Project "Iron Man" underway.

Well I am finally getting to start my Iron Man project. I have a pre emission 460 with D3 heads and the low comprression. I am gonna massage the heads and the 4 hole square bore dual plane piece from the factory. I am going to see what this cheap combo is gonna do.
I am getting the heads worked to install roller rockers and guide plates. I had thought of doing a hydraluic cam but I think I am gonna stick in a good little solid flat tappet setup. Use one of my holley 750 carbs and run it with a stall I have and let her rip. Should be a decent powerful bracket toy till I am able to install my big toy. I even checked the rod and main bearings, they looked a little worn out so I am gonna replace them and should be good to go.

Funny thing is I might like this motor so much I might not wanna take it out.

Paid $300 for motor and C6 trans. Ran good, no smoke or knocks. The trans has never been off of the motor. A old man had it in a car and only drove it every 5 or 6 months to run it around a little.

300$ motor is the best kind! go beat on it and have fun.

spend the few hundred dollars and find a set of early small chamber heads. Especialy if your going to put any money in the D3's.

I had a hard enough time trying to find a decent big block ford that someone would part with. This is kinda of a test for my skills and knowledge for me to see what my results are. All I have to do now is find out how much lift I can go on the cam without having any PTV clearence trouble. I will be posting up some pics and the build items as I go.

Timing and duration has to due with P to V not the actual max lift.

You need to watch retainer to guide / seal clearance, typical .535 to .540 is about it.

You trying to use the old pistons?

Yea, the shortblock is in very good condition.

find some d0ve heads! you'll thank me later.

With a swap from d3's to small chamber heads will it run on pump gas?...

yep,and he should do the timing chain deal too if it aint been done yet.

Yeap...and a plate too. Might as well make it fun.

As soon as I get more of my plan together I will post up a list of specs and parts, might have it tomorrow. I will give better details about the motor as well.

that may be overkill. but...........125 hit would'nt hurt.

Ok here is what I have so far.....

I'm looking at some early style C8,C9,Dove heads doing my port work with the stock valves, Thanks Mr Hobbs.
Keeping the iron 4 barell dual plane manifold, with some port work.
Running a holley 750 carb.
New rod and main bearings in the shortblock
Building some 1 3/4 in shorty or mid length headders.
Lunati cams, a couple to choose from, here is the one I had in mind...

ADV. 276/286
@.050 247/256
106 LSA 100 ICL
LIFT .630/.637

I am guessing my compression should be around 9.5:1 but all in all I think this should be a fun modded stock style motor.

I would get a cheap used aluminum duel plane....dont waste your time grinding on a stock iron one..

I know, this project is to see what I can do with the factory stuff. I am more or less gasket matching and smoothing out the ruff areas. I am spending the money for the A-headded beast so I rather be buying stuff for that.

Thats to much cam....... Get down in the 230's on the intake. I also assume your not expecting to run stock rockers with that kind of lift. Look at Lunati 61603.

That cam is a solid flat tappet That is the biggest one... here is the other one I was looking as well, it's smaller too.

OF course I am still keeping the idea of building my own cam. I love how I can browse this forum and read what people build and see results, and with all the information from a lot of people I can get good ideas on how to setup a motor. I built the last cam in my SCJ motor and I got almost a tenth faster and another 2mph with a nitrous built cam from the N/A cam.

Still a little on the big side.......... for a 9.5:1, Factory intake motor.

Okay, aside of camshaft selection. I have the shortblock reassemblied with new rod and main bearings, A full gasket kit sitting in the truck. I also have a new hi-volume oil pump. I even went out to repaint the block the orginal color, old ford blue. I squirted some aluminum paint on the intake manifold. as well as the heads when I get them. The valve covers are orginal blue as well I need to post some pics so far. I have done everything in house. I have decided on the camshaft I am going to break down and build my camshaft for this thing, after all I want this to be a decent setup.

Get the Lemster to get a cam

to big a cam for what your doing....

I think that 1 3/4" headers are "marginal" at best, and would definitely be a "bottle neck" to future power improvements. Your headers should be at least 1 7/8" / 2".

So weather a big block is all stock or modded it still would require good size headders? Thanks for the tip because I wanna redo the exhaust on my F350 sometime in the next 100yrs.
