help with 273

That is what I am afraid of. Build the little motor and then kick myself cause it doesn't satisfy me. Guess I could always build another car and just cruise the 273 car :)

What exhaust is on that 360? Do you use the 273 manifolds or headers? Looks as if the 273 manifold is all that will fit.

Well the 273 had Hooker headers but when I went with the 360 I bought some TTI headers which are a nice set of headers. My 273 heads was shot so I bought a used pair of 318 heads cast number "302" and ran them on the 273 for a little while. Then I grabbed up a short block 360 and put the 318 heads on it and used the intake (Performer) off the 273. I have a higher compression because of the closed chamber 318 heads bolted on the 360. I know it sounds strange to have 318 small port heads on a 360 but the velocity is outrageous. The motor is to be considered a torque monster. I love the throttle response. It starts to fade off around 5500 RPM but she is all in until that point. I might upgrade later to some nicer heads but I'm happy with it right now.
