I found an 806 ci stroker kit at flatland racing, and it says to use an svo block. Which got me to thinking, as Ive been looking at a new stroker for my mud toy. So where do i find a tall deck svo block, as I'm sure thats what would be required. Also what cam, heads, intake, carb and header set up would an engine that large need? I'm thinking 12.5:1 compression race fuel motor with through the hood pulling headers. So what do you guys say, what heads should I be trying to find, which block, what duration @.50 and lift cam? Dual quad intake running some big cfm dominator's or something else? And how big should the primary and collectors be on the headers. Thank guys and heres a link to the stroker kit.

Well you need to call C&C Motorsports & order a 5" bore space Roberts design aluminum block with a 12" deck height & a pair of 5" bore space Roberts design hemi heads. As far as cams go, most of the 800+ cubic inch engines are running upwards of 1.25" lift cams. I don't have a clue to duration. So the block will set you back $6575 & the raw head castings are $6500.Anyway what I am getting at is that you can't put a crank that big in an SVO A460 block. THe A460 block has a 10.322" deck height. You would have to put deck spacers to get the height required. About the biggest stroke anybody puts in an A460 block is 4.75". :D

First thing you're going to need is big fat wallet. The block you are looking for is an aluminum 4.9 bore space 12 inch deck block that goes for about $7500, time you get it ready for use. The heads whether you use wedge heads or Hemi heads will be atleast $ 10,000, time you get them hogged out to feed that beast! The rotating assembly you priced would be the cheapest part of the build so far, and when you examined those parts, they would upgrading, that is NOT in original price range. It would way cheaper for you to buy a used big motor than try to build one. You can get a used 815 cu in Ford motor with old style Hemi heads for $30,000 or less. Happy Hunting!

Ok forgive my not knowing. Why does it claim you can use an svo block? Theres no way in hell I can drop fifteen grand on a toy, I had figured in the mid teens, 15-17 thousand for a turn key, turns out I was way off. Oh well, one can dream, right?

I don't mean to depress you, but you are going to have $10,000 to $15,000 in the heads alone if you get a set of heads that an engine that size needs. On an engine like this, estimate your price of things and then multiply that by 3. That should get you close. If you can't find used parts and want to go with the 5" bore space stuff I would say you will be spending $40,000 to $50,000 on parts alone.

Purecountry,

It may seem that the guys are jumping on your case about the 806 CID engine. IMO, they are really jumping on Flatlander Racing's case, because;

1. They have no idea about big block Fords, what you can and can't do, what should or should not be done in a good performance build.
2. They are an internet sales company, (and there are others like them).
3. They are lying in their advertising.
4. It is obvious they have never actually built one of these big 806 CID engines themselves.
5. They (Flatlander Racing) do NOT support this forum, they have never been on here answering questions, or providing help.
6. They (Flatlander Racing) do NOT sponsor any of the events we have put together, i.e., the Ford Bash and the Tech Seminars.

So my suggestion to you (Purecountry), is that you continue to read and learn about BB Fords here on this forum, not some clueless internet sales company trying to take your money. Use the search engine, and also read the FAQ sections.

Hope this helps,

Thank you very much. Ive been working on cars, and trucks for years, but I'm just now getting the money to play with toys. I just got lured in by thoughts of big cubes and big power for a decent price. Oh well live and learn. What would be a good budget stoker motor, that will still make 650 to 700 hp? What stroker kit, block heads, intake and cam combo should I be looking for?

The are probly meaning an alum SVO block. But it theoretically could be done with a cast iron SVO block [A-460] with deck plates. They look like honing plates about 2 inches thick that would go between the block and heads. That's how the they built "mountain" motors in the olden days before the correct blocks were available.

Purecountry,Charlie is telling you straightup about those places that have the big sales pitches. I'm not talking as an expert by a long shot,because I had been doing my own engines for years and finally realized how little I really knew about a BBF when I joined this forum. The info about engines and the BBF humbled my knowledge real quick.
Like Charlie said,read,read,and read some more . The people on this Forum will not steer you wrong. :wink: Rick

I've posted this before but here it is again

Flatlander racing. I'll tell you a little story that everyone should know about them. A good friend of mine runs and owns a race engine shop. They had a customer come in who had bought a complete engine from "Flatlander". He complained the motor ran like garbage. He called Flatlander back and didn't really get anywhere with problem solving. So he brought it in to my friends shop and they put it on a stand and took it apart. The machine work was a bad joke along with all the clearances and other things. The engine owner called Flatliner and said he wanted to send it back. The Flatliner "shop" explained to the customer that they don't do any machine work. They source all the work to one of three shops and they are the ones that do the work. And he had know idea which shop did the work. Flatliner is nothing more then a guy with a computer at home brokering parts from a supplier to you. But on a note of being fair. Flatliner told the shop owner make the engine all correct and send him the bill. And he squared away with him so his word is good. Then a couple months later a rep from I think it was Dart was at my friends shop. The Flatliner issue came up. The rep told him they took one level of parts pricing away from Flatliner because they don't stock anything or do anything. There are plenty of folks on this forum that answer questions for all. Show some support to them and send them your business.
