Well judging by the exhaust peeking through it at least has the 305 in it. Most likely carbed. I believe the HP rating for that engine was in the 170 area.
EDIT: Found them! Its a pic of a pic but its quick and gets the job done:

I paid 800 for the car, It has a red door and fender so I had the enitre right side painted for like 350, then over the months fixed her up on my own. I had a freind cut the "Formula" decals for me and restripe the passenger side. I did the hood intake panel painting myself(original idea BTW) For some reason it had firebird wheels on it..I found a set of true Formula wheels and traded the crappy 15's for them plus 100 bcuks boot and refinished them myself. Also restored the interior and thanks to my new friend at the time(ebay) did the underhood area. It was a slick car. I had a lot of fun and good memories fixing that car up, and it really served me well. Everything worked and ran flawlessly. The guy I sold it to wrecked in in the first week :cry:
