Max the Kit is ****, Actually I lost power on my 583, I know of a few other dd`ers that found the same. I found more peak power and torque by playing with my cam timing last season.
Sell em on flea bay and drop in a 900 lump if you want more performance.

LOL not the 900 lump, but then again is the 675........LOL
I suppose you have to get caught with it...Dry clutch may give the 900 away tho.

bloke on the UKMOC site is looking for a 675 kit

Is the kit that bad? Cripes – I thought it was good for a little more torque?

As for why I’m fitting the kit… It’s a short and sad story…

I have bought a House, thus I’m absolutely fricking broke. Racing in 2007 is on hold.

I’ve had my 600SS since it was 3k miles old, now it’s done close to 40K (and last years racing!). I have always changed the oil every 3K and measured the valves every 6. The result is that for a bog std 583, she goes really well, great oil pressure and uses no oil between services either. But she don’t half slap that Horizontal piston about!!!

Hence the thought of utilising the 674 kit in my garage. Unless anyone else has any ideas? Like selling the kit and getting a new 583 piston ring set?

To be honest I’d rather run in the 583’s again, but I have a kit for the 674, already paid for and doing nothing…

As I was running std cam timing… what is this staggered key business about? Can I get some? Recommendations?

"Staggered keys" are used to "blueprint" the timing as there is a degree of tolerance on the valve timing in standard form. You could use the keys to alter the timing slightly but it seems that by ensuring the standard timing is spot on you can expect improved engine performance.
