looks just like a valve with the cutter on the bottom. pretty easy better than tearing everything down to get the pistons notch at a machine shop. i did it with the engine still in the car.

Very cool, so you need to buy the notcher cutter blade and then the arbor it goes onto, which I am assuming is different sized according to the diameter of the valve stem guide. So what size are the notchers?

 

[rz5.0]

i know you can get alot of diffrent sizes but not sure what they are

The ones im getting are 2.37" an 1.95" I will post pics and progress

is that for your intake and exhaust i only had to do my intake man its going to suck to do both. good luck

It's always a good idea to do both, but if you really know what you are doing and the cam timing allows it, you can get away with just doing the intake. I have only exhaust reliefs in my custom pistons, and they are tiny ones at that, I think .5cc is all. lol.

I figure once the process is happening it wont take long to do both. The pistons I have are factory 351 forged with the rectangular dishes that are clocked about 15 degrees. It is a ski boat motor it was rated at 346 hp with gt-40 iron heads and gt-40 iron intake manifold. The timing chain cover was even cast iron and weighed about 30 lbs. The block was machined for roller cam but came with a flat tappet cam and lifters. It has 0 mile and or hours on it . The oil pan was a mid pickup pan with oil in it and a filter on the motor. I assume it was started and ran on a carousel. I bought two of them, one is in my 94 cobra now with 396hp at the rear and the other is on the stand getting a little special treatment.

it took mne half the day just to do intake its not hard but real time consuming.i bet youll have to do one pull the head swap cutter then do the other one.
