engine advice - 400 block
Hey guys.. I ran across this block on one of my local websites. Some guy is trying to unload the following. I have wanted to drop a 400 block in my car ever since Jesse started posting up his incredible times. Hopefully he and Corkvette will chime in after bit. This is everything I know about the motor so far.
400 Small Block 509 Casting
.030 Over
Line Bored Splayed 4 Bolt Main Caps with ARP Studs
Decked
ALL FRESH NEVER ASSEMBLED
3.75 Stroke 5140 Steel Crank *New*
Clevite 77 H Main and Rod Bearings *New*
6.0 H.Beam Rods with ARP Bolts *New*
JE SRP 4.155 Bore Flattop Pistons *New*
SpeedPro Hellfire Rings *New*
Scat 168 tooth Flywheel Internal Balance *New*
6.75" Internal Balance Dampner *New*
ALL PARTS NEW
ENTIRE ASSEMBLY COMPLETELY BALANCED
WITH ALL RECEIPTS FOR MACHINE WORK.
The guy is asking $2,000obo..
Would this setup be ideal for a daily driver utilizing either the superram or single ram intake? Is the price fair?
Any input is welcome... Im not to serious about it unless its a real deal!

HUH???
What the heck does the rod length have to do with the compression ratio and combustion chamber sizes?RACE ON!!!

OK guys... there is a large possibility that I will be buying this motor with the rotating assembly.. My question now is... With a mild cam and the superram or single plan intake - what kind of numbers would I expect to see. I would want to build this motor more for an auto-xing car rather than drag. What would/ should I do to get this motor to be at that level.
Any advice welcome!!

Too bad it's so far away, I'd snap it up! Wouldn't worry about hp #'s on a 406. You'l make all the torque you need and then some for auto-Xing providing you don't overcam it.

CFI-EFI,
It is to my understanding the motor is not assembled, so its the block and rotating assembly.. Same thing i guess.. As far as level goes. I want to insure the internals will support higher RPMS, and around 400hp..

What do you consider "higher RPMS"? I'm shifting my factory original long block at 6000 rpms...no problems. 400 hp isn't so exotic. That is well within the realm of cast components. This is all forged. I don't understand your concern.

I looking to spin up to 8k... Im not very educated on the capabilites of forged components ect... It sounds like this motor has a lot of potential.. Perhaps i can aim higher that I want.

Gonna be looking at a hell of cam / head / induction system to see 8000rpm.
probably kill all the bottom end torque usefull for Auto X and idle at 2K!
Do you own a trailer?
You won't be driving it to get a burger

Why do you want to spin it that high? All of my 406s made peak power under 6000. And the last one was right at 500 HP at the crank. It was stock crank with forged Eagle 5.7 rods and forged Speed Pro pistons - nothing remotely exotic about these parts.
Witht the right heads, cam, and compression ratio, there is no need at all to spin a motor to 8K unless it is an all out race motor. A motor that sees that RPM with regularity WILL need freshened more frequently.

I am almost positive I will be picking this motor up sometime next week. I have to arange transportation for that is an issue on my part...
I can hardly wait!

You will have a hard time finding an intake manifold that will support much more than 6500 rpm. Superram manifolds will not go much past 5800. Before you cam an head that shortblock, ask alot of questions and build accordingly. Bigger is not always better. build for torque or build for horsepower. Factor in the components (drivetrain etc) that you have or intend to run. Making a fast car is like baking cookies. The recipe(or combination) is more important that the ingredients.

Find out the part number of your pistons and talk to the mfg about what compression they'll make with various combustion chamber heads (and find out of the block as been decked and how much). You'll then have an idea of where to start with the heads. Talk to cam and head manufactures too and be very honest with you goals. One of the most common mistakes is buying too much flow on the heads and/or way too big of a cam and then the car won't work very well. The key to performance is a finely tuned combination. And the key to your happiness is a motor that runs like you hope, with minimal adjustments needed.
With a 406, it will not take much to get 400+ HP. Like I mentioned, I was right at 500 with a 11.5:1 CR 406 with un-touched Sportsman II heads, a Lunai 550/571 mechanical flat tappet cam, a Victor Jr. intake, and a good 750 Holley.

I am sure I will have plenty of questions once I learn more about the motor. As far as intake goes. Would a carb be a better idea for auto-xing, or should i stick with fuel injection?
