Can I compete in TS with 3.55's?

Maybe so on a N/A motor Joe, but start force feeding it with a blower and the aluminum heads will win hands down. The aluminum heads dissipate the heat quicker which will prevent that nasty pre-ignition once you start dumping massive amount of air & fuel into the cylinder. As someone else already pointed out, you also need a greater exhaust/intake ratio with the blower car to promote good scavenging of all that mixture. The aluminums also help the high compression motors for the same heat dissipating reasons. Same theory as going to colder plugs at higher compressions.
