OK, I've searched the threads and have come to the conclusion that using a 4G64 crank in a 6-bolt 4G63 motor has very little negative side effects, and quite a bit of positive reasons to do it. I am building a 6-bolt from scratch right now, and it's time to buy pistons. Should I go with a stroker crank? Are they 6-bolt? My main concern is any extra machine work that will have to be done to make it work. Does all the OEM 4G63 parts go on just as if it were a 4G63 crank (bearings, front seal, rear seal, harmonic dampener, timing belt gear, flywheel, etc...)? I know I will have to get the Wiseco pistons that are made for this. I already have my Crower billet rods. I need to know if anything must be done different (besides the pistons) to make this work right. I'm trying to think of everything during the rebuild because I don't want to tear into this motor for a long time, so I'm over-building the thing. The extra displacement sounds really tempting. Any help on what I need that's different from using my 4G63 crank will be great.

It looks like $300 is about the going rate for a 4G64 crank. Does that sound right to you?
 
I actually contemplated mixing engines together, such as a 4g64, and then a 4g63/64. My opinion is to just stay with a 4g63, you will have less problems and much less fabrication not to mention a million after market parts are made for it unlike the 4g64. But if you are sure you want something else, just use the 4g64 block with a 4g63 head. You will NOT have clearance issues.
