What length are the K1 rods? I'm in a similar only with the stroker version., I would prefer to put a better crank & rods in the stage2 but if it needs to get built and that's all you have I would use it. Probably better than a BMS crank that's already seen alot of boost.
I have the stock length rods, not the strokers. I would prefer better rods and crank as well, but trying not to go for a second mortgage on this build. I know, it is a Stage motor so it will be expensive, but if a piece is way overkill for a price, I would like to find a lesser expensive piece that fits the bill.
I would trade you a complete set of stage2 heads for the cat crank & cash if you want to get rid of it.
I already have a set of SII en route, but thank you for the offer.
I am by no means an expert so take what I say as just a suggestion. If you are gathering parts to build a stage2 then I'd start with a wide journal crank. Since you will need new rods for an on-center block anyway then they really won't be an added expense. Your crank is stout for a 109 build but I couldn't bring myself to put a narrow journal crank in a healthy stage 2 block. That would be like slapping a set of 8 bolt heads on it. IMO.
Definitely considered the wide journal, but trying to find out what is needed, required, and completely optional in this beastly world of SII’s. I guess that is the reason for my post is to ask what is a good solution; sell the crank and get a different one, use it, etc. Very good input, and will have research even more on where to find SII parts. Having a hard time locating rods, but think TA was the last place I saw who carried narrow or wide journal cranks.
Of course, with the purchase of a new crank, it opens the question on stroke. Should I go with a stroker? Again, having a hard time finding availability of rods, which would aide in making decisions. If stroker rods and pistons are readily available and not made out of unobtainium than maybe I would go that route, if I have to buy a new crank anyhow. The good/bad part is… I already have the crank so it sucks to sell it, then turn around and buy another much more expensive one, but I should be used to that by now with these Buicks!
Where does everyone shop for their SII parts? (ie pistons, rods, cranks, gaskets, oiling, etc)
