318/360 heads,with thumper cam

If you can,keep it running.You stay interested that way.If lo bucking it,a Magnum is a good choice.The truck Magnums are the same long block as the 380 horse crate motor.The cam and valvesprings are the only difference.Hit the yards when you have coin.As for Chevy rats,I grew up on those.Hard to beat, and break on a budget. Good luck.
