A few questions about building a performance type 4

2.0 heads can you do a port and polish on them? will it help anything?

I know a 2056 is 96mm bore with 71mm stock 2.0 stroke
is a 2270 a stoker motor or just a bigger bore
what bore and stroke is a 2270

if I go 2270 is 40mm webers enough
or is a 2056 good enough for me w/ the webers


what advantage is a counterweighted crank in these motors

I'm no expert but I have been learning a lot here.

The 2270 is a 96mm bore with a 78.4mm stroker crank. This size will probably need 44mm webers.

You've got to decide how fast you want to go and how much you want to spend...not always compatible.

According to Raby, you don't need a counterbalanced crank on the T4. The case is strong enough to handle the loads.

Good luck!
