This aluminum head from Trick Flow produced 496 lb-ft of torque at 4,000 rpm and 455 horses at 5,300 rpm. With its 195cc intake ports and 215-cfm flow numbers at 0.400-inch lift it was a good match for our 383 small-block test engine. Matched to a similar engine, you can have neck-snapping torque and big power. We went over our budget by $26, but at such a marginal cost, who are we to not test them? Besides, a week of brown-bagging our lunches made up the difference.
