1) IS THERE ANY WAY TO TELL WHICH FUEL TO RUN FROM THE CAST NUMBERS ON THE HEAD OR AT LEAST AROUND WHAT YEAR THE MOTOR WAS ASSEMBLED?

2) I READ SOMEWHERE THAT THE 460 HAD A THERMOSTAT HOUSING THAT WAS STRAIGHT UP AND THAT IS HOW YOU CAN TELL THE MOTOR FROM A 429. MINE IS AT A 90* BUT IS AN AFTERMARKET HOUSING. ARE THESE UNIVERSAL?

3) THE ORIGINAL OWNER PUT AN EDLEBROCK PERFORMER INTAKE MANIFOLD ON THE 460 BUT THIS IS WHERE IT GETS STRANGE. HE PUT AN EDLEBROCK 1405 600CFM CARB ON IT. WILL THIS STARVE MY ENGINE? I AM NOT LOOKIN TO RACE WITH THIS TRUCK,A LITTLE TIRE SMOKE EVERY ONCE IN A WHILE WOULD BE NICE, BUT WANT IT TO BE A GOOD CRUISER AT THE SAME TIME. EDLEBROCK RECOMMENDS A 750CFM FOR THE 460. WILL I KILL MY ENGINE IF I RUN THE 600CFM CARB?

On the heads----------D3VE A2A

Hope this helps.....

John,

I don't know of any factory Ford crate motors that came with D3VE heads, short of the marine applicable 460's that Ford offered in the 1970's-1980's. There are plenty of rebuilder 460 motors out there other than Ford crate motors, though.

D3VE heads are typically 96-97cc's in the combustion chamber and with flat top pistons, c/r is usually around 9.25:1. However, no rebuilders that I know of use flat tops because of todays low octane fuel. Usually, the standard rebuilder piston used is a 24cc dished piston that puts c/r at a dismal 8:1 with the D3VE heads.

I think the engine would produce greater power with a larger carburetor than the Eldelbrock 600. In 1974, the 460 came with an Edelbrock (Carter, bought by Edelbrock) carb that was 800 (or so) cfm. The Edelbrock carb will allow decent fuel economy and run well; a Holley 750 (or even 850) will make a lot more power than the Edelbrock and have better tunability, but it will provide less fuel mileage. Personally, I would replace the current carb with a Holley if you want the "tire smokey."
