You need to check with who you got the crank from. Some aftermarket cranks have a different radius on the edge of the journals than a stock crank has and requires the use of a bearing such as a Cleveite H series.

that uses bbc rods and ford mains.you realize with a 4.140 stroke you have to bore the block .080 to get 514.your going to have to make sure the block can go that far.if you had gotten a 4.300 stroke you could get a 514 with a stock bore,521 .030 over.

I always check ebay to see what else is out there. Sometimes it's a good deal sometimes not. But it does give you a few more options to look at.

Your right, most of the comments I read said the cranks weren't the best. Some said the cranks were textured like a cob after you remove the corn. Also a lot of issues with balancing the rotating assembly due to piston/rod clearance or internal alloy differences.

go with the scat or eagle crank, and run federal mogul 134M bearings (summit part number FEM-134M) it's a competition bearing with the wider radius for most of the stroker cranks, I run them and abuse them without trouble. and for the rod bearings just use the standard size BBC 2.200 rod bearings something like the clevitte P series or H series will work on that crank.

I just ordered the scat crank. NOw im wondering about connecting rods. I think i need 6.700 and 2.200 right? Aslo i was reading and it said 6.700 is minumin, so does that mean i can go with a longer connecting rod? And if so how long before my pistion will be hitting my heads?
Thanks

Yes. A kit is the way to go about this. You will get a crank,rods, bearings,rings and the correct pistons in the compression ratio that you need. They are usually cheaper than pieceing one together.

Direct answer to your questions is yes 6.7 is the minimum, I never liked kits personally because you get what someone else thinks you need. You can run the 6.8" rods on that crank and then you have to order a piston that is setup for the stroke rod combo you went with.
