the cheapest set I found was $149us that uses global shipping so still cheaper than summit racing and their sets don't include rings.
What about http://www.ebay.com/itm/321501225923?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITAlso read the add with ones saying they are STD quite often near the bottom of the add/description some tell you what over sizes are available and it's just a matter of leaving a note on the purchase order.
Ok that's good then that the rods don't have to be bushed, I take the big ends are fine and just require the correct size bearing to bolt straight onto crank journals including mains (no line boring required) yes mine pulls right off idle right upto max rpm with no hesitation or flat spots and plugs look pretty good colour considering it's a bit rich but the rollers adjusted it to a happy medium if he leaned off topend then bottom and mid were lean so he went for richer top end as it wouldn't be there all the time, maybe mine would make over 200 if it was leaner top end but then bottom and mid would suffer, often think about going to carb as jetting it would give a better fuel ratio throughout, I don't have the knowhow and patience to be experimenting with the k jet as you
Yes the big ends and mains on the 4.0L crank are the same dimensions as the 2.8.
Without seeing your actual fuel curve it's hard to say at what stage your motor starts to over fuel. But I'd say it's a pretty safe bet that it would break the 200HP mark by leaning off the top end. If you can do it without leaning the bottom end as well.
By the way Very impressive power @ the wheels Stroker especially as it's 4WD
also did you get the crank assembly fully balanced once bells and nose were machined down and if you did did you have to have weight added to the flywheel and front pulley?
Yes you have to add weight to both the flywheel and the front pulley. I had a steel flywheel made with counterweight for mine, but you can just have a piece of steel machined and bolted to the flywheel and front pulley.
My front pulley is similar to the image I PM-ed you.
