my stock LS1 finally gave up the ghost and so i am getting a new shortblock..problem is this..which short block to go with? i already have the following parts..oil pump, pushrods, timing chain, lifters, and the external stuff..but here are the two shortblocks i am lookin at..

SLP 402 iron shortblock-$3600

TSP 347 shortblock-$2700

and that new magic stick 4 cam as well

heads are ported stock LS1
LS6 intake and underdrive pulleys
SLP LT's and loudmouth

i may decide to spray eventually but am looking to make about 500 to the ground NA if not more...question is which block will hold it? and yes my car is a M6 w/ built 10 bolt and 373 gears..the car will be a daily driver cobra slayer w/ some track time here and there..

I'm lookin at the same shortblock... Can't really beat it for the price. I need all the other parts you listed, I have the 6.0L heads, bigger stainless valves and springs. And all the parts that came off the motor that grenaded. Let us know what you decide on, and how you like that TSP 347.
