[QUOTE="Rossim22, post: 11650665, member: 103156"] I currently have a teksid block, diamond pistons w/ 9.1:1 cr, arp hardware, then reused rods, crank. About 6 months ago, the heads had a valve seat come loose, never dropped. the heads were replaced with oem w/ a valve job and bottom end inspected. Went to shop #2 for tune and n2o install put down 525whp/665whp, then went return fuel and power dropped to 505whp. Then after repeatedly going back with small driveability issues, all was good. 3rd run on blower only (never hit the button) the motor got hurt. The shop that tuned and did most recent work is paying for parts and labor and theyre in the process of tearing it down now. With a quick scope of the cylinder it looks like a piston kissed a valve on driver side and broken ringland on passenger side. If there's enough damage that a new assembled shortblock would be more cost efficient then we'd go that route, I can pay for upgrades while we're there so I'm trying to get an idea of what to look for and what application best fits my needs. I'd like a tame DD that makes good power on my posi ported eaton and extra n2o to take out the big guys, the car rarely sees dragstrips. So far my thoughts are 5.15 Boss from MMR w/ 9.5CR but a lot of local guys don't like them and claim they can be trouble. [/QUOTE]
