Pulled my motor today and am planning a build for this winter. Looking for around 500hp
Stock 460 currently, planning on new intake/carb setup and OT headers.
Looking for recommendations on a build to attain the 500hp goal.
I have the D3VE heads so am thinking I might need to go to a different head maybe?
Any suggestions on internals? C/R? Can I get away with stock crank and rods?

YES...im looking for a combo too ;D

C'mon Chromey, you know the drill. Call Lakes Only or JBP. And if that don't work out for you, it isn't to late to put yourself together a nice Olds. ;D

So I have been reading alot on here and am still wondering is the the d0ve head the more desirable head over the d3ve head because of it's ability to change to a roller rocker assembly?
Because my neighbor has a 71 lincoln with a 460 sitting in his yard he said I could have ;D

Here's the site you need to visit for any 460 build info. These guys helped me with my last build.
They live and breath the 460 ford. Look around the site, there is a recipe page for different HP builds.
Paul Kane is there too. He's a jet boater that helped me with pistons and cam.

hey cutter.....my last cruiser with the olds went faster than my 460 cruiser :banghead:...but we are going to be changing that this winter... :o

I added a profile on the 460ford website and started asking questions, so I will keep you all posted on the build if I have any questions!

500 hp with ported D3VE heads is possible. Doing this with pump gas is more involved. Early-style heads (a la D0VE, etc) makes this goal a little easier.
The crankshaft is certainly more than adequate for 500 hp. As far as the connecting rods, I've heard of them letting go at 4400 rpm while at part-throttle cruise and I've also heard of them surviving 8100 rpm in a mid truck....meaning, you never know. If I were building a 500 hp engine and using OEM rods, I'd prep them well (smoothed beams, new rod bolts, etc).
All that being said: pulling 500 hp for a jet boat from an OEM shortblock with dished pistons is not the most wise way to get 500 hp from a Ford (even if it is possible). This is because the 1973-up 460's came with dismal compression ratio, poor upper rpm exhaust flow, poor spark advance, and smallish carburetors. Take care of these things and the engine can be transormed very significantly. Good thing you are going through the entire engine because with careful planning 500 hp can not only be easy to attain with a lot of OEM parts but the same general long block can generate a lot more with simple cam and induction changes.
If you want to just do a top end deal (ported D0VE head swap plus induction, headers, distibutor work, and a timing chain) you can get to 500 hp in many cases, but since you have the engine out and are rebuilding...
