Alright guy's.. Pistons came with a long block that I picked up..
SRP #149221 10:7:1 3.4 cc dome...

Want to boost the motor, I Know that I need to worry about the V2P clearances and that it will depend on what cam I go with....
On a V8 motor the min clearance is .100th. I have not been able to any min for a b18.. or else I missed them somewhere. If it's not feasible to run these pistons then I will just get another set no biggie. At this time I don,t plan on running anymore than maybe 15psi boost Max if that.

WHEN ya all get done shaken your heads and lyao, seriously give me some inpurt please, thank you.

 

Somebody,PLEASE!!!!

 

This is what I've found.
