that carb will be to little
1000HP C460 heads with 4.44 bore
What do you guys think about the proposed combination below? I am aware of all the quirks fitting C heads to the 4.44 bore and know all about better blocks A460/Eliminator but this is being considered for more of a Ford vs. Chevy complete *** whippin. Is 1000 hp possible here N/A? I know A460 heads will work here but I feel the C460's properly ported and setup will still be a better head than all out A's. If I left somthing out, please ask. What do you guys think?.....good, bad and ugly

At first blush I don't see that combo working.
A 2.45" valve on a 4.44" bore will have some serious shrouding going on. How much block grinding are you going to do?
What rpm range are you thinking of ?
1,000hp out of 557" is 1.8 hp/ cu in so it's not a crazy number I just don't think that combo will pull it off. The 1,050 will be to small.

Yes, I know the carb would be too small but it is what we have at the moment and can get Pro Systems to make it do whatever we need. This is a proposed combo that is subject to change anywhere for any reason as we see fit to accomplish the goal. As far as Intake valve shrouding, I can could use a 2.400 instead of the 2.450 to help with unshrouding and hopefully not have to notch anything (only a mock up with my parts and playing with cam lift will determine this). I know this has been done and I have seen it years ago with some early c460 castings which had the valves spread slightly more than the current castings however; I don't remember all the details on the build. That is why I need all the input you guys can give as to what should work as a baseline and can modify as needed from there. As for rpm range, I was thinking 3000 to 7000 ish. Even with reduced valves sizes, C heads should still support 550 inches pretty well.
There is more to HP than pure airflow. Velocity has allot to do with it the head will support 550" no problem, the question is at what rpm?I was thinking 3000 to 7000 ish. Even with reduced valves sizes, C heads should still support 550 inches pretty well.
Do you know flow numbers of the heads ?
FYI, from another thread: The 1,071 hp from 600" is 1.79 hp/cu. in. I don't see your combo pulling that off.

I don't think I would use Eagle rods in a 1000 hp engine. With that 4.5" crank it wouldn't be very long till they knock a hole in something. Use the GRP's or an Oliver steel rod.
We do not have C heads in hand as of yet. We have no trouble getting them and having them set up as needed. I have a brand new virgin set of Ford A460 (TFS head but Ford logo on head) heads but we are trying to possibly accomplish somthing here with the C460's. We have several engines that make very good power with the Blue Thunder B heads and a 514 (4.150*4.44 bore) with Kasse ported A429's that runs better than it should. To me, using the a460's, like I would set them up using titanium valves and shaft rockers, would come close to C460 $$$. A460 heads at this point feels like a side ways movement instead of forward movement. We are in a position where we have the time and can experiment with the C heads. If we need to spin this engine higher to possibly make than kind of power we will. It dosen't mean it will make that power but we can attempt. We will probably use GRP alumnum rods even though have no issue with the Scat and Eagle H beams. By the time I have the eagles upgraded with L19's they become cost prohibitive.

Go down towards the bottom and you'll see a lot of good info on C460's on a 4.44 bore.

This will be alright for a strictly drag engine. You'll have to do seasonal tear-downs, and replace any suspect parts.What do you guys think about the proposed combination below?

IMHO, I believe you can make your goals.
DIVE-AA thick web CJ block fitted with Milodon caps, filled to pump holes, bushed lifter bore
This is good, may not have to bush lifter bores.
Diamond or CP gas ported (13.5-15.0:1 compression) pistons for C460 heads in 4.44 bore
Keep compression to 13.5 to 1.
Vacuum pump used for low tension rings
Just use the low tension rings.
Eagle 6.700-6.800 rods with w/L19 bolts (maybe possible GRP aluminum rods as option)
Steel rods will be fine. You will have to open the clearance at the parting lines alittle with the steel rods. 7000-7500 rpm is going to be required.
4.500 forged steel crankshaft
Good.
New C460 heads 2.45 Int 1.800Ex heads will be ported to whatever we need no skimp here
Use 2.4 and 1.8 Titanium valves. Have a professional, a.k.a. Charlie Evans, ET Performance, or Jon Kaase do the necessary port and set-up work.
Ford C460 single 4bbl intake ported to max
It will not take "ported to max" to achieve your goals.
Custom Ultradyne solid roller (Specs unknown at this time)
Get a custom Comp Cams made from who-ever does the head and intake work.
Pro Systems 1050 carb
As you stated, have Pro Systems build you a custom carb for your application.
Hope that helps,

Thanks Dave!
This will be strickly a purpose built grudge engine. If were lucky, it may see 10-15 per year. We could easily use an A460 or Eliminator block but the factory piece is part of the bait.
Thanks Dave!

do you look at their blocks ? who tells the truth ? your taking a big leap from those e/b A 429 headsThanks Dave!

LOL.the factory piece is part of the bait to the clueless Chevy guys in my area.
Believe me, they ain't going to be looking at your block. They're going to be looking at the large cylinder heads.
That being said, you really should just run a FRPP A460 block. You can still call it a Ford piece, and run a 4.5 bore, 4.3 stroke deal, IMHO. It would make an easier "package".
Hope that helps,
Dave
or a 4.5x4.5 for 572ci would be better for the c-heads imo
Chevy guys ain't gonna know what block you're running anyways! Cause it's NOT A CHEVY!!!
I know it might not sound possible in 2010 but I'm around DIE HARD chevy people that don't really even know about what they run as far a chevy parts. If it's a Ford it dosen't matter what head is on. They wouldn't know the difference from an A429 from a THOR.
A few friends have built small bore C-460 engines, they all left power on the table. I would say 900-950hp is realistic, 1000 hp I don't see happening. Intake valve size was also reduced, I believe 2.400 was what they used.
then there is no reason not to get a A460 or Eliminator block . moneny ? if thats the case better to start with A460 heads and block . rockers for the C head cost almost the same as a - A460 blockI know it might not sound possible in 2010 but I'm around DIE HARD chevy people that don't really even know about what they run as far a chevy parts. If it's a Ford it dosen't matter what head is on. They wouldn't know the difference from an A429 from a THOR.
