LS is now 15 years old--will be old enough to drive this fall----------

as for the 283----with todays parts, you can build a 283(or about any size) sbc with very lite pistons/rods, small bearings,etc and with the heads/valve trains(jesel type shaft rockers) lite wt roller lifters, etc you can build a lot of hp that is very streetable---just don't put it in a four wheel drive suburban!!!!!!!!!!
