hi,
i was wondering how big of a bore you can go for the 420a engines without putting sleeves and the cc's after the bore. thanks guys.

You really dont want to bore them out but you could get a stroker kit for them. I think thats like 2.2-2.4 l.

just wondering... why wouldn't you bore out the 420a?

I wouldnt go more than .040 over. Just my $.02!

To elaborate, boring is not for increasing power or displacement, its to repair bollixed cylinder wall finishes ONLY. Modify stroke if you want more displacement from your small displacement motor.
