Excellent link to a Dart 351 buildup to 427!

[madmaxx]

If you guys think it is easy stroking a 351 to 427 take a look at the following link. It highlights the advantages of a Dart Block. You better trust your machine shop. The way I calculate it cost about $9500 in parts and throw $1K for mahine work and you have $10,500 and you have not even put it together!!! I have no idea how these engine builders make any money.

I don't understand some of their reasoning. An Iron Eagle block (which is rated for some mondo horsepower with all 5 caps being 4 bolt) for an engine that may make 550hp. Why not an SHP or a Sportsman block?

Professional Products intake? Please.

Seems like a lot of wasted money on parts that they didn't need and a lot of corners cut on parts that could make more horsepower.

I thought the problem with the Ford Sportsman would be cylinder wall thickness when stroked to 427. Maybe not since ford is offereing a stroked 351 to 427.

I was referring to the Dart Sportsman block, not the Ford Sportsman block.

Also, on a block with 4 bolt caps on all 5 mains, you have to watch about oil pan fitment, so you may have to hunt for an oil pan that's designed to clear them....either that or "persuade" it.

I thought that was the sportsman block, from what I understand the only difference is one is set up for a dry sump system which they are not using. I suspect components were "donated" for free from manufacturers. When I added up the parts I assumed the sporstman block from Dart.

I wonder why in stage 2 he refers to afr heads but goes with trick flow in stage three, it appears there will be a stage 6 with a dyno, should be interesting.

They should also consider Dart heads. Dart is well known as dominant supplier for aftermarket BBC/SBC heads for years, but their SBF heads deliver excellent power, high quality, and are competitively priced. I am very happy with them on my 418W.

The Iron Eagle Sportsman block has 4 bolts on the three center caps. The two outer caps have two bolts. The regular Iron Eagle block has 4 bolts on all five main caps.

Both blocks can be set up for dry sump.

Dart also has a new block for Ford engines, called the SHP. It appears to fall between the Sportman block and a stock Ford block, for a few hundred $$ less than the Sportsman.

I agree. I have them on my 427, and they make excellent power. Pretty resonably priced, too.

If you want to see how to do one of these right with good parts just go to our website. We have a complete dyno tested 427C.I. 351W with the Dart Sportsman block. It comes from carburetor to oil pan with the distributor, wires and water pump. Our standard version makes about 580HP and 560 ft/lbs of torque. We custom build these for each customer and can taylor them to each customers needs.

Thanks, Keith Craft

I saw on TV this weekend that Dart now offers a short block with forged steel components, built to order.

I just provided the link to show some of the skill and experience needed to build one of these engines and have it live. If you are in the market for one of these, call Keith Craft and let him do it for you. There is no savings in doing yourself as I stated parts and machine work are North of $10k and does not include assembly. In addition he knows what he is doing and for icing on the cake having a KC engine in your cobra adds value over a home built.
