This I understand. But, what about inaccurate initial boring, on a block with core shift?

If anyone want to see what they have, go to their website and you can see all the machines they have, it's an amazing place. It is worth the drive if you live here in Cali to see their shop.

Why are you so concerned?
Both White Dart and myself told you QMP enough said.

If you’re looking to build one of these let us know and we will get to the right people.
If you are just looking to pick at something go elsewhere.

Very well said. Ritter is making a product no one else would even consider. On a limited budget. He has worked his way through his teething issues. THANK YOU to all who worked with Kent Ritter and moved this project along.

As always happens, the cheap asses, whiny Chrysler guys instead of supporting this guy spend most of their time [censored] on them.

Leigh, they sonic every block, trust me you send a Ritter block to them, it's in very excellent hands. They really are a one stop shop for anything.

Thank you for being polite. I was not questioning the engine shop, just inquiring on the technology they use. When my rough bored 1994 R1 block was bored, Tesar Race Engines had to aquire an indexing fixture from Arrington, that was made to print specs. I see the Rmc V3 probes and compares to print. As far as sonic checking, yes, I'm sure they do. Good luck with what sounds like a good, solid platform.

I can see your where you are coming from, trust me I was worried too about core shifts. But this blocks due seem to be minor if not at all. Maybe not all blocks will go to the 4.220 bore they are suppose to but these blocks are solid, thick in areas that much needed it. If you or anyone has questions feel free to ask those of us that have them.

I will say this, Chrysler is well over due for blocks (big and small)glad to see this.

We are pushing for four digits.. out of an N/A.. we have gotten close.. but not there yet the motor is back apart looking for a few more HP.. my block is still leaking water through some porosity into the crankcase.. going to try to seal that up with epoxy.. keeping the water out of the oil on this block has been a challenge.. Granite this is second generation I know Bob's block is a 3rd generation.. which I am told is a nice piece..

Very cool Shilo i know you will find that extra hp somewhere. I going for 4 digits as well with pump and race fuel.
Bob what's your goal for your build?

Where is the porosity? I'm not all that familiar with cast iron casting and what cast iron those blocks are (I'm doubting they are CGI because they'd be more expensive) but I'm told the pour is too cold when you get porosity.

I believe the R series and R1 blocks were machined with factory style tooling and fixturing, which wasn't as accurate as much of the aftermarket CNC machined stuff now.

Well if I'm going to help Shiloh against Chevy and Ford I need to be in the same ballpark (4 digits). I might have to go to the next head program to get what Shiloh is after. I have a few things I'm going to try before more head work but I'll bet the heads need to go back to Brett before we reach 4 digits.

You guys need to understand that Brett, Shiloh and a few others are getting ridiculous numbers out of these small blocks. I'll see what I can do to make sure I'm not way behind once I get my deal going.

I here you on that, not sure if I'll be the first to force induction these block but we shall see, nice thing with turbo there are easy in the internals. And I'll take mine out to local events to also help you and Shilo take on them. Though mine is also a street car. Will be fun either way.

There is a place that my buddy knows that fix this. Its a new process they do on porosity blocks. I well get the number for you

He is super busy
This fixes porous blocks
**This will not fix Cracked Blocks**

Thank i will look at it

Matt.... was your block prepped for 59 degree? If so did it come that way from Ritter, or did QMP do that. Guess I’m just “assuming” looking at the machine work on the block.

It came that way from Ritter, QMP just inserted the sleeves and made them a little bigger to .937

Hang tight and in a little Dart will have a quality block with no worries about its quality..
