Your probably riight the 184c specs would work better with even higher cr and diff valves but. Even on a lightly touched head and only 12.5:1 cr they make more power everywhere then then n1s more everything everywhere. The tq was huge.

You used the 184c's when you were at stock bore?

No I didn't get my set till after the sleeved block. But others that have run them on high comp 2.0s have done well and have made more power then n1s aswell.

I reckon unmodified sr16 pistons is the ticket for 2.0L motor and 184c's
Thats what i'm doing. The lo lobes have enough overlap for it.
I've just picked up some second hand franklins s4's so the motor will go together with those then i'll switch over to kelfords when I can afford it.

The problem is not overlap.

The problem is airspedd and port velocity. If your head wont flow enough then the 184c's will stall up.

I think what he is trying to say is the added overlap on the low lobes will lower the chances of detonation on the low lobes,

I'm well aware of that too,
I will be building up the floor of the port and reducing the area of the port to get a better velocity for the displacement and rev's I want to pull

The standard port size is about spot on for a 2.3/2.4 at 9k. I.E. too big for a 2L.

My comment about CR was more that I think these cams would happily/safely take more compression than people are running on them

Still need to finish building my flow bench and the race car before I can even begin to look at my motor anyway, but its going to be a bit more than the average bolt ons and n1's.

back on topic though.
N1's are always going to be a safe bet

Has anyone tried the 184-D, on paper they should be every bit as good as N1's but bit better down low
