serious street power.

yah my thing is i dont want to have to kill the motor to run 12 second 1/4 times and it needs to get new pistons...rings...bearings and get machined anyway... since ill be getting my tax return around the time the motor gets done i figure stroke it to 512 for big easy power and then maby later on update the cam as well and then it can be street friendly in at least low 12's. i will still do all the fine tunings and tricks to get it going faster but im tired of that being all i got to increase times i guess.... nothing like a big block stroker....
Does the stroker kit change sound at all of the motor? kinda like cams?
