Question... How far can I take this block before it cracks??? Currently the car is running low 10's, on a 300 shot. I want to take it deep into the 9's.... It's in a 3600lb 76 Camaro. It has no fill in it.... Is it gonna break? Thanks... :D

How much would filling it to the freeze plugs help???

Is this a street engine? I'd fill it to the bottom of the waterpump holes....

I think I'm going to build a new engine with a Little M block... How much HP will a little M handle before compromising??? Thanks Chris! :D
