WOW both of you are very knowledgeable when it comes to rebuilding.. i completely understand everything ,, and i will be printing this out and taking it to school to review.. i am very thankful and again i will post pics once everything is in order ,, i will also RESPOND to this thread though out the REBUILD ... thxs guys
very helpful

subscribe to Boports thread about his 460 head porting on this forum...he had some impressive gains on an otherwise stock motor. He mentioned he would be more than happy to send the specs to anyone trying to replicate the port job.

Since you're planning on doing a stock rebuild on a budget, keep an eye on 460ford.com, and craigslist for good parts. Occasionally you'll find 429 heads for a steal, which can provide a good HP boost.

If I were you, in a big heavy truck that was going to be an all purpose build I'd keep the stock, small valve heads though. The smaller valve will improve air intake velocity, which is important to building torque at a usable range. Look at having your heads and block 0-decked. Not only will it ensure a good head to block seal, it'll give you slightly more compression without having to go to a high-dollar, high compression forged piston.

consider doing a good port-matching job on the heads, intake, and exhaust manifolds. Horsepower, the tv show on spike/speed, had a good episode on building a budget 460. Trucks tv show also did a show some time ago where they put a 460 into a bronco, and showed the tips and tricks they used for the rebuild. The shorty headers you mentioned sound like a good plan for building good low end torque, and will free you up substantially on the top end. Both TV shows used to be available for viewing for free on spike.com, and if not you can buy them through the iTunes webpage for like 1.99 each. Its well worth it, IMHO.

When you go to look for cams, consider going with a mild roller cam instead of the lopey sounding flat tappet. A roller cam opens and closes the valve faster and gains more lift, which will improve intake velocity (going back to torque gains), and can do that without having an overly long duration or overlap. The overlap is what gives lopey cams their distincive idle, but it hurts torque down low in the RPM range, which is where you want it in a truck. A roller cam is gonna cost you more upfront, but will give a much better, smoother power delivery than a flat tappet cam, which will let you get more power out without having to abandon your current injection system. Again, looking at a used piece may save you some money, as the lifters are the biggest investment for a roller cam setup. a lot of drag racers using the 460 will swap out parts regularly. Since you won't be winding your big block up to 6000 rpms, its less of an issue with you. shop around while you have the time.

Finally, don't underestimate the value of a balanced drivetrain. A balanced rotating assembly is going to make the engine idle smoother, and will prolong the life of the engine components. A good machine shop will balance your crank for you with your rods and pistons. If you're taking the class on rebuilding, ask your instructor to go into the cost, time, and benefits of doing rod balancing also. In that case you balance all the rods to the same weight, and make sure that the big ends and small ends (crank and piston side) of the rods all weight the same also. If everything is balanced it will help the engine turn smoother, and waste less horsepower.

Finally, I like the 10qt oil pan (I'm guessing you're looking at the one at broncograveyard.com?), but I like it because I was planning on running a bypass oil filtration system on my truck to increase intervals between oil changes. If you're just looking to use it for the extra capacity consider that you'll be paying an extra 20+ dollars at every oil change just for that extra capacity. The extra oil can help decrease operating temps, but that shouldn't be a problem on your application. A good 6 qt pan will probably save you $150+, and thats money you can put into other areas of your truck.

 

Wow amazing info so far thxs copied and printed

 

Man!!! this engine sounds great!! Keep us posted as you go along
