im new to this and oviously no person needs any logic to infer that a 350 will always make more power than a 305...yeah more power when were talking 700 hp...a 305 can make 300 - 400 hp which is perfect for a steet car or truck...this isnt a track car.... the 350 might save you 100 maybe 200 dollars, even if the 350 block is 400 dollars that still dosent compare to the perfect condition 305 i got for free...look at this http://www.goingfaster.com/spo/325_h...chevrolet.html
