little 'ol 273

I have a 273 in my Valiant, all I did was bolt on a set of magnum heads and put a 455 cam in it, and since it has 1.6 rockers, it made it bigger yet, 4.85 ish if I remember right. Aluminum intake, 600 eddy, and I ran the magnum exhaust manifolds to keep it simple, the thing runs real good, and it was cheap. I just re ringed it along with new bearings, thats all.
I notched the cylinders for the valves, magnums have bigger valves. Dont know if it was needed, but did it anyways, cant hurt.
I bet if I had headers it would really run, but I didnt want the hastle and the ground clearance issues.
Love my 273, wouldnt have it any other way.
