You could put money into a 305 or 350. Or you could swap to a iron ls for a little bit more money than putting some bolt ons on those gen 1’s and have a MUCH better starting point. Pretty easy to get 450 hp naturally from a lm7 5.3 and even more from an lq4 6.0. Easy and with a mostly reasonable price tag. As the saying goes “speed is money, how fast would you like to go?”
