A KB block w/ B1 heads is gonna be a pretty serious piece. I'd put some quality, higher end, parts in that build. A good engine shop could put together a "kit" for you, but I doubt you'll find any online mail order kit like that.

I worked with Chip at Ohio Crank and am very happy so far with my 451. I would give them a call and see what stroke/rod combos they have available (way more than what's listed on their website). I was able to pick the Piston (Diamond with 1 free spec change), the rings (gapless) and the bearings I wanted without issue. He worked with diamond to find a Chevy piston that saved me from having to deck them for my compression height. Paid for the kit, had it a few days later.

You won't find a kit. B1 heads have a different valve angle than say Indy's or Trick Flow, so there are no shelf pistons available. Plus, the amount of power that the B1 heads can produce are more than what most "Economic" rotating assemblies can handle. You are going to want some good parts in that combo.

I would call Koffels they might have the parts on the shelf for that combo

What size is the current bore?
On your deal I would look at buying and using a 4.25 billet steel center counter weighted crankshaft(check with Ohio Crankshaft for a good deal on them ) with either BB Chevy 2.2 or large journal SB Chevy 2.100 rod journal sizes and good set of rods, steel or aluminum and then the best custom pistosn you can get with .043,.043, 1/16 oil rings set up for a vacuum pump, no gapless rings
The B1 heads and top end parts you have now will rev to 8500 RPM pretty easily with all the other good proper parts to do that, if your willing to do that then buy the good parts now while every thing is still in good shape
I have a new high nickel cast iron 4.500 bore size Koleno block and a set of B1-MC heads with Ti intake valves that I am planning on building a 555 C.I. bracket motor with a old used Sonny Bryant top fuel forged steel fully counter weight 4.375 stroke crankshaft with BB Chevy rod journal sizes and all new parts to achieve near 1000 HP on E85 fuel with a single large dominator carb., or maybe two 1050 CFM Dominator carbs on a sheet metal tunnel ram on E85 if needed

NO!

Just bite the bullet on price and get real American parts. Bryant, Callies, Crower, ect...

JE, Ross, Diamond and ICON ca get you the right piston.

Another option on rods and pistons is BME. I can get you a pretty good deal on parts from BME.

Still not cheap but some of the best parts around.

. This for sure!!!

And I'm sure Diamond or any major piston manufacturer has, or has the ability to create, these valve angle pockets. He won't be the first to run B1s I'm sure.




440 Source has trouble centering a crank seal in a timing chain cover...so I don't trust them with rotating assemblies in the slightest.

The OP asked about a stroker kit. The point is that there are no "in stock" pistons that will work with a B1 cylinder head. Any company can cut some pistons. But he shouldn't trust a salesman looking to make an end of the week quota that tells him something like they are "Universal Fit" or "They Fit All Wedge Heads".

When you build combos with higher cubic inches there are so many ways to get where you are going. My 572 combo I put together in 2009 had a set of Indy pistons cut for 440-1 heads. I then had them cut for B1’s also. It had a stock length 440 rod in it. The 572 I am building now has a 7.150 rod in it. I see lots of used pistons out there but you won’t find many on the shelf. It doesn’t take that long to get a set of custom pistons made

So then OP shouldn't order a stroker kit through a Jegs or Summit hotline.

If he calls Ohio Crank, they will piece together a kit with what he needs, by working with trusted and proven vendors. I doubt Diamond or any major dealer is going to risk their reputation to meet an imaginary quota.

Diamond gives you one profile modification for free. It's not uncommon to have to get non-standard pistons. These are cylindrical slugs with relief cuts...not a space shuttle engine. You said it yourself..."any company can cut some pistons".

Good to know that Diamond will help with custom orders like that. As I'm finding out, building a B1 engine is just slightly higher in price than building an Indy head setup.

Just buy rods and pistons from venolia. Great price and good lookin parts.

I decided to stay at 499 ci and ordered rods from manley and pistons from icon thanks for all the help Matt.

ICON knows all about B1 Heads, ask for Daniel.
