Does anyone have a website that mentions minimum
cylinder wall thickness for ANY engine?
I'd like to take the next build to the limit of
what the block can take without Hard-Blok
(which my machinist says is at least .060" overbore)
I measured a block and it looks great for even more,
provided I don't violate some minimum requirement.
LMK if U have anything!

I remember seeing those specs but I could not find them anywhere.
Guys if you want someone to build you a motor Robert is the guy. Even with shipping he could most likely beat the local guys in your area in price and at the same time do thing to improve performance that local guys know nothing about

Don't make it sound that cheap Corey!
I'm just starting the V6 engine building, (I've done a shortblock 4.3
and a 4.2 reciprocating assembly so far) but I have a great machinist
that built perhaps the world's first 408 Windsor stroker, before the
stroker craze was even going good! He's really good, he has built
championship winning race engines for several in my area, from
drag race to dirt track and other roundy-round racers, 4 cyl. to Big Blocks!
He's helping me get the stroker V6 program up to speed.
I can build a reliable Power Adder capable 4.5l V6
that is very competitive with SSM's 4.3 and Morana's 4.4

The 4.5 is only .030" overbored,
it becomes a 4.6 at .060" over

Not cheap but where I live these guy plainly rip people off . Here is an example how about a v6 stock rebuild and install 3300 dollars
My problem is nothing in a stock motor is that expensive and installing a motor is one of the easiest things to do if you have the tools and equipment!!! In the past I have taken a engine out to change a clutch assemby over crawling under a car to do the work. If I did not have a place to put it on a lift

That may not be that bad but if you do the
R&R yourself and buy your own gaskets etc.
you could spend the $3,300 on a great shorblock.

Yes on a great short block but not a stock short block. Besides when they were finished reaming him they did not replace much just did some machining.

Well, there's a choice for you.
We could do a big bore or stroker,
I like the bigger bore and 4.2 crank (it's here!)
I like the bigger bore for performance, the
4.2 crank alone is lots of stroke, and if you
really want to slay existing HP records, IMO
a big bore & 4.2 crank is gonna be great.
It can rev higher and breath better with the
big bore, and the heads can be matched to the
bore for max flow. I was leaning that way,
bore it at least 60 over. Custom pistons
are the same price regardless of size.
I'm just thinking of making all my own
custom intakes, I was gonna ship some
business to SSM but Tom never answered
my email or returned my call :-?
They have a good custom upper, but I was
making them long before they did and I can
make them totally custom for a specific combo.

Just clarifying, but you want to bore it /at least/ .060 over AND blow it? Are we talking 5-6psi or whatever boost forged pistons/rods can hold, like we can on a stock bore 3.8l? I'd be mightly surprised to see a 10-11psi blower not jack the heck out of a 3.8 bored .060 over. Are you planning on stroking it to 4.2l only?
For shits and giggles, if you got some spare components laying around, why don't you try stroking it to 4.6l and bore .060 over and try to get 4.9-5.0l and run a modest n/a.
