If your running this block what is the most power you made and what modifactions did you have to make to make to hold it? What heads, what pistons/rods/crank, ring gap, spark, plug gap, etc. Just curious to see what a stock block can hold.

I've read 1200 on the stock block keeping it reliable. Of corse people push it more then that.

I made 740whp with a totally stock 2001 LQ4 engine (weaker rods). Some have done a 1000whp on stock shortblock. If you run Methanol and fill the block, guys have done over 1500hp (all best parts money can buy with stock block.). Your limits ultimately will be the 4bolt head design and the webbing around the crank.

With four bolts i understand that is a limiting factor but what about half inch studs? Basically estimate the level the webbing gives out?
