Have a 305 87' Monte Carlo SS. Bottomline is that i want more power out of it and since im basically really new to cars how should I go about doing it? I've asked my dad if we could put a big block 396 in it and he said we could but then we have to change exhaust and a 100 different things because of the size difference. Whats my best and easiest way to get the hp up without getting into something that i'm obviously not ready to get into.

I'm not trying to get 400 hp out of this car since I want to do this just as a strong driving car that I can take out on weekends and such and get another muscle car to really let loose some power.
