Hello again everyone! As most of all of you know I have a 1968 Mercury Montego MX Station Wagon with a 429 C6 8" Rear. The rear is getting changed out with a 9" with a 3.25 ratio. Well now after a year I have beat that 429 up pretty bad as it was already a used engine and what not. Recently I have been gathering parts to build a new 460 for it. I'm in the process of tearing it down and then it will be off to the machine shop! This is my first build besides just replacing random parts. I will list the things I have and then the things I still need. Have a few questions as well, anyway...

Parts I have:

1) C9VE 460 short block, stock standard bore
2) Set of TRW Forged Domed pistons PN 516-99 Standard bore
3) Set of Pro Comp aluminum heads - Bare, plan to port exhaust

All other parts will be used off my current 429 in the wagon. Parts I plan to reuse:
1) Holley 750 duel feed vac sec
2) Melling HV oil pump
3) Exhaust manifolds late 70's truck, will these work with pro comps"

So basically a high compression aluminum headed 460 engine. It's going in a wagon that weighs about 36-3700. I am running a stock stall beefed up c6 with a trans go stage 2 shift kit. Will have a 9" rear with 3.25 gears, but will eventually up grade to 3.50 posi or so. I have an edelbrock performer but I might switch to a stealth or something else, still up for debate. I would like a mean 500+ hp&tq combo for my wagon. I have never had a 500hp car but i hear its pretty easy with a 460 and still have street manners. I don't care if its alittle choppy but I would like plenty of low end torque. I have read builds where they have acheived this under 6500. I want to keep using a stock stall because most streets around here are 25 mph. Will occasionally take to the track but basically driving around town. Now onto things I need:

1) Cam
2) Carb
3) Intake, what would be best a performer, a stealth,etc?
4) Valves, guides, studs, springs, etc for the Pro Comp heads
5) Roller rockers
6) Gaskets

So questions I have are:

1) Whats my compression with domed pistons and Pro Comps with a c9ve block?
2) What hardware and valves should I get for the Pro Comp? Should I just have the engine shop get all the stuff for them or can I get them from a vendor?
3) What head gasket should I use?
4) Can I use my exhaust manifolds with my Pro Comps?
5) Cam? think I'll get one from a vendor, how big will I need it?
6) How much lift can the Pro Comps handle?
7) I need rings and wrist pin locks for the TRW's, where do I get those?

I'm sure I'll think of something else later but for now that's about it. Let know if you need more details, think I was pretty informative.

HELP ME GO FAST!!!!!!!:D

Im in the same "boat" im curious as to how your build goes. Mine is a 69 Continental road car. gotta stay a driver with a close to stock converter. and the intake is my sticking point what will fit under the stock hood.

I would cc the heads so you know what they are for sure. (They vary from what I have seen)
Let the machine shop get the valves for them and set them up with your cam specs.
If this will be a N/A combo a good fel pro will work.
Not sure on exhaust but will prolly work.
Give a vendor a call they can help on the cam and lift you will need for the pro comps they can also get you rings and locks for the pistons.

Hope this helps - mike

Edit: once the heads are cc'd you can get the comp..

Yes I plan to get to get a cam from a vendor. Taking it to the machine shop shortly to get everything checked out. They said they could get rings and locks and what not. I wish that Carl, Scotty, Randy, etc were closer to me but oh well. Im excited to get this thing in motion. I've never had a brand new rebuilt engine, always had leaking old P.O.S.'s! Is there anything I should know to tell them at the machine shop clearance wise, etc? I dont if they have done a big block ford before...

I always say if its loose you know it if its tight everybody knows it.

If you are using a stock crank have them check it also you can order bearings in + or - .001 if it is to loose or to tight but most of what I have run into with stock cranks is it will be just fine on clearances with your bearings. As for the pistons cause they are used I would check them also and have each bore done to each piston and tell them to mark the pistons for you so you know what hole the where cut too...

Edit: I like a file to fit ring my self and they can also do that if you don't have the tools to do so.

Yeah I prefer not to have to do any of that because I have never done it before. My block has nice bores and still has cross hatching, think I just can get it honed but we will see. As far as exhaust goes, can I get 500 hp with manifolds? I have 2 1/2" exhaust that goes into full 2" exhaust, should I go with a full 2 1/2" or 3"?

I don't think the manifolds will support that HP they are mighty restrictive. Somebody might chime in and let you know for sure. Happy building and good luck - mike

Yes they are but I dont know pin height or anything. Never figured out conpression before. I know it should be mid to high tens. Found out I have to run cj port exhaust so I need headers. If anyone has a used set that would be sweet otherwise ill keep scouring craigslist and egay.

Yes, but Ryan that would mean that you would have to upgrade your fuel delivery system and carb for the E85. For 500hp, that is not necessary.

I agree it is not needed, I was just asking...

Will my stock rods work with these pistons? Are they too heavy for them? Cleaned them up and found the part number TRW L2443N on them. Should I get ARP rod bolts, or will factory bolts be fine?
