If you want to bore it out to 4.130, or even 4.160, go for it. The normal cylinder core seems to have most FEs cast at 4.36.........we routinely bore them to 4.250 to install sleeves, and you don't strike water. Lots and lots of FEs have been bored to 428 size with zero problems. But there have also been lots of split cylinderwalls. I've seen 390s that had bad core shift with splits in #5, 7 and 8 that were at standard bore. So yeah, you can bore your 352 to 4.130, but do you really want to take the risk ? If you're building a grenade with the pin pulled, well, why not ? If you have plenty of blocks lying around, have fun.
But if you want to increase power with more displacement but want to keep reliability with longevity and no hassles......ask Barry R to put together a crank kit for you with the 4.375 forging. Depending on 30 40 0r 60 over, that should give you something like ~465 inches.
Yeah, you can run the FE with .090 walls in the cylinders and you might be just fine. But with those neat new cranks available, well strokers are just plain fun. Try one, you'll love it. I promise.

I think some have learned a lot about boring and using modern technology to see what you can bore to.We all have had are say about service block lets drop it and move since I started the issue about Service Blocks.Thanks to ALL who have replied about this subject. First and foremost I hope that the original posters question was answered about boring a 352 to a 428? I hope I have not offended anyone with anything that I have said? For the most part, I believe this has been a positive discussion, what do you think? Last but, not least I have a question for all: Do you know the difference between a argument and a discussion? A argument is where two people discuss ignorance. A discussion is where two people share knowledge! My blood type is "B" POS, ha,ha, thanks zrxlover.
