So did anyone get this kit done yet. I have a superjet now that has 62T cylinders out to 760, done over stock 38 carbs, high comp westcost head, and factory B pipe. I think somtime this summer or maybe next fall is when I really want to step up power. Now that this kit is out I dont know if the group k kit is the way to go or do I try to go witha stroker setup? I have herd all different price numbers on stoker motors. The only shortblock stroker I have looked at yet is by thrust innovations and I think I runs right around $4800. Anyone want to point me in the right place to shop around for a storker?

Team Scream has excellent references, but we would like to know about the GroupK kit as wel... since this is the thread about it... so anyone has it in their RN SJ?

This thread is about the GroupK motor.
I have moved the other posts to their own thread here

Please keep this one on topic.

bump - anybody at all?

Wondering the same thing. I was REALLY happy with how my 750K runs, that Harry did. I would really like to try an 850 out.

I think that the good think about GroupK is that for them power is not everything. From the multiple readings from Harry I get the impression that:
1. Sheer power is not key
2. They ARE cost conscious: if it is not needed, dont buy/do it. Personally I am not sure what is the big fuss about DASA if they cost 2 or 3 times more and usable power can be similar. Of course if you want billet everything.....
3. Relaiablity is crucial

Just my 2 cents..

its more than just bling, the # of transfer ports, as well as the option for powervalves if you want to run them

IDOK, I agreeethat there are better and more expensive setups, but for 1/3 of price and for maybe 85% of DASA power output , this BB kit from group K surely sounds nice. Obvoisuly, as we say, "paper will accept anything" - it is the matter of direct comparison on water....

I don't know about 1/3 less, if you price out everything you have to buy for the Group K motor your getting up there close to a Billet BB. I started getting all the stock parts to build this package, it sounds cheap at first.
I went with another package for just a little $$.
