With these lovely old V6s, they have rock solid bottom ends which last and last if you keep the oil to them and don't spend much time revving their titties off. The big let down is the heads which are 'slow' and heavy as heck.
My suggestion is to get a nice old grandpa motor, put some flowing after market heads on it, chip it, cam it, pipe it, dump it, look after it and give it hell.
My guess is alot of you guys on here are not quite old enuf to remember what a street full of cammed-up cars is like, but it fricking rocks.
And with fuel injection and engine management systems, they don't have to be so undrivable as a carb'ed beasty.
