Just got myself a 68 Barracuda Fastback!

Hey everyone! I bought a 68 barracuda several weeks ago for as my new project. The car has very little surface rust and only a little bondo as far as I can tell. Right now there's a 318 in it backed by a 904 and 8 3/4. I have an a833 that I'm swapping in and wanted your opinions on whether I should do a 408 stroker or a gen 3 hemi swap. ditching the 4 speed isn't an option so I was wondering cost/power wise, which one you guys recommend. Ive heard of people using an a833 behind a hemi but I already have the stock linkage and bell housing and not willing to get rid of any of it. I talked to an engine builder near me and he quoted me 4-4.5k for a 450 hp 408. So that is my limit currently. Any tips and advice is appreciated. Thanks in advance!
