do they look ok or need feedback asap

 

rods are probably fine, but that piston wither is junk or needs work...notice the crack next to the exhaust relief. We also need pictures of the side skirts to see if there was heat damage.

You can see detonation spots on the outside of the intake reliefs....classic

 

Iam not seeing a crack..but..am seeing where the valve made love to the piston....

Yeah I guess I shouldn't have said crack

 

bump

 

From your pics they seem to be fine. Take some sand paper to that piston and smooth it out and your good to go.

 

ya, just get rid of the valve divot, and it should be ok, also get the rods checked by a machine shop to be sure the journals are round and not ovalled

 

ok im gonna go to machicne shop and see what they can do

 

i'd neve resue those pisotns in a performance engine. the $ isn't worth chancing loosing a motor over. it's a far safer bet for you to go buy a new set than to reuse those that might have issues. also if nothing else witht he chunk of material taken out that could mean a hot sport, and also weight will be off so balancing of the motor will be difficult.

 

ya that piston isnt any good, it might come apart on u, if its slaped a valve it could be close to cracking. not worth the risk

 

definitly check to make sure the pistons are not damaged(little burrs in crown could cause hot spots at heavy loads), out of round or have taper beyond spec. u can use a micrometer, or take them to a machine shop. and you also should have the rods checked for stretching, twisting, bending, and out of round. and make sure the pistons and rods are all in balance, if unbalanced to much it could cause unwanted vibration which could posibly lead to extra stress on the crank and cause shortend life span of the engine. exspecialy with a high performance engine have them checked.

 

if i were you i wouldn't use them, find some new ones or something, maybe just use the rods
