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."

Just want to say thanx to everone for the replys, but I am still kind of lost. I think I need to keep the 600cfm carb on for ther first year, will I starve my engine and kill it? My first year of driving will be mild to work out all of the bugs in the truck. If there is no problem with that, I will keep it on for now. I am not an engine guy so the compression and all that stuff does not help me. If I have a compression test done on the engine will this help me in determining if I can use unleaded gas or not? I have a buddy that can do that for me.

I am looking into a new carb but the cost is not in my budget right at this time, besides, I would like it to have the auto choke on it and mine is a manual 600cfm. Any one have a larger carb with an auto choke they wanna trade?

Just let me know , any help is good help!

thanx, John

I was reading this link on another forum. This guy is using the same carb as you. Also talks about d3ve heads.

I have never heard about riuning your engine with an underpower carb. Alot of people went to smaller carbs during the 70's gas crisis! As for the unleaded vs. leaded issue, some of the guys with more experience will have to answer! My engine is a 71, and is running on unleaded! Steve.

Steve......I dont know what I would do without you. Too bad your not a chick, but my wife would not like that. I just have to say you have helped me a ton. I have read a lot of threads and most of all, the ones you have sent me. I am pretty confident that I will not KILL the 460 with the 600cfm carb now with your help. I am working on looking for the edelbrock Thunder 800cfm carb #1813-(4)<--the shiney one, at a good price but I will probably do the start up with the 600cfm. I hope I will find a new carb at our swap meets this spring Like in Jefferson WI but I still have to wire the whole truck, build a custom fule tank and finish the floor and exhaust.

oh Steve, do you have a fuel tank for your truck?
I have a BRAND NEW Rock Valley stainless steel fuel tank that may work for your truck. I believe it will work for your 1948 but it was built for my 1947. The tank is located on the driver side inbetween the frame rails and I even have the original mounts for the tank and the straps.

I am going to build a custom tank in the back and fill behind the plate. My truck is too low to the ground to run the dual exhaust around the tank cause it takes up the whole area, I believe it is a 16 or 18 gallon tank. If you are interested I can send you some pictures and a price,,,,,,cheep! I am located in Wisconsin. If you are even slightly interested I can hold off but I was going to put it on ebay next month.
And again...thanx everyone!
John

Here's ashot of the my current setup that camee with the truck. It is one of the issues I have to tackle as well. Yeah I'd love to see some shots and may be interested if I can fit it in the back. Not the best pic, but you get the drift.

How much did you want for the gas tank?
