89 318

Ok today when i was going to install my inspection cover for my trans, the one that came with it didnt fit :cwm10: grr, and while i was under the car i saw the date code woohoo..then i say 89....omg lame :wack: anyways, i was told it was a 318. but i am unsure, its definatly a sb ha thats good to know, at least i know something for sure. anyways i'm not sure if it has 302 heads on it, where should i start for this build a 89 sounds really lame....has low hp written all over it. the 360 is sounding way better, it was built in 75. what do you guys sugest, i'm really short on room, i dont even know if i could install headers i have ps, and the drivers side manifold is very close to hitting, plus the guy before me swaped it to floor shift which i found out was to stop clearnce issues with the colum and he swaped the fork thingy on the steering arm (under the hood) to the other side so it wouldnt hit the manifold.....wow i'm lost now where should i start. now i'm thinking of buying a 4 speed setup from a guy on here, sounds like a good deal, and maybe just making it a driver soon, building the 360, and getting a 4speed. then taking a week off or something and swapping the 360/4 speed in. how does that sound :)
