that carb will be to little
X2At 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.
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.
Hot Rod Magazine Nov '94: Jon Kaase 600" single carb 1,071 hp, T/R with dual dommies 1,205.
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? 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
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
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.
do you look at their blocks ? who tells the truth ? your taking a big leap from those e/b A 429 headsThanks 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.
Thank you.....GREAT read!http://www.429-460.com/proven-builds-f4/cylinder-head-info-gathered-by-djohagin-t122-15.htm
Go down towards the bottom and you'll see a lot of good info on C460's on a 4.44 bore.
LOL.the factory piece is part of the bait to the clueless Chevy guys in my area.
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.
