572 cid ford

Was there stroker kit you found advertised as a 572? Just curious where you got this particular displacement from. Most of the larger stroker kits will use a 4.5" crank. Regular bore with this crank gived you around 538CI. If you bore .60 over with a 4.5" stroke you come out around 545. To get to 572 you'd have to be boring to about 4.5" diameter as well. Problem is you don't have enough meat on the cylinder walls unless you have an SVO block. Or maybe they make a crank for regular big blocks which has more than a 4.5" stroke?
I think the most you can squeeze out of a stock big block is 550-560 CI. I just don't like the idea of boring the block that much. Let me know if you've found a bigger crank though, because I want one!

I see a 557 on Flatlander and then a 605 which I believe is SVO only. Am I missing something? 557 is 4.5" stroke bored .80 over if I remember correctly. To be real I don't think anyone will notice the difference in power between a 572 and 557 though. But I personally would prefer to stick to a .60 over bore, a little insurance. Plus if you have to rebuild you still have a little room to clean things up. If you bore .80 over where do you go from there?
OR buy a Lotto ticket and an SVO block.

"If you bore .80 over where do you go from there?"
If your biulding a 572 stroker and bore a stock block most would assume you weighed the pitfalls and made a choice. Also your playing with a cheap disposable stock block, its not a huge loss if it gets wasted...and if it is to you....you most likely would have gambled on it....There are some DO blocks that take kindly to .080 and some may not mind .120 over, but again it boils down to doing the UT, deciding what exactly you are working with, and how much risk you are willing to assume.
BTW- Your correct on flatlanders listing of the Ford 460 Block/557 cu. in. (.080 over)
And that is on a ford block. THe 605 and up are on a FMS or IDT block.

Puller motors much like drag racing motors are often "filled" blocks, where the water jackets are partially filled with a cement like goop for strength.
If one is going that route, you can radically overbore the block to the point the cylinder walls are completely gone, grind, machine and weld together liners, then insert them as a complete unit and braze them to whats left of the block.
Radical machinery, but you can get darn close to 600cid that way. I saw this occur once in my life, and it was an amazing thing to watch, actually.

I found this information listed elswhere on this forum......copy and paste :]
The FRPP catlog lists two 460 blocks & one 429 block, their suggested cid capacity, recommended maxium stroke, and maximum horsepower. They are :
460 (# M-6010-A460)
Max. cid : 598
Max. stroke : 4.500"
Max. HP@RPM : 1,500@8,000
460(# M-6010-A500)
Max. cid : 537
Max. stroke : 4.000"
Max. HP@RPM : 1,500@9,000
429(#M-6010-A96)
Max cid : 600-815
Max. stroke : 6.000"
Max. HP@RPM : 1,600@7,500
The cylinder bore ranges for those three blocks. For # M-6010-A460 it is 4.360-4.600", M-6010-A500 it is 4.360-4.625", and for M-6010-A96 it is 4.500-4.625".

Think stroke not bore. The 460 is one of the best if not the best block for throwing a huge stroke to it. The chevy boys arent even close to this. They have to end with the 502 in the old stock blocks. Ford you can get 593 out of a stock 460 block!
The 572 is a 4.5 bore and 4.5 stroke. The stock deck 10.3 cannot be built to 800 plus. The stock blocks have been know to go .140 over I have only seen a few that could go .110 over with a sleeve or two. I ran a .100 over block for 8 years in my bogger. The SVO can be bored to 4.6 and the IDT can be bored to 4.7 You can run alot more stroke them then the 4.5, we have run 4.6 and 4.75 in these and stock blocks that are highly modified. I agree about the partial fill of the blocks. You can still cool it but you get the rigidness in the lower half of the block. Add 4 bolt main caps or a good main girdle and you can run some pretty stout power through them. After 800 or 900 horse just buy a block for $2000 from IDT. You can get 589 to 593 with a stock block bored .85 over and 4.75 stroke.
