Hey I'm jus double checking before I throw together this motor. My 97 xj #1 piston self distrusted in block so I bought a 90 rennin block and head for 50 buck and wondering if I use renix block with all ho stuff that it wil have any power loss. I'm planning on using the ho cam head intake and exhaust. Only using block from Renix . Heard the casting was a littler tougher in the renix. I have a 89 on 36s and boiled it several times so I pretty sure the renix is a tough one. Well let me know. I ve searched jus trying to find someone that has done this. Thanks
