What is your plan?
1#Do you know what your max RPM will be, or you want it to be?
2#And what max power you want? This could impact max RPM of course.
3#And is it gonna be a carb type intake or injection?
Intake runner length could maybe be an issue to get OPTIMAL, if you are gonna run low RPM and carburetor?
ITBs could maybe flatten out your power curve.
But why not just have a "really big" engine with a small cam, and small runner heads, then you can have that flat power curve in a low RPM?
In my opinion I dont see any problem with an longer stroke than bore, my short deck 1.8Litre VW has 3.18bore 3.40 stroke and short 5.66 rods and makes peak HP at 6100. The stock 2 litre has 3.65 stroke I think. But if the bore gets to small compared to the stroke/total engine size, I would think the valve shrouding or size would limit the power potential. Especially in a 2 Valver.
If you increase the bore too, you would get even more bottom end, and probably more everywhere, so why not more bore too?
(This is like an modern 305 vs 350 discussion, the 305 too has 3.78 bore) I have nothing against 305s though, I like difference.
