Low maintenance and pump gas are the main reasons i built another shortblock. Any 511 in an A body will be a handful.


If you want low maintenance then go with a hyd roller rather than a solid roller. You'll give up some power above 6000 rpm but you most likely aren't going to take a 511 in an A body to redline very often anyway. I run hyd rollers in both of my cars for the same reason.
The way the car is now it never sees the street. Its a 446 race gas only set up 590 cam so its not ideal for street driving. Best et 10.82 best mph 126.0.
