Hey guys. Just looking for some opinions.

I have a 68 Charger I'm wanting to go protouring with. I have a non original 68 440 in it now and this is what I'm planning

440 block with half fill
440 source bottom end, factory stroke and 9:1 comp
Billet mains and maybe girdle
440 source stealth heads, ported and checked

Pro Flo Xt efi from edelbrock. High impedance replacement injectors for 1000hp. Can use 2bar map sensor and optional wideband a/f sensor.

F1 from the supercharger store. Air to air I/C

Looking for something I can play with on a budget. Turbos are fantastic but I don't want to have to deal with exhaust plumbing and I am not out for all out hp. Car will be street driven mostly, and I'm planning on going with a gear vendors and 727 or possibly a 4L80e, and 3.55s out back.

hmmm...

1000 hp
billet mains/girdle
cheapest heads on the market
Edelbrock EFI
4L80E transmission
Pro Touring (looks purty but will likely never see a race track)
Working on a budget

Some of these things do not fit together.

Don't need expensive heads to make more power than my tires can handle with just a little boost. And by budget I mean I'm keeping cost in mind but it's not the biggest concern. I don't plan to autocross but I do like tight handling and excellent brakes. It will truly be for pro touring in that I'll take it on the same road trips I do now. The goal isn't 1000hp but I'm going to have the fuel if I need it

I enjoy tweaking and am pretty good with electronics so I want something to toy around with.

Is there anything I listed that is a roadblock or weak point in the build?

By the way, I appreciate the help feets. I've been following you on here and turbomustangs for a long time.

I hope you realize how difficult it is to hook up big power with low profile tires.
I run a 295/45-18 which has a 5" sidewall. That tall of a tire still has issues holding on to my mild build with 3.23 gears and a stock converter. Adding another 350 or 400 hp would make it even more difficult.

A car like you're describing (I hate the term Pro Touring) is a compromise of EVERYTHING.

Good power but a fat power band.
Stiffer suspension but not harsh.
Sticky tires but wear and all weather traction is a concern.
Strong drivetrain but nothing that bangs or slams on shifts.
Stiff chassis but it can't rattle your teeth out.
Lighter weight but keep creature comforts.
Blower hanging off the side of the engine that doesn't interfere with the A/C compressor.
Big brakes that aren't harsh and have readily available replacement parts.

Sure, you can hack it together like I did but be aware that you will have to give a little here and there to make it work.
Cars like the Big Red Camaro are nifty but have more money in them than I spent on my house.
Like anything else, it's a money game.

I'm no stranger to high hp cars and trucks, I've got room for 345 width rubber. Something like a Pilot Sport PS2 in 18" out back. And drag radials for our local street legal drags

Like I said money isnt the biggest issue, but I'm not going to throw money at parts that aren't worth it. Maybe it's because I'm an engineer but efficiency is number 1 in the build.

For example, I know I could make that power with my ported 906s but I want to get some weight off the front. And the stealths are cheap. But I can't justify an aluminum block.

If you forget DIY efi stuff like megasquirt, what would you choose for efi right now? I've considered fast, dfi and ended up really liking the pro Flo when I saw it demo'd. Plus i like the design of their intake.

I've been looking at the FAST and Pro-Flo systems but I don't know enough about them.

I can't afford to make any changes so it's not a priority for me.

the 440 rods and crank would be my concern if you're planning over 1,000 hp.

I have the tyres you mention 345 PS2's. Pic:

Don't buy injectors that will support 1000hp unless you are making 1000 hp or close....

Injectors must be sized to the HP you will actually be making....

Also...making big power anywhere close to that, you better get an aftermarket block.

I disagree. What HP do 83lb/be objectors support at 60psi?

I have run these for years, just curious where you get that fact from.

Its the idle concerns for big injectors on a smaller engine, I also have 83's on a mild 500 inch (prior to the procharger). As long as you have a good charging system, you should be good with the larger injector.

I must be dumb, I just don't understand the logic of making 1000hp or attempting to do it if you're not going to run/beat on the car. You'd be better off and happier w/ a mild 650hp boosted 440 and you won't need all that fancy EFI or other junk. My Bro-in-Law spent about 12k on a 408 storker for his Fox body, another 10k on chassis and ground effects plus paint and he won't race it..."doesn't want anything to break". Then why spend all that cash on the drivetrain when a modest 5.0 would have done...

Because on the street you'll be far happier with EFI than with that carburetor junk.

Yuck, your piss poor attitude is showing again.

I'll be running 16 x 95lb injectors.
The pulse widths are very narrow @ low engine speeds/loads with large injectors and I don't want a poor tune.

Enough for 1174 hp at 85% duty cycle.

I'd not worry too much about the injector size, some folks on the turbo dodge team are running 130 pph injectors.

My Reliant starts and idles like a stocker and runs stock electronics.

Yes, I do my own calibrations.

I could be wrong....and you are more experienced than I. But I would be concerned that if injectors are WAY TO BIG...you could have idle pulsewidth issues. This was based on my assuming he meant run like a 650 hp engine on 80lbs injectors. That would be like a .40 duty cycle or something...

Maybe it's not a big deal for a street car... But it doesn't sound ideal to me. But I was assuming a lot....

I run a 4 banger with 83's and friends of mine run 130's. One just ran 8's with a Dodge Shadow.

His injectors will be fine, hell I use to pass state emissions with no cat with 52's.

People talk theory all day, some of us do actually walk the talk and can provide feedback.
