You should look at the on3 performance turbo kits affordable and can easily split your block.. Lol.. But yes look into a aftermarket block to build... The 302 Mexican blocks have very strong journals and are a cheap route but getting hard to find.. But build it right so it last.. Get a dart or boss or DSS block if you want twins... And a dam good facility to tune it..
