It can though. Your 7747 bin can be "patched" to have hiway cruise. You are looking for Hiway747.zip.

gmc406, any pics of the engine?

I try and take some today. Thanks for asking

[gmc406]

Got them. How do you post pics on here?

Sorry 93blazer383, my intentions were not to highjack this thread.

[Blue71]

The best way is to get your self a photobucket account.
http://photobucket.com
upload it, then copy and paste the IMG code to your post.

Here we go:

fuel rail

injector-I think the blue rib shows it's a 19lb/hr injector.

self explainitory

[gmc406]

Fuel press reg.

[Blue71]

Ya, 19# injectors. look like the stock Edel setup.
big tube headers, non vortec heads, non angel plug, what heads you running, stock Throttle Body ?

Edelbrock and a Holley throttle body.

Hey, does anybody have any picks of their adjustable regulator? How does it fit?

Nice pics. I have an adjustable regulator but no recent pics. I'll have to take some and post them. I still would like to know your mod list and drivetrain set-up, but when you have some time. Not many people running in the 12s around here. The Edelbrock MPFI intake has been scoffed at as a performance piece on this board in the past. Obviously with the right combination and tuning, it works very well. I think the extra cubes help too, mind you, and probably generating huge low RPM torque numbers. BTW, Wester's lists the 19#/hr injectors supporting 225-300 hp: http://westers_garage.eidnet.org/tec...info.htm#cat11. I wouldn't be surprised if your engine BSFC is below 0.45. A few extra #'s in those injectors may give you a few more ponies.

Here's my engine taken a couple of years ago:

[Blue71]

Not real easy to see, Aeromotive regulator.
I'll get a better pic later.

LT1 style regulator, If I did it again I would just buy a new right
side fuel rail, threaded on both ends.

[xx_ED_xx]

Well If I can hi jack a little here.
I am using the ramjet style pcm on my setup
Someone that knows about tuning.
Could I add ve tables or do I need an O2 sensor to be able to do that?

[Red94Chev]

Blue71, looks like you had to modify the rear of the fuel rail to mount the Aeromotive regulator. I shyed away from that unit because of clearance issues with the distributor, but I see you found a way to make it work. I used the smaller Holley unit and mounted it on driver's side. I had to reverse the fuel rails, but I can't remember the details right now. I wrote it up in a post somewhere.

ya, It's not the cleanest install but it works.

It would have bolted up in the stock location but was a very very
tight fit.

94Blazer383 had a nice setup on his boat, reversed the fuel rails or
something, there's a pic on the board here some were.

Been following along here and had a couple questions for y'all.

gmc406: What's you 1/8 mile time? All I have around here is 1/8 mile tracks, and I just wanted to compare. My truck does 8.90's with cold air, 9.00's with hot air.

Red94Chev: Did your truck come stock with the accumulator cozy or did you add it. Recently got the air working on my S10 and I think something like that would help with the AC performance.

Thanks

Also here's a engine pic.

If I remember right, it runs somewhere around 8.25's......cool valve covers on your mill.

Nice and clean, it looks good. I wish I could've cleaned up mine a bit, but I was in a hurry to get the pics up.
I hear what your saying, I saw that too on his site. That's why I'm soooo confused with this whole injector size thing. I would like to feel safe in saying I'm over the 300hp mark. I would like to think too, that my engine doesn't require a lot of fuel to make power. That could explain the good fuel millage.

Dam*, that's a fast truck, your definitely more that 300HP. I estimate mine to be around the 360 to 375 mark but I could be wrong. My exhaust is really hurting my HP right now, with a better exhaust it might be close to 400HP, but I'm using 29# injectors. ET wise my too tight converter really slows the 60' down. With a more appropriate converter and better exhaust, I was hoping for 8.50's. Did you do any porting to the manifold? Mine has some minor work, which was difficult given the tight working conditions.

[94Blazer383]

93v8s10, thats a nice setup. you hardly ever see guys keep the air on s-10 v8 swaps. Yes our trucks come with the coozy on the AC accumulator.

[93V8S10]

Thanks, I'll look for one next time I go to the j/y.

Those center bolt valve covers look great. I wish my engine was as clean as yours and Red94Chev engine.
