just do .20 over, our engines do not make more power from a bore... i just went there yesterday to drop my block off i would get the evo pistons too.

You should give them a call, they are great guys to buy from. As of oversize, if you plan on keeping this motor for a long time a .020 oversize is the best way to go, it also gives you room to move on your next build.

Do they do balancing and blueprinting? I sent them a message and haven't gotten a response yet about their head work. :[

what about the block?

 

[grimdsm]

They had said they are just now starting there head work and getting it up and running just email them and you should get an answer pretty quickly

I got my Frankenstein 7bolt block from them last summer. Good guys, I talked to Jon and we worked everything out good with bearings and rod bolts that I wanted. I think it'd be best to call and talk to them, you never know how much damage you have on your cylinder walls until you take it apart.

The turn around time on my block was slow, but I had some mishaps with shipping and what not. Block spun nice and freely when I got it though. The sad part is I have yet to have my car up and running so I couldn't tell you how well it performs.

THEY ARE NOT REBUILDING MY BLOCK!!!!! THEY ARE MAKING ME A CUSTOM BUILD ! i just wanted to know what a 2g thrust washer was compared to a 2g flange bearing . and if going from .02 oversize to .04 made a difference in performance or chances of me blowing my engine.

 

[grimdsm]

i would recomend trying to get thrust washer instead of flange bearing... but thats what jon recomended

I believe the flange bearing was linked to plenty of 7 bolt's crank walking. There will be no difference in performance between .020 and .040 over. If are cars had 8 cylinders it might matter but we only have 4.
