'm not a real MS fan.

Thanks

hessdawg

hey mark
i would love to do an accell kit but i just dont have the $2000-$3000

the only way i could do it is if they sponsored my car
but i don't know if they do that

cutlassefi

Based on the fact that you pretty much have everything else all the elctronics are $1850.00 with a wideband. That's ECM with a base tune, harness, and the wideband as mentioned. Imo head and shoulders above the MS.

Thanks

Hessdawg, What a NICE Build. I run Megasquirt on my 76 BMW and I'll be going full sequential spark and fuel with it. I also have a 62 Olds 88 with a 394.

Couple of questions, what did you do for spark control on this engine?
I'm new to olds, so trying to figure out my options for crank pulley/pickup arrangements. I probably will end up having to have something made up.

how did you manage fuel? In my BMW I was able to use a high pressure in-tank pump that fit from another model, so it was easy..

Cheers!

hessdawg

hey thanks
i am running an ms2 right now and an edis8 for the ignition as you can see in this pic lin the lower right by the crank pulley i have a 6.75 inch 36-1 wheel and a ford crank sensor

heres a closer shot
c137f965.jpg

you can see in this picture the cop set up
96212bca.jpg

and this is what my edis wiring looks like so far

edis8wiring.png

i also converted the distributor over to a cam sensor so in the future i can run full sequential. but i do have i question for you on the cam sensor? should the single tooth be pointed at the pickup with the engine at tdc 1???

0981b2ee.jpg

cutlassefi

That depends, he much injector timing adjustment is available on the MS?

bmw2002e3

Wow! You basically just answered my question and that's what I plan on doing for ol beulah. (62 dynamic 88).

Yep, on my BMW the sensor is triggered at TDC 1. I drilled the upper timing chain cover and stuck a sensor in there. you want to be sure there isn't much room for play and those bosch distributors and the gear arrangement bmw uses on those cars flops around a bit. Your setup looks sound though.


Thanks for the info, and the wiring. That'll get me on my way to figuring out my install.

cutlassefi

hessdawg

Yeah I'm not 100% sure the edis will work the way it's wired but fingers are crossed. The motor is back out on a stand and the old Holley 4d is back on to breaking the new motor. Cause it was pre programmed before the motor was rebuilt
Hoping to start it next week
I'll try and post a video

bmw2002e3

I'm not trying to be contrary, but I am curious, in what ways?

Obviously a pre-built unit is easier, but i'm thinking feature set.

Also regarding your comment to cam tdc timing signal. I thought those had to be pretty static, when I designed mine, I followed what I saw on other newer cars, usually something coming off the cam, and non-adustable. Flutter from a distributor gear won't be an issue? That's good to know, as I know some people in the BMW crowd find it easier.


Cheers!

bmw2002e3

Good deal. What coils are you using?

hessdawg

Coils are from a 6 cyl lincoln ls also the jag xkr not designed for edis but they are 12v

cutlassefi

Download the software of each and compare. If you're only going to run in a straightline then the MS is fine. If you want the best driving vehicle you can get in this price range then the Accel is far and away better. Why? Simple, because for one it has twice the transient fueling tables the MS does. There are other things that set it apart as well.

You normally change injector timing in 30 degree intervals, so a sensor that varies a few degrees here and there isn't critical like it is for ignition.
Hope this helps.

bmw2002e3

I'll download the software and take a look. And thanks for the explanation, that helps quite a bit.

hessdawg

Hey BMW
I might have to Skype you when I get this thing wired for ms.
It's always better to have somebody that has a little more experience than I do

bmw2002e3

Sure thing!

hessdawg

ok working on the edis

will olds 455 start with 8-10 degrees btdc??

cutlassefi

Yeh why not?
