Holley fuel injection

[Irondust]

I'm thinking about getting injected, which fuel system is best for a mild 360 buildup? The 2 barrell 670cfm or the four barrell 900cfm.

I'm thinking the same, Irondust. But from what I've learned on this forum and the mailing list, the Howell system seems to have more happy customers than Holley's.
As for your question, the 2bbl should be OK for a "mild" engine.
But don't take my word for it...

check their website. i think the 670cfm 2bbl is good for 250 hp or so.

I LOVE the infinite on-the-fly tunability of the Holley system. I think the dissatisfied users are purchasing the analog systems, while I have the digital system which REQUIRES tuning via a laptop. For instance, I've changed the configuration of my 360 twice since having purchased my Pro-Jection, but I've made adjustments without having to contact somebody to burn a new chip for me. My whole top-end is going on a 401 in a couple months, and again, I'm not concerned about it since I'll be able to do all the reconfiguring of the fuel-map easily and on my own.

To answer your question directly, definitely go with the 4bbl, but 900 cfm is overkill for a 360 (unless you're drag racing it).

the two bbl. is good for up to 275hp. that seems more than enough for my application. What is the advantage to having the 4 bbl. I found a two barrel at a pretty decent price.

I have the 2bbl analog on my mildly built 360. I love it....it sure woke up the engine.

I've noticed that Jegs has the Holley 2bbl Digital System for $770.

Questions:
Do you need a 4bbl intake for the system to bolt up?
What other mods does one have to make in order for this system to work?
Is it compatible with the TFI ignition upgrade?

you need either a 4bbl or a 2 to 4 adapter. just get the 4bbl and do the whole intake system at once. mucho better!

no other mods needed.

as long as the holley can get to a coil signal to tell it the rpms, its compatible.

thanks for the responses. The one I wanted sold. It was only 450.00 buy it now!!!! I think I'm going to be sick:(

[mccullough_89_GW]

there are always those projection units up on Ebay...

i got mine for $205 shipped!
when you buy the used system...buy the renew kit for that model...[$35 @ autozone]...in comes with all the gaskets and a new regulator valve/spring...
I messed around with mine until I bought that kit, and everything went fine from then on...

I LOVE my holley, its on the stock intake via 2bbl adaptor....can't even remember what the old 2150 was like[except that it sucked]...
but if you got the scratch' then buy a howell?

Appoximately how long does it take to install the 2bbl analog version?

[mccullough_89_GW]

initially just a couple of days few 6-8 [depending] hours each day....

considering new fuelline[bending/cutting/bending mounting], removing carb, cleaning intake, routing fueline, mounting new fuel pump,removing old..
connecting all the wires, running them through the firewall and around the engine....tuning the unit....

its not really all that complex of work.,..
it just takes a while to to everything...

[Aaron]

Does it run like a factory fuel injected vehicle? No stalling, no issue when its 5 degrees out?
Sounds like a good setup. My carb will probably need to rebuilt by next winter. I'd probably just get a rebuilt one from napa or autozone. They are around $300, so the pro-jection at around $800 seems like a pretty good deal.
