Back on the dyno, we immediately noticed an improved growl. The horsepower jumped to 146 and torque spiraled to 222 lb-ft. It was a 22-percent torque gain throughout the curve with all the power in the game by 4,000 rpm. The lowly 305 was only off Jake's 350ci base numbers by 22 hp and 7 lb-ft. The backpressure reading had also shrunk to 2 psi. Not too bad. What Do You Want Us To Do With Cone Head?OK, so we'll admit we're maybe a little too giddy about 146 hp. The point is, with a little effort we got a big gain in performance and appearance, albeit on a smaller scale than a typical musclecar. We want to know what you think about Cone Head and what you want us to do from here. Is it full-on LS series swap with a 4L65-E? Or should we leave the 305 in there and try all the speed tricks we can think of? Should we drop it in a canyon? Let us in on it at carcraft.com. We're lurking there.
