hello !!

sorry for my english, i'm from france.

 

My 3KC is now in bad condition, so i will rebuild it soon !

 

Then i want to mod it a little.

 

I will do some head working, change the cam, change the carb, and put some harder valves springs.

 

where can i buy some harder or dual valves springs ? and cam ? (maybe i have found the cam, but there is only one...)

 

Could you show my some modded head ? and tell me what is good to do ?

 

Where can i buy some good pistons ?

 

AAAAAAAH last question > Will 4K pistons fit my 3K block ?

 

 

If you got any idea of good mod, tell me :lolcry:

 

thank you very much :hmm:

Please, i really need to know for the pistons... if 4KE pistons will fit my 3KC. :lolcry:

Yes, 4k pistons fit a 3k. Because a 4k is basically a stroked 3k, and a 5k is a bored 4k.

Can get ACL pistons at a pretty reasonable price.

 

You've only got 1 cam cause that's all there is! K series engines are OHV (over head valve), not DOHC (Double over head cam).

 

Its not hard to get valve springs and cams here. Maybe you'll just have to pay freight if you can't get them there.

 

Usual type of head work is port and polish, valve re-grind, maybe bigger valves, stiffer or double springs, as you've said. Depends how far you wanna go. Speed and power cost money!!

Heres a pic of some decent sized ports compared to normal 3/4k size.

 

Other thing to remember is though, if you're going to put a cam in and port the head etc, you really need some extractors, decent exhaust, and a weber or similar carby. You should be able to get a suitable weber pretty easy off a alfa or fiat. Something like a fiat 128 carb is perfect!

 

I'm not going to tell you any more mods to do, go have a look in the members rides, and see for yourself what else is possible with these great little motors. :lolcry:

hey :lolcry:

 

thank you very much for all thoses informations !

 

i really want to make my engine going well, that's why i ask a lot of questions... ^^

 

i will try to find some parts in this message board so

 

if you know a good website to buy some parts, tell me :lol:
