Ok we all know about the 460 but now i here talk about the 514 or 521 or 545. Are these just a bored out 460 or are they a totally different engine. Im not familiar with the high perfromance Ford engines after the 460. So Im just learning all about these motors. Thanks for any help to a novice here.

 

all those are a combination of boring and stroking 429/460 (385 series) engines.

 

Do you know where i could find out the bore an stroke off those engines? So there all basically the same engine different bore an stroke. How about the intake an cams any differences there? Thanks for the reply.

 

well they are not factory production originally.. they are "kit" engines
501,514 4.145 stroke 30 over and 80 over OR 4.3 stroke no bore
521,532 4.3 stroke 30 over and 80 over
545, 557 4.5 stroke 30 over and 80 over
thats basically how it goes... you may get a different # here or there but that should get you in the ballpark
you can find that out by searching "460 stroker kits" it will tell you what it makes.. Intake and Cam are up to the buyer (you) it really depends on what you are doing with the engine. MOst of the Stroker motors i see generally have a Victor on top of them, or the Ford Motorsport intake (same thing) if you want it for towin or low rpm use the Weiand stealth seems to be the most popular intake.. i think they work very well. cam...well..gotta know the application

 

Ok now whats 30 over an 80 over mean. 80 thousands 40 thousands is that correct. Who sells these kits. Ford racing or others. Thanks for the reply. So basically all that changes when the motor is bored once is the stroke. Sound right.

 

yeah. 30 and 80 over are thousands of an inch.
Scat and Eagle are popular kits.. but there are lots of companies who make them.
you'll see the bore sizes listed 4.39 (+.030) or 4.440 (+.080)
doesnt matter if its originally a 429 block or 460, bore size is the same between them 4.36.

 

my 514 has 4.44 bore (80 over) with a 4.15 stroke with chevy 6.8 rods. seems to be a lot of exotic rod combinations.

 

my kit has 6.8 rods too, most, if not all the 385 strokers i've seen run chevy rods, 2.2 journal 6.7 or 6.8 rod. helps keep the cost down. some of them you do have a choice of the piston pin diameter.

 

The ford motorsport 514 is actually a 521 4.3 stroke 4.390 bore but the reason ford called it a 514 was the original ones actually used new production blocks and standard bore but ford either ran out of new blocks or figured out that used seasoned blocks were causing less issues. The reason I bring these engines up is because ford used a odd crank that DID NOT use the BBC rods but actually used the standard BBF 2.5 rod bearings and the standard 6.605 BBF rods.
I can list you a bunch of places that sell the stroker kits like ADPerformance just as one example or performance crankshafts I think even Summit and jegs sell BBF stroker kits. I happened to piece mine together by buying a crank from one place, picking up a set of 6.8" rods, bored my block to .060 overbore (odd ball combo requiring custom pistons but I had to special order my pistons anyway due to using A460 heads and wanting domes for higher compression ratio). the current project I have picked up a set of Billet 6.7" rods and will get the pistons ordered when I do decide what heads I want to run. This is important to know because you REALLY NEED to decided on what your doing in advance and what heads your going to be using because things like the FRPP SCJ and the Kaase P51 use a differnt piston from factory iron, and the A460 style heads use a different piston yet and if your looking ot really go all out the Boss 9 or Kaase reproduction have a special piston for them or you can get into the C heads etc (don't even think about those unless your running an aftermarket block and at least a 4.5" bore)

 

Most that i know of are strokers. ford 460 rods are heavy, and aftermarket rods for them are $$$$! So a comon fix is to ofset grind the crank to the outside for the bb chevy rod. You save weight on the crank and the rod, and pick up CI's by doing it.

 

The big thing now is that it cost more to offset grind a factory crank then a aftermarket cast steel crank that is stronger and new and already comes setup for BBC rods plus you can go a lot further then the factory cranks would allow for adn there is off the shelf pistons available for this.

it's been a lot of years since it was of much benifit to offset grind factory stuff, yes that used to be done and it still can be but really doesn't make sense anymore. and if your looking at big HP for the money you will have in the machine work on a factory crank you can almost buy a forged steel one that will support 1200+hp

Also they don't use actually BBC rods just ones that have the bearing and pin dimensions.
