Hello all,

I am planning to overhaul my engine in the next couple of weeks. My current engine is a 3e carburated engine. I know someone with a couple of 5e pistons that I could get pretty cheap. I was wondering if anyone in here has ever tried that conversion before and could give pointers and was there a difference in power?

I am not familiar with the 3E engine at all (have never seen one) but here's the specs and it doesn't look good:

The pistons in my engine have a dished top and the 5e pistion is a flat top.. and where the valves sit in the head is flat vs a v shape in the 5e.. how do u think switching to 5e pistons will affect compression ratio? u think it would get to 10:1?

Probably affect compression, valve clearances, combustion, and a few other things.

The bore would be more my concern though.
