Good overall power improvement, strong low and mid power with good top end. good choice for intake swap. I used this intake on a 1990 454SS truck, along with a set of shorty headers, 2 steps above the stock cam, and bored my TB out to a 54 mm, creating about a 750 cfm from the stock 620. I am using 373 gear ratio with the original turbo 400 with a shift kit. This combo works very well, excellent burn-out capabilities!!! Its always cool to see a truck do what we usually see cars do!
Product came professionally wrapped and arrived on time! Little disappointed in the make of the intake meaning from factory the smog bolts are little difficult to get to and the space on the back of the intake for the brake booster cable was a little tight. Overall it’s a great product and fit my needs!
