273 upgrade intake and cam

SP2P and the Weiand are polar opposites. SP2P is torque, and nothing but (huge advantage on a 273). Weiand is more of a general with the top end emphasis as most aftermarkets are. With the SP2P's small runners and the smaller displacement of the 2bbl 273 and stock logs, Id go that route. If you change the cam and want the power band to come up, then the Weiand would be a better choice. Performers are good too. You may need a plate on that SP2P to seal the carb, that baby is lean all around!
i see what you are saying here, its kind of how i have my slant six set up based towards torque than horsepower. the 273 does need a boost in the low end department. would the sp2p be a noticeable change from the stock two barrel? i just dont want to have basically an aluminum 4 barrel intake that is comparable to the stock 2 barrel. also whats the rpm range on the intake. Thanks for all of your guys knowledge and experience it has truly pointed me in the correct direction
