69 Z, Headers, VS Stock Manifold and Chambered

[NEW]

I have a 69 Z, it has now a completely rebuilt engine,
0.3 overbore,with standard GM pistons standard Camshaft
and the standard 2.02, 1,60 Heads, The engine has been slightly top decked.

I have for now the oiginal intake, but has also been running it with my Crossram.

Anyway now the qusetion::::

Has anyone here tried swithcing from stock exhaust manifoilds, and chambered exhaust to something like Hooker headers and a little bigger exhaust system like 2,3/4" or 3".???
What is your experiences, there is no punch in the engine and i am thinking it could be the manifoilds that is to restrictive?

And does anyone know what jet sizes is best to run in the stock Z carb, aaaaaaaaand some more, does anybody have recomandations regarding crossram intake, and jetting, maybe it also would be better switching for 1.st design camshaft...

Any tips, or info from people that has tried diffrent things, or people in the know of something pls. Reply..


In advance, THANKS
