Opinions/Advice Wanted 460 Ford mods

[HotHallet]

I have a 460 Ford in my 19 Hallett with an Isky 280 Mega Hydraulic flat tappet camshaft, 10 qt. pan, and pretty much stock internals. Had it apart a year ago and everything looked fine internally. I have a set of Edelbrock aluminum heads and a Weiand tunnel ram with two 450's( I know the carbs are probably too small)ready to go on. Do I need to spend some money on beefing up the bottom end or just run it. I thought about changing the cam to a roller set up and switching the carbs to 650's. I need advice! Don't want to spin that motor to hard with stock internals and I know that will not change until the pump work is done. Boat has a 12JC Berk with A impeller and manual diverter, Boat runs great now up to about 4,600 but I am looking for just a little more top end. Some have suggested switching the rockers and adding ARP rod bolts and going with it. I need to GPS the boat again but figure it goes about 61-62 MPH. Would like to 65-67.

Senor Hallet,
If all you are looking for is 67mph, you're not going to need that much more RPM and I'd say the most you have to do to the bottom end (asside from a clearance check etc) is the ARP bolts in the rods. Honestly with the parts you have in hand, you should be setting your goals a little higher :) Think about how fast you ultimately want to go. Once you hit 67, you'll want 70, then 75, so on and so forth. Figure out how fast you want to go compared to how much you want to spend, and then build to be reliable at the best compromise for the speed and price. It doesn't make sense to spend money to build it again for 67mph if you know you're going to want 75mph down the road. Pay once, cry once. BTW, I know this guy running a nice 460 stroker combo that you can probably get some ideas off of. :)

Hey HH,
I have a 460 also and dont know much about them. I started a thread on "gear heads" I am getting a ton of info. check it out. The thread is "super cobra jet heads" Or somthin like that.

I have a 460 Ford in my 19 Hallett with an Isky 280 Mega Hydraulic flat tappet camshaft, 10 qt. pan, and pretty much stock internals.HotHallet, I have the same camshaft, an Isky 280 Mega cam. There are two profiles: .565/232@.050"/110* & .565/232@.050"/108* Which one do you have?
[b]I have a set of Edelbrock aluminum heads and a Weiand tunnel ram with two 450's( I know the carbs are probably too small)ready to go on. While the carbs will run, they are too small for the 460. I am running two 660's with the same cam, and if I wanted, could probably run two 750's.
[b]Do I need to spend some money on beefing up the bottom end or just run it. I thought about changing the cam to a roller set up and switching the carbs to 650's. You have a few options for motor set-up with the components you have. If your engine is together and running now, then just run it. Mine originally had passenger car rods too, but with Milodon bolts. It went to 4800 rpm all day long. Considering the way you want to set your motor up, just do the bolt-on stuff now (T/R w/450's) and when it's time to rebuild your shortblock, you can get the right pistons for those heads and better rods/bolts too.
[b]I...don't want to spin that motor too hard with stock internals (and I know I will not change them until the pump work is done. Boat has a 12JC Berk with A impeller and manual diverter, Boat runs great now up to about 4,600 but I am looking for just a little more top end.To acheive the speed you wish--and possibly faster--you can do it with your current cam. My boat goes 80 mph with that cam.
I think your stock rods and bolts are good to 5000 rpm. Jet boat motors are subject to a lot of load when your floor it and if you want to go run more than 5000 rpm sustained, then you should get nice aftermarket rod bolts, preferably better rods too.
[b]Some have suggested switching the rockers and adding ARP rod bolts and going with it. I need to GPS the boat again but figure it goes about 61-62 MPH. Would like to 65-67. Roller rockers for those sustained rpm's would be nice.
This possibility of a roller cam, though, points you in the direction of a whole different motor....

Thanks for all the info! I am still debating.

go roller and never look back. :cool: BTW I spin my ford 5300rpm on the stock rod bolts(footballs) and 2 bolt main(stock bolts). been doing it for 4 years now. but then again I only have one carb. wink those BBF are tougher than you think.

go for the 4.5 inch stroked crankshaft. entire kit including crank, rods, pitons, rings and bearings for $1600. i just finished one in a new tx-19 hull and its not dialed yet but is turning a double A impellor 5200-5400 rpm with mild cam. mild mannered low maintenance moter.

okiedave, WERE DID OU GET THAT KIT??

Omega I gots ta say.....I've been hearing so much favorable testimony about the strength of factory Ford rods that I am beginning to believe I have been much too conservative in my estimations about their strength in this application.
Great news.

Ive got a similar kit, 514 inches made by eagle. I paid a little over $1400.00 for it balanced but that was a little over a year ago

[Hallett19]

work on the hull or the pump, set the pump back, take the hook out of the hull, that should help and be more effiecient then pulling the motor apart and tossing hotrod pieces in.

maybe you should pull the motor out and do some of the aforementioned upgrades ....... thanks alot LO ..... sniff, sniff, is that sarcasm I smell ??? :D
Here is my rundown on my 460 in a 19 Hallett MC (heavy boat) :
Berk 12JA A imp.
BBF 460: from the bottom up
dooley 10 qt pan w/ rear pickup and baffles
MAC windage tray
motorsport oil pump
all stock crank/rods/pistons
motorsport timing chain set at 0 degrees
Isky A impeller jet boat cam
decked block
double valve springs in A3A heads (shitty heads)
Hollman Moody logs
Weiand Stealth intake
TPC Holley 780 (bad ass carb!!!)
I turn almost 4800 rpms at around 58 GPS'd loaded down, up stream in havasu w/ NO tuning. I'm sure with some carb tuning dry boat, flat water, I could get 62+. I'm not worried about speed though, I just like a boat that runs all the time, which mine isnt ...... burningm :mad: cry yuk you get the idea.......

mustang depot sells stroker kits for fords. so does coast high perf. i put a 427 windsor stroker in my cobra kit car and it is awesome.
the 565 ci in my new boat is the biggest i have done so far. i have run 521's for many years with roller valve trains, alcohal injection, dual carbs, nitrous, lots of combinations. i am after low maint. now and have a mild hyd. cam and the torque goes well with the big impellor.

[XClutchboy725]

HotHallet, Here's what you need to do...
Promote the Ford Motor to BOAT ANCHOR and put a Chevy in! :D
(That should piss off the Ford guys!)

When you say that you have "A3A" heads, do you mean D3VE-A2A's? They are not bad heads as originally thought by Ford enthusiasts. Times change, and technical "know-how" always advances. And so now people have discovered just how to tweak the D3VE-A2A heads and make them perform excellently--almost on par with D0VE's (seriously--D3VE "smogger heads" can now be exhaust-ported to 200cfm@.600" vs 230cfm@.600" for D0VE's). This has opened up a whole new group of stock Ford heads that can be made to perform, and for a cheap price because there are so damn many of these heads out there.

I had a 19ft hallet with a very mild 468 chevy and at ran low 10s at 80mph.what hull do you have? :rolleyes:

Hallet...I publicly apologize for my response; it was indeed much too smart-ass a reply.LO Why are you appologizing ?? I thought it was funny. Its all in good humor lakes, no offense taken.Thats my kind of dry humor, sarcasm at its finest, here comes 5 stars down your alley :cool:
And yeah, you are right about my heads, D3VE-A2A, whats the deal with them now ? not bad heads ? any dimentions or good upgrade advice ? anyone can jump in on this one.
SVTRich, my hull is an MC18, but measures closer to 20 feet. Its not a bubble deck, its a closed bow, 7 seater with a covered engine, ski locker, swim step, kind of an old man boat, but great for what I use it for, partying, stereo, neon night cruises and wakeboarding, wana see ? :D http://www.***boat.com/image_center/data/500/128DCP01587-med.JPG

from what i have read, the D3VE-A2A's have very restrictive exhaust ports (due to smog stuff). However, with alittle porting, you can fix that. it doesnt seem too terribly difficult, i plan on doing mine myself over the winter with a dremel. The main thing to do it grind out all the humps in the exhaust ports.

LO I am one who played with the NOS on my bbf and the internals were stock.I spun the motor to 5600 many times before pump work then it dropped to 5300.Did this for one season but have hit 4800-5k many times for more than a few seconds NEVER broke an internal part.As for valve train well i learned what guide plates,BBC rockers-studs,hardened push rods are for.They are solid internals for sure

[Snorider]

Yesterday, i got caught out in a lightning storm, and was 7 miles from my trailer... Well, i held it at WOT until i got to the trailer, spinning 4800rpm for 7 minutes nonstop.
Once i finally got there, i still had decent oil pressure (25lbs @ idle, 55@wot), but i know i had to pump the pan dry while doing it (its only a 5-6qt pan).
Still, its good to know that my stock rods held up fine.... Especially since a few times i caught a wave and launched the boat, which let the tach sweep into the 6k region till the boat settled back down. :D
Oh yea, it was a stock 460 BBF :p
