OK, got the trickflow heads off you guys identified for me. now I am trying to identify the pistons. can anyone identify this one? no marking stamped on exterior and dont have the engine out of the car yet to look for numbers on the inside of the piston.

anyone care to take an educated guess?

 

no but this belongs in general discussion....

 

look stock to me

 

my dad just bought a car and the motor that came with it had pistons like that too.was told they was stock.

 

Dude, I think you got ripped. Didnt you post before about that was supposed to be a 347 motor? Those look like stock dished pistons to me...

 

Looks like stock 87-92 pistons:

 

stock oem

 

That really blows if they are stock. Yes I was told it was a 347 motor. Well i guess im going to have to find me another engine to put the heads on.

On a brighter note though, the car ran 12 teens on motor with what is now looking to be a trickflow headed 302. So my goal of 11 teens on motor should be no problem once i have a true 347 with the upgrades I already purchased.... the stock pistons are still forged correct? basicly i just dont have the stroke i was told correct?

Still sucks that the guy lied to me though

 

You need to do what I told you to do, before.

bring one piston to BDC
put a straight edge across the bore
measure the depth of the piston

it should be 3.4" for a 347

 

Yes u can get aftermarket pistons that look the same as oem would be wise to check the stroke!
