Bill Mitchell 460 small block
I saw this on their site where it's over 600 HP and you have the choice of carb of fuel injection. Anyone running this? Sounds like a great idea with the aluminum block. Would be even greater to put the Dynatek fuel injection on it.

hello Scott;
We (Suncoast Carcrafters) are presently installing a "World Products 460" with Accel F.I. in a Everett-Morrison car. World dyno sheet shows over 600hp. We have had this motor for some time in another car and had FI and other problems and sent it back under warranty. By the time we got the engine back, we had sold the car it came out of. (installed Roush unit as customer requested). So the engine had been setting waiting for a car when we decided to put it in our EM. We are anxious to see if the problems have been resolved, but we still have another week or two of work to complete the car. will post results at that time. |
Hi Scott,
I have a 461SBF and i am very happy with the engine. It's not from Bill Mitchell, but i did speak with them about their 460 on more then one occasion. They went out of their way to answer questions, and gave me detailed data on the engine even knowing ahead of time that i was not buying, but seeking information. I believe the dyno sheets averaged around 618 and 585TQ ( I may be off a little its been a year or so). :) |
Maybe you should do a search on Bill Mitchell, world products motors on this forum, and maybe others.

If this is a small block the connecting rods must be a very severe angle. Is there a durability issue?

Interesting engine. However at those prices, it would make more sense to build a high end FE for a Cobra -- just one opinion.

Guys they have been selling this engine for a few years. Its one of there top ford sellers. If the engine was a problem child they would stop selling it. It has the same warranty as their other engines.

"If this is a small block the connecting rods must be a very severe angle. Is there a durability issue?"
Bob is referring to the rod length to stroke ratio. Web sight doesn't list rod length. |
Thanks for all the replies. I'm curious to know some of your opinions on the ability of this engine light weight vs a aluminum FE 427-482. Sounds like it's similar for the output (HP & TQ)? If set up correctly with efi, could really be a terror on street and track. What would you expect to get for a lifespan in terms of miles? Would it be better to go with an aluminum Keith Craft 482 that would be similar in power out put and get a longer life?
I've read the threads associated to big block vs small block with ability to rev faster, etc. It would be nice to have something closer to 600 HP & TQ but also get more then 20K in mileage. What do you think? |
460SBF = 6.3 Rods and 4.25 crank = 1.5 Rod ratio
Stock Small block Chevy 400 = 5.7 rods and a 3.75 crank = 1.5 Rod Ratio **) |
IMO, the only advantage to an FE is the look. If you could have the same power for less money, in a smaller package, with less weight, why wouldn't you?
But, that's just my opinion. I could be wrong. |

I've been reading some other threads about having a 482 FE aluminum. It seems we're talking about approximately the same price or there abouts.
Questions: 427 SBF Aluminum weight vs. 482 FE Aluminum? 427 iron weight vs. 482 aluminum? 427 iron weight vs 482 iron? Does anyone have the approximate weights? I want to say the 427 SBF Aluminum is about 475 lbs or so? Sound about right? How competitive would the 482 FE Aluminum be with a 427 SBF Aluminum (assuming both were set up well by a professional)? I'm talking track times both a road course and 1/4 mile times assuming everything else were similar with both cars minus the differences in the engines. Would you expect to get 50K miles out of the SBF? Or more? |
I'm running the 8.2 deck height engine SBF block with 347 stroker kit.
Am very pleased; bought a prepped block & installed engine internals myself. The block has alot of useful features, but the "handbook" is quite vague at some points.. For instance, there are 3-4 possibilities to hook up to the oil gallies- both front and rear- but no pictures or anything to show where they are located. I'm installing a Accusump and think I will use the rear location; will have to undo the plug to check if it's the correct one... I assume the 460 is based on a 351 Tall block SBF? On the weight of the block; I did see some numbers... If you compare the World block with the Ford Racing "Boss" block, you will get a hint. The World Aluminium is lighter. I think it came out like this: The WP alu block is about the same as a factory block while the Ford 4- bolt Boss is heavier... I don't remember if Ford Racing does have a tall block for comparison; they might. |
Scott i sent U a PM.

351W all cast iron 510 lb -- Block with main caps 165 lb 427FE all cast iron 670 lb A Dart 351W is about 195 with no main caps, so block choice can make a difference. I have no data on aluminum blocks. Obviously aluminum in a FE will save more weight than a Windsor, as it is a bigger block. An aluminum FE will get you down near a cast iron Windsor, but an aluminum Windsor will be lighter yet. It would seem to me that a 427FE head with the big valves would be easier to get flow out of than a SBF head. FE stuff costs a little more, so it would be hard to guess which head would cost more to get the same power out of them. Barry or Keith would know, as I am making a lot of assumptions. In a Cobra, I think when the price and Hp is close to the same, a FE is the no brainer, from many points of view. If all out performance was the goal, I would go Windsor. If we were talking a newer Mustang, the Windsor. Just one opinion. |
