I think I would run cobra forged crank, manley rods, and manley, ross, or diamond pistons.
you could also call companies like MPH, DSS, steen, foxlake, VT and get their take on all of it.
some of the companies make thier own rods and cranks.
have you priced out just buying a complete short block vs machining the stock block and building it?

I kept the stock crank since it good enough for all but the most serious horsepower or high RPM applications and added Diamond Pistons and Manley rods. Good for 600hp.

I am in the process of doing the same thing. I just got a romeo short block out of a tbird and getting ready to send the block to the machine shop. Just out of curiosity, how much did you pay to rebalance the crankhaft?
From what I understand, there is no need to rebalance the crank shaft. The rods and pistons are what need to be balanced to one and other with a modular assembly and since I bought them as a kit, it was already done for me. Apparently, the only time the crank needs to be balanced is with a stroker set up.jstreet0204 said:

thats what I did also... like he said good till 600 and I dont plan on going far over 500
I have a stroker crank (Cobra i believe), Manley Platinum Series Forged Pistons, Manley Stroker Forged I Beam Rods. All from the Infamous Seanhyland Motorsports. Everything is great for me so far except I don't know what clutch and flywheel to buy for the 8 bolt crank.

They don't have an option with the cast cranks, so their cheapest rotating assembly is 1900 plus you have to add $200 extra for balancing.

Mike get the Spec stage 3+ clutch and lightweight flywheel. The clutch is suppose to be as streetable as the stage 2 but have the holding power of the stage 5.
And as for the rotating assembly yes it is $200 extra but you have to have the stock crank rebalenced anyway. May as well start out with a brand new one and have the ability to wind it past 7000 RPM. The stock crank is not save past 6500 RPM.
It is your money in the end might as well spend it wisely.
