574 Horsepower/583 Ft/lbs Torque,  pump gas , 750 cfm carb, Torker 383 Intake, "all in" by 5700 rpm.

Will scan, and get the actual dyno sheets up later. This was a relatively inexpensive engine to build, and easy.  Whats better, is the Torque curve starts @ 3500 rpm at 542.3 Ft/lbs, and stays above 500 ft/lbs through 53-5400 rpm ? I forget already !
Enough to motivate ANY heavy "B" body.

Check it out, I'll get more photos and details up later.

Dunno, what you'd spend, you'd have to talk to your builder 'bout that one, I'm sure he'd give you an estimate.

My Customer supplied some used EDDY heads, and a Torker 383 Intake, Thats it, That's ALL.

I supplied the rest, block, crank, Rods, Machining & balancing, etc.

I guess I should also get a "parts list" together, as to what was used in this engine ?

As well as the dyno sheets ?

Would this be helpful  ?

You fellas can price your own parts from where-ever, Machining, Porting & Balancing estimates from "your guys".
I've been posting photos of the Short Block, Crank, Heads etc., as a guide already.
Go here for a look if interested further;

The Camshaft is our own "custom grind" from Comp. Cams. It is a Flat Tappet, solid lifter.

It is NOT proprietary, just a matching of lobe profiles from the existing Comp. databases, based upon our experience, building Mopar Race Engines over the last few decades.

It is NOT a fast ramp .904" lifter Diameter, and, It is EASY on springs and parts, as this is a "street" engine designed to live a long time.

I will supply the specs when I get time to scan, and post the dyno sheets etc.

It costs the SAME money to have a Cam ground, as buying one "off the shelf", the ONLY difference is the few dollars more freight, and about 2-3 week wait.
ANYBODY tells you different, WALK AWAY !

Yep, custom is the only way to go, especially when you have a dyno proven combo and years of experience like Bob has.  :icon_smile_big:

Ok Bob, quit slacking  :nana: :haha: and post those flow numbers, cam profile and dyno sheets !  :scope:

I bought a scanner. ANYBODY got a "quick lesson" I can reference on how to post, after I scan ? Posting from scanning ?

Other than that, I'll take photos and post, I got "that" figured out !  LOL !

as you know I'm thinking on make that stroke with JUST stock parts including torque converter ( 452 heads, 400 rods, stock camshaft, etc... ) trying to get an iron casted crank to keep same balancing and stuff around... that would be IF I find a crank locally. Of course only buying non stock the pistons. I want a complete sleeper. Maybe just mill down a little bit the heads and installing metalick gasket. Can I get something similar on HP and torque, and completelly streetable ?

Nacho, i would use the 440 rods, this way you have a lighter piston, for the extra, you might as well get some good after market ones from 440source or Muscle Motors, i used a 69 crank & rods from a 440 for my 451 with the ross F/Ts, it didn't take much to balance out, but i got these parts on a trade, so i wasn't out much (just an intake) i spent about 250.00 to have the crank done (counterweights cut down & turned 10/10) for the money, you just can't beat the stroker kit, 1199.00 & you get crank, rods & pistons.

I have beeing searching a 440 crank for years and didn't find it... so I have to get it first. I have found complete 440 engines from friends, but I don't want to part out those.

if you think I'll spend $1200... think on international shipping ;) and I'll get double of that :P. plus machine job

Just wait til your friend visits Connecticut again and have the kit delivered there and then your friend can bring it back.
