Hello to anyone seeing this, I currently have an 1973 chevelle laguna that I am pulling the motor from, it is a sbc 350. I am not too interested in restoring the laguna(its too far gone) but I do want to rebuild the motor. I am looking to maybe up its diplacement, but definitely looking to get upwards of 300+hp. I dont have pictures nor all the information right now but I will sometime soon. Any advice or stuff to put me in the right direction is much appreciated. Have a good one!
