So I guess the answer is NO on getting the 400 SBC.
Now, back to the LT1. I don't think I will rebuild the block until I have problems with it. However, I do want to be a solid 11 sec car. I also want to do it without having to spray 180 shot. Even though that would do it. 12.4 now + another 80 of N2O should make 11s no problem. Things I haven't done to my car are cutout, electric water pump, larger throttle body. Any comments?
But, so I know. Do I need to go 4 bolt?
