Just keep the hood closed.......Heck, I almost put a carbed Mazda 2.0 MA w/5sp in my roller 65 Barracuda when the motor was out. Only thing that stopped me was no clutch pedal in my 65. ~Same HP as the slant.....half the torque. Truck weighed 500 less than the 65.
Honestly the sound is what usually makes people ask “what the hell is in that thing?” It really does sound much different than the usual small block or straight 6.
