Well, I am starting over here the old one was getting kind of strung out. On a balanced 460 with d3ve heads with 2.19" intake valves, 1.710" exhaust valves, comp 1.7 ratio roller rockers, a .030 line bored block, and some seriously ported out heads, and pn 924-16 valve springs, a performer rpm intake, 1407 carb, guide plates, and pn 7651-16 pushrod set what pistons and cam would be good combination to get to a 500 horsepower or more figure at 6000 ft above sea level?

 

Just get a stroker kit, It will have the pistons with it.

 

Ok where do I find one and what is a good choice, like a 514 or something? what rods do I need? Why can't I use the 460 crank? Reason I ask is I already have a lot of $$$ in it with grinding it, balancing it, and so on.

 

Lots of companies make them, just do a Google search. Find a kit that will suit your needs. Your engine builder should have insisted you stroke it because he knew what you wanted. I wouldn't bother with a 514, go bigger & get a kit that is already balanced.

 

what is the intended use of the engine? if it is for street only, i wouldn't go much bigger cubic inch wise than stock.

 

Before you spend your time, review these threads, where all the info you need to get a 460 right has already been provided or linked to.

I'm not sure what the OP is looking for, but it does not seem to be how to make his 460 run.

 

Good deal. I would like to stay cost conservative this time. The last build cost a lot for what I ended up with, but if I can reuse the same heads, crank and rods then I can do a build for the cost of a balance, a set of pistons and rings, gaskets, and cam. I think I will have to do valvesprings, too. I would work on this build, but I hate to waste any more time and money since it is never going to be what I want since it has stocker pistons and the wrong cam. I think I want atleast 400 hp. I guess 500 is a little out of reach at my altitude with what I have to work with. The truck is a 1978 f-250 4x4. It is a 4 wheeling truck, hunting truck, farm truck, and if I get a good engine built up it will definitely see a few mud runs. I have a performer rpm intake and I will get some good headers. The guy that did the exhaust did kind of a bad job and it leaks a lot, so that will need redone anyway for the headers. I will keep looking around for more advice on the build. I drove the truck a few hundred miles yesterday and it seems to be running fine other than a mysterious coolant leak I can't spot and an oil leak out of the oil cooler line. I think the front of the tranny or the rear main are leaking down the back of the engine, The oil doesn't have much odor that I can smell so I think it is the rear main, so there is another problem that the builder left for me to correct. Is there a place I can find in writing that those h582p pistons are not high compression with a d3 head that I can take to the machinist?
