Our 347 Street Short Block is a great replacement
for your tired factory motor and can make great power for a light load on
your pocket. The pistons are fine with lower boost levels (under 10psi)
and light nitrous use (no more than 150hp), or are also great for naturally
aspirated street performance motors. This short block is balanced to 28oz
and recommended for most street oriented setups. Don't hesitate to ask us
about custom internal parts for your exact needs, wants, and application!
