Hello, Im in the middle of doing L28et engine swap on my 75 Z. I bought the engine ages ago and now finally getting around to it. Its a P90 head and F54 block. It didnt come with a distributor so I had to buy one from someone on here. I found it odd that it didnt match up. So ass Im taking apart the engine, I take off the head and I see flat top pistons.
Do I unfortunately have an NA engine? Is there any other changes, other than the pistons and the distributor shaft?
Do you all recommend I change the pistons to dished? Is it as simple as that?
