The 350 would be a huge step up from the 283, and would actually be less expensive to build HP with than a 283.
My "sediments" exactly. You can't beat the 350 Chevy for an economical build. In a light car such as this, a mild cam, dual plane alum. intake and a slight bump in compression (up to 9.0:1) will provide plenty of get up and go while at the same time, being very reliable.
