What is the pin diameter for the 340 pistons?

Turns out it was the power valve. Sorry it took so long to report what fixed.
Thanks for the suggestions.

Could it be the power valve maybe?

Mahle power pak piston and ring package.

I have used it in my 385 with a 200 shot.
Very good pistons!

I already have the block. It was done by Carl Hinkson. Very happy with it.
Old rotating assembly was Mahle pistons, Howards rods and compstar crank.
Was wanting personal experience from others on different brands.

I have had good luck with the Mahle pistons I am using now.

Is it acceptable to mount a canister style fuel filter in the engine compartment?
I want to move it from under the car off the frame to clean up the look from behind my car.
I was wondering if it's ok to put it on the fire wall with a heat shield around it?

If you have a 6000 rpm max I would use the dual plane. You wont be losing anything.
