budget 273 build

The Torker 2 still has 340 runners.

260 is advertised.

Most small blocks will run best at 35 degrees total advance. If you build a motor with 10.5 compression and have to retard the total advance to 25 because of detonation, a 9.0 compression motor with 35 degrees total advance will make more power. I have seen 10.0 compression motors where the top rings turned into 75 ball bearings. It leaves an impression. If you want to try and play with dynamic compression to get your compression down, that is another can of worms. Just remember, you only have 273 cubic inches, a bigger cam is not street friendly. You want to build as much torque and mid range as you can. It should rev to 6,000 rpm easily.
