Ultimate EFI Build (Re-Post)
I am submitting this post to give thanks to this web site which has helped to contrubute to a successful engine build.
My truck is a 97 F-250HD, 4x4, long bed, extended cab, w/E40D automatic trans, with 167,000 trouble free miles, other than a leaking rear main oil seal.
Like many of you I was looking for more power out of my 460, so I decided to do a major rebuild and install some aftermarket components to provide additional power, while utilizing the stock EFI system so I can pass our lovely California smog test.
I an delighted to say that this build met my expectations. The following is a list of the aftermarket components that were installed during the engine build process.
a. Comp Cams #34-255-5 EFI performance cam, with new valves, springs and lifters.
b. Pocket port cylinder heads.
c. Doug Thorley "Try-Y" headers, #THY-214Y-F16-C
d. 3" Bullett performance mufflet and exhaust pipe.
e. BBK Twin Throttle Body, Summit #BBK-3502
f. BBK Adjustable Fuel Pressure Regulator (set @ 41 PSI), Summit #BBK- 1707.
g. BBK Fuel Regulator Gauge, Summit # BBK-1617
h. new 4-row (all metal) radiator, Summit #PLI-436009
i. Heavy duty torque converter from Midwest Converters, #F59-1BRY
j. Banks Trans Command, electronic transmission control module.
k. Timing advanced to 12 degrees BTDC
In addition to the above aftermarket parts, I also installed new pistons, 0.030 over.
Although I do not have any documented Dyno results to share with you, I can truthfully say that the increased power is a noticable improvement, especially at 1/2 throttle. I can now haul heavy loads and tow my Jeep over steep mountian passess in 3rd gear without the need to go to 2nd gear, full throttle. My milage under normal, unloaded conditions has risen from the previous 10 MPG to now 12 MPG.
If you want a dependable engine, utilizing the stock EFI system, this build should be just the thing for you.

Hi guys, hope some one can help. Trying to put together a new 460 for my old 1986 350 4 door dually, gas. The old block had 5 cracked pistons and a striped head bolt. I am not having good luck finding a good short block, for a gas engine. I just picked up what was a early D9TE-AB truck short block, was told it cane from a tow truck with a gas engine??? When i looked at the pistons they didn't look wright, now i am sure this engine is EFI !!!Was wondering if any one has used EFI block with early D3VE-A2A heads summit SUM-3501 cam hyd lift, int. 503 ext. 503 duration 276/286. Aluminum intake holley 650 cfm carb. Do i have to start looking for a gas short block, or can this EFI block work? Will the valves hit the pistons?? Will the compression be to high, and require hi test gas ?? THANKS IN ADVANCE RICK.

How much do headers really add to a stock 460 EFI?
According to this Four Wheeler article, it's 11 hp...

If my manifolds aren't leaking, I'm not sure it's worth risking breaking studs for 11 hp.

Thanks. I got it on last weekend. Took about 20 minutes and was a piece of cake. Only thing I had to do was borrow an o ring off the original regulator. I also put on the bbk gauge and have it set at ~41 pounds. Since I was taking off the air tubes anyway, I went ahead and cut out those goofy factory air horns. Yeah. Should have done hat 2 years ago if I would have known They were in there!! Complete woke up truck. I have WAY more gear in all 5 speeds as it's able to breathe. Happy with it all in all.
Lots of helpful info on this site. I appreciate everyone's input. Thinking about doing the rhp intake next!!

I have a 1997 Ford F250 HD 460 4x2 and have a similar setup. I have everything but the fuel pressure regulator. It was like looking at my engine specs. I have my timing set to 17 btdc and seems to be just fine. Tons of power. I am going to do the pressure regulator to finish it off. Thanks for the writeup.
