Any ideas why it is so cheap? Does this seem like a decent deal? Also does anyone know if on those pistons the wrist pin intersects the oil land which would cause it to burn oil?

Thanks

My thoughts are that you always get what you pay for. A 3.25 stroke and a 5.315 rod will require a piston that will be far from having oil ring to wrist pin issues. Speaking of which, I've seen Keith Black pistons first hand and was very un-impressed with them. All and all, I wouldn't go for it personally.

The light weight forged I beam rods leads me to believe that they're forged aluminum (I could be wrong, it's not specified) but if that's the case then they're no good for a daily driver.

The bottom end on your motor is nothing to be cheap about. Especially for a daily driver. I am personally going with a 347 kit from eagle. Thats because I know a few people that have it and they haven't had one problem. Yet at least.

To go the cheap rout but still get good parts. You can get the eagle 331 kit with a non-forged crank. And thats for exactly a grand. The forged crank jumps the price to $1400.

If you are going to be upgrading blocks then get the forged crank. If your going to be using the stock block. You will only need the cast (non forged) crank. You will crack the block before that crank goes.

Over time (relatively short when compared with forged steel or even cast), aluminum rods change shape (bend, twist, stretch, etc.). They're fine for a race application where the engines cycles are few and far between or when the motor is started, run like mad and shut down but they're not designed for the stop and start driving associated with street use. Of course this is all assuming that the rods in the kit you posted are in fact aluminum.

More bad news on this kit

"I believe that rotating assembly is CAT. Hence the reason it is so cheap.

I have seen issues ranging from journals being way out of round, unparallel, counterweights too big causing interference with the block etc etc, and I hear they can be a major b**ch to balance.
I would stay away from that kit."

That was from a different site... sigh why do they sell it if its such garbage?

I'd pass on the Egay specials. Stick with GOOD parts. My 347 rotating assembly is all good parts. Scat cast steel crank, probe srs forged pistons, probe 4340 forged steel ultra light I beam rods, perfect circle rings and I thinin clevete bearings. If I were buying a rotating assembly (my builder ordered mine for me and I picked the parts) i'd order from www.adperformance.com The basic scat 9000 kit for like $1000 will probably handle double what your stock block can I upgraded to better/lighter rods though. It does not matter if the pin intersects the oil ring or not. If your afrid of that, just use the 5.315" rods from probe. I actually use those rods but NOT because i'm afraid of a myth. I got them because the 5.4" rods I wanted were on some insane backorder.
