What were the part differences between the stock US mainland Honda 600 engine and the Hawaiian version?
Was it more than the cam and exhaust?
Do both have the same cylinder head and pistons?
thanks,
Dale

Hawaiian engine
Re: Hawaiian engine
The differences in the standard engine and the hawaiian engine... the
hawaiian engine had a more advanced cam i believe, someone quote me
if i am wrong and also the hawaiian had a larger carb. as far as
looks i am not sure if there was any. hope this helps.

Re: Hawaiian engine
Dale;
This is not an easy answer, as parts manuals for different countries support different fuel intake systems and our best bet is the Parts Mauals.
The Parts books printed after 1970 do not show the intake manifold change for engines built after 1017731, the camshaft housing changed after engine number 1013113 for all 600's and again at 1017731 for US (KA) models. So this means that Hawaiian engine production could be 4676 units built. With another 554 units built with the angle port head and using the Y exhaust system but had the smaller carb (to engine number 1018285), which is supposed to be the last engine built with the Y exhaust according to the 1972 Honda 600 Sedan parts manual. However, that same parts manual does not support this by stating that the single exhaust pipe with Heat exchanger started with engine number 1020209. This is where the discrepancy lays because there are 2478 numbers between the last engine that had the Angle port head and exhaust system and the first engine with a single header with heat exchanger. Some of these engines could be written off to testing but I think there is a stop and start in production for the US market, with some of these cars going to places like Guam, Panama and Bahamas. These areas are/were protected by the US and could have seen shipments going there, although I have no supporting documentation on this.
The best information is that Honda built 13054 Honda 600's before sending anything to Hawaii. So there are lots of Angle port heads, Hotter Cam's and larger Carb's in the rest of the world.

Re: Hawaiian engine
Hi Bill,
Thanks for the information.....it was very helpful.
All this was prompted by the msg from Tom about his coupe being rebuilt at B & B Automotive. About 20 years ago I met B & B (I think it is Blaire & Blaine) at a Honda 600 cruise someone in the area had arranged. B & B had a 600 coupe which looked stock but when I was travelling up a hill, I saw their coupe accelerate past everyone. When I asked him what he had in his engine, he was very secretive. I figured he had the Hawaiian cam in his car. Or maybe he had the 12:1 compression kit which was offered by J & J in SoCal which consisted of a special cam and higher compression pistions/rings.
From your msg, I am gathering that if I wanted to modify my stock 600 engine to the Hawaiian version, I would need to change the cam, cylinder head, carb, exhaust, and (possibly) the intake manifold. I think the tough part would be obtaining or making the cylinder head.
thanks again for your help,
Dale
