Hey All
My name on here is ShaZam,Some of you may know me already as the guy with the 800 H.p. Bored and Stroked 400..

Well I'm now going to build me a 460 and I'm looking to make at least a 1100 H.P. with it.Here's what I got so far sitting in the shop on the shelve.

On the engine stand Just back from machine shop. D1VE block bored and hone to 4.390, zero decked, align honed, new cam bearings/freeze plugs. Eagle 4.14 nodular crank, Eagle H beam 3D 6.800 rods, and JE SRP flat top pistons. This will give me 501 cubic inches and about 12.5:1 with early closed chambered heads.Which I have on the shelve also, but upgraded too these.

A Set of BLUE THUNDER B PORT ALUMINUM HEADS That have the raised B Port for better flow. Heads have been PORTED & POLISHED for increased FLOW and HORSE POWER. They have 85 CC Chambers and uses 2.300 & 1.880 Valves.

460 port o sonic cobra jet intake that has been professionally ported buy Roush.

Now I'm looking for a good Roller cam for this combo.


Any 460 Hotrodders out there that care to share...

Is it a DIVE-AA block with 4-bolt mains?

 

No just a 2 bolt mains.. plan to use a main stud girdle to help stiffen the lower end ..

 

Over 8-900hp with a 2-bolt, stud girdle, water jacket filler or not, will cause things to move around that you don't want moving around. There are a couple of 4-bolt conversions for the thin-webbed DIVEs. An SVO 4-bolt block with thick webs would be far better for your application.

I don't play in that league, but the people who do generally use tunnel ram manifolds, often fabricated, to achieve those hp levels.

 

I thought someone posted that the D1VE had the thicker main bearing webs already? Did I miss something?

Ford started it; Ford will finish it!

 

There is a web site link on my gallery page for the info you need. Lots of experts there willing to share their experience and advice. You will not be driving this on the street I assume!

I personaly don't think you can do it normaly aspriated with out spending a ton of money....upwards of $30,000 plus...your talking a Pro Stock style of engine here. The easiest way of reaching a 1,100 HP level would be to run a 10-71 blower with alcohol injection, you would still need the best in bottom end parts (SVO block, forged crank, aluminum rods, roller cam) as well as a Pro-Stock style of head. Deen

 

Only DIVE-AA had the thick webs. DIVE with other codes are thin-webbed and the most common block from '71-78.

NO Mike this is a purpose built motor for my Pulling truck .. It will never see the open road... Well Maybe never ....


And I can't use a blower .. only One carb. allowed but I can run Alcohol...

 

I have the same "B" design heads you have with the same intake valve size. The exhaust is only a 1.8" because I was told by the shop that the valves would hit each other in their stock location. When I first got the heads done, the valves hit each other with 2.25 and 1.88. I had them turned to 2.23 and 1.85. Now I have 2.300 and 1.8 and they flow 345@.800" int, and 260@.800" exh. The ports have been cleaned up and lightly ported. Compression ratio is 14.5:1. I have a Comp roller with .727" int/.692" exh, 276/280 duration at .050". It has a tunnel ram with 2 750 holleys. I have never had it dynoed, but the 6.13@112 it runs in the 1/8 mile equals to around 700hp in a 2900 lb truck. I know a guy with a 650" motor in a pulling truck with 17.5:1 comp ratio on alcohol with the "A" motorsport heads making 1200 hp. If you want an exact list of my combo with pics of my cam card and flow specs e-mail me. I would like more power out of mine, too.

 

My BT's flow that well with a Ford exhaust, flow isn't everything. You'll never even get close to a thousand with that dinosaur intake. 1100 is a big number with a single four & no power adders.

 

Qtrmiler,
Does the BT "A" head flow that out of the box or does it require some porting? I bought the "B" design head because it was easier to buy header kits for BBC style ports. I had to build the headers for the truck because of the tube frame. Anyway, you are right. Flow isn't everything. I was told my heads flowed enough for my engine at 466 cid. They said that only if I went up to a 557 cid motor would the heads need more work. I heard that the lower lift flows were important, too. I increased my flows at .300, .400, and .500 lift on the exh by 18% with a different valve job and chamber work. The int responded also, but not as well. It improved about 10% at the same lifts. It has taken years for my friend with the 650 to go over 1000 hp. He has spent a lot of time on the dyno working with the fuel system to get most of his improvements. I do know that he had injectors in the int manifold as well as the head itself. It had a 5-stage dry sump on it also. Anyway, just my .02. Wished I had 1000hp!! I could really show those chevy guys then! That would be a handful to drive , though.

 

Once you reach the level of high-end aftermarket block, crank, rods, pistons, heads, manifolds, induction and ignition, there's very little difference in the performance potential of a BB Ford or Chevy. The winners are the ones who pay attention to ALL the details and achieve consistancy.

 

A quick "rule of thumb" You can get 2 horse per cfm of air flow.
So normally aspirated you will need close to 500CFM of air flow to hit 1000HP.

TMI, where did you get this information? On my 514 it took a 1050 Dominator, large roller cam and over 7000 RPM to make 725-750 HP. On my small block Corvette with a small blower and 750 Holley I'm only making 500 HP (730 HP with Nitrous)...am I missing something here?
