    Question '83 chevy 305 mods for better hp

     



    Hey Guys!
    I'm totally new to this kind of thing, but from what i read on this forum, a 305 should not produce as much hp as a 350 because the pistons are smaller, producing less compression???

    What about if i change the heads and end up with a tighter fit, would that work?

    I went to some other website and they were experimenting with bolt-on, off the shelf parts and they ended up with more than 350hp and even more torque...not bad!

    What is the bad rap for?

    Anyone did a project with this motor and got good results?

    Thanks!

    Ps. Please no BS! I want infos. If your ego needs a boost, go flame someone else

    This has been gone over and over many times. My 305 was bored .060 over to 315, new flat top pistons, new cam extreme energy cam XE262H-10 218-224 Dur. .050 .462-.469 Lift, new headers, new edelbrock intake and 600 cfm carb, new valve springs, lifters. Puts out close to 300HP and 308 torque.
