There is no such thing as a 1300cc monster :) It really depends on what you want to achieve. A torquey motor for around town or a narrow power band screamer with a 9000 rpm rev limit?

Big valves, dual DCNFs, higher compression, better cam, better exhaust from the head on back.

There is a lengthy thread here you should read:

Lol. Don't be mean 😥 😂 Ok thank you
 
First you start with a 1500 X motor. Your original question needs more context, what are your plans for this car, street, track day, race?
 
I've seen a couple of Fiat 128 1300 "monsters" at classic racing events here in Sweden. Or to be true, all of them are stroked to 1600 but of course, the owners do not admit it. And the amount of money they spent on the engines is crazy. No way they could be faster than most Ford Escort Mk11600 without cheating.
 
There is handbook out there which i think its pretty cool.

The Fiat SOHC engines respond to modifications just like any other engine. Get more airfow through the engine and you'll get more power. The problem with the 1300, relative to the larger 1500 &1600, is that it's small. There isn't a lot of potential there. On the bright side it's larger than the 1100!
