New here, I have a 440 that I bought from a guy, says it runs, but looks to be mostly factory, if not completely factory. It's a later block, '7? don't remember exactly what it is right off hand. Anyway, I'm wanting to build a nice cruising motor with some oopmth to it. Here's what I'm thinking;
-Factory block + .030
-KB pistons: # KB237KTM030
-Factory crank and rods (I would like to run ARP hardware though)
-Factory heads, not sure on which ones that are on it, but based on the year, I'm thinking that they are the 42 heads.
-Hydraulic flat tappet cam with matching springs (if I can get away with reusing the factory retainers and keepers, then that would be a plus)
-Would like to run a double roller timing chain
-Will be running a bigger oil pan with matching pickup, keep the factory size pickup tube
-Brass freeze plugs
-I'm thinking that a 750 cfm carb will be fine for this motor, I have an old Holley sitting around that I can use, am thinking about going to a 1" phenolic spacer 4 hole
-Mopar electronic dist with either orange or chrome ecu and MSD Street fire wires with Autolite plugs (have a new set from a previous car sitting around)
-Mopar Performance aluminum water pump with Milodon HV water pump also aluminum
-New flex plate, 727 will be behind this motor along with 8 3/4 with 3.23 gears for now
-Stant 180* t-stat I think will do fine
-I will want to replace the rocker arm assembly and go with something a little better, but nothing high dollar
-I will end up having the mains line honed b/c I want to run main studs, and run a new factory style windage tray
-I don't think that a hv oil pump would hurt anything either
-I have a set of Heddman headers #78030 nothing fancy, just something for now
-Do plan on running a 3" exhaust system this way if down the road I run something.. more, then I'll have an exhaust system that should be able to handle it
I'm thinking that's about it, wondering what you all think. I know the gears are numerically low, but until later on, this is what I'll be running. I'm not sure what cam to run, I was looking at Mancini Racing, and saw a cam kit they offer that has an PM range of idle to 5800 rpm, I think it was a Mopar cam, let me see if I can find the kit... Here's the link
http://chucker54.stores.yahoo.net/maravapopa1.html it's part #P4452783. I looked the spec's up for that cam, here's what it says:

Lobe Separation (degrees) 115
Camshaft Gear Attachment 1-bolt
Intake Valve Lash 0.000 in.
Exhaust Valve Lash 0.000 in.
It seems like a small cam, esp for a motor that should be of a performance nature, then again.... From what I understand, the pistons listed above should be fine for my application, hoping to bump the compression up some with those pistons, I'm not planning on running forced induction, and no NOX. This will be just something to run around in, and should I want to show off some, maybe even light the tires up every once in a while. I look forward to your questions and comments, thanks for your time in looking at this and any help you might can lend.
