Big Block Vs Small Block Chevy Comparison Youtube
Wikipedia says 255 HP, 290 ft lbs of torque on the Vortec 305 so its torque is shy of the 57, but HP is the same Even if those numbers are inflated, a TBI 350 was only good for about 2 horsepower A lot of people say they are dogs, but all things the same between two trucks in a blind test I bet they wouldn't notice the difference Also, a quick view of the balancer will give a general idea of what it may be The 307 uses the 327 small thin (maybe a inch or a little wider) dampener where as the 350 uses the wider dampener Doesn't mean it can't be a 305 but the 305 dampener is also different It takes a few ID sessions to get them all down
