Hello, im new to the forum, been reading it for a week or so. Im rather impressed with all the knowlege here. ok, on to the subject. I'm building an 83 mustang gt with a 460 in it. i got a good deal on a 460 with a c6 and a stock brand new converter, 500 bucks. so i said hell, bye bye 302. well.....a few dollars later i have the proper swap/install kit, and a few goodies.

79 460 block
in the process of building ported dove-c heads
no intake yet
holley 750 double pumper
msd-6al(built in rev limiter for my over zealous right foot)
comp cams 280H with lifters and double valvesprings
530 lift intake and exhaust.

i still have to get the re-ring kit for it, finish my heads, get an intake and a few other small details. about 1000 more dollars and the beast will live.

2200 converter sound ok?
timing gears, or timing chain setup? i have both.
forged or hypereutectic pistons
stock shot peened rods, or forged
im just looking for advice

i wanted to know if anybody has any dove-c porting experience. i was wondering what valve sizes are practical. i was thinking of going with a 2.25/1.76 setup, is that too big??

my goals are to beat my buddy's eclipse, which isnt that fast, 350 horses AWD. its fast for an eclipse.....he rapes v8s all the time. i dont want him to even have a chance.

my next goal is to get above the 500 horsepower mark. everybody says 460s dont have that much horsepower, that they are torque monsters. is 500 easily achievable? i would think so based on past experiences...but rumors have me scared.

my last goal (far fetched) is to pick the wheels off the ground on DOT slicks. i know this engine makes monster torque....but my 8.8 rear wont take it ....hell, the car will probably twist in half.

any advice would be greatful. if anybody has a setup even REMOTELY similar, please post so i have something to compare to.

 

I'd suggest you look at some of the Mustang Forums. There are a bunch of them out there and they have vast experience with the 460 in a light weight car. In most cases a 460 build for a heavy truck isn't going to be suitable for your application.

 

what u need is a pair of aluminum cobrajet heads.go with the gears and use a rollercam you wont get beat by you buddy or none of his buddys lol

 

Check out FRPP and look at the specs on their Big block.
What is the rpm range of the cam, I am thinking a 2800 conveter would be better.
Either piston will work. If you are going to use NOS, then definatly forged.
The stock rods should hold up to 6000 rpm as long as they are checked and good.
The CobraJet heads are great, but will throw your $1000 budget out the window. If you are using the D0VE heads, and the stock style rockers, you will need to run the 70 style pushrods. They are different length than the 79's.
Put frame connectors on the car to keep it from twisting. The 8.8 is almost as strong as a 9". Don''t under estimate it.

With that light of a car you will want a higher stall, maybe 2800 as suggested, but probably at least 24-2500. Also, you will definitely want forged pistons. Rods, it depends. What casting numbers? D0OE? Those are the good ones. Should be good to around 6500 with ARP bolts. If it were me, I'd go aluminum heads. More power and not that much more expensive by the time you make stockers good. But if you got them already some serious hp can be made with old iron. I'd also go with a roller cam. Crower has one with "only" about .575 lift. The thing is, it will still idle okay, you'll make some vacuum, yet you get all the benefits of a roller, less friction, steeper ramps, no valve float, etc., etc. In a well tuned 460 with good flowing heads that Crower cam will make about 520-530 hp and over 600 ft.lbs of torque. Yeah, baby!!!

ok guys, so 2800 converter and aluminum heads....thats XPENSIVE. i can get the converter fine. heads are another story. i already have the dove-c's so im gonna spend a LITTLE money on em, just a mild polish and all new guts. still need intake and a few other lil parts. as for the cam, i cant afford to put roller setup into my block, unless theres a cheaper than 500 dollar way to do it(parts included). thanks for all the helpful info.

 

join bigblockfox group on yahoo. Once there you can search the archives, and its an active group with half dozen to a dozen or more posts a day. Lots of knowledge is on that board!

As far as pulling the wheels, you can do that easier with a small block since you aren't starting out with a couple hundred extra pounds over the front.

 

when porting dove heads, place the new intake gasket on the intake side of the head. Using a marker, mark the areas of metal you can see inside the port hole of the gasket. Then using a die grinder carefully cut out the metal untill there are no marks left. Be very careful that you dont touch the valve pocket area. Then using a sanding flap wheel, polish the inside of the port untill it looks like glass. It will flow a hell of a lot better. You can also grind the E.G.R. hump out of the bottom of the exhaust port but dont touch the roof of the exh port cause its very close to a water jacket.Now your flowing

 

In most cases a mirror finish on the exhaust port is desirable, but the intake should be more a of mat finish (not polished) to provide 'tumble' to the intake mixture for an even air/fuel charge.
