I have a Buick 350 originally out of a 72 or 73 Skylark or similar car. It is stock with a 2 barrel. I wish to perform a complete overhaul and am needing some advice on upgrades. This engine is in an old Ford pick-up and will be used for street-rod use... so low RPM drivability is important. I do not want a poor idle or high stall converter. Horsepower? All I can get with-out sacrificing street cruising. 1. Would using the 10:1 compression cast pistons be safe with pump gas or should I choose a lower ratio? 2. I would like to use a hydraulic roller cam & lifters, but don't know which grind specifications to choose. 3. Fuel delivery... carb or throttle body fuel injection? 4. Duel plane or single plane manifold? 5. I have been waiting for the aluminum heads, but may go ahead and order the cast iron heads from TA and revisit in the future when the new heads are released. 6. How much difference in HP can I expect from TAs $1000 roller rocker shaft? Thank you for your input!
