Hello, i have a 74 mercury montego, yea its a lang yacht but its a nippy car :) i have a holley 4160 fitted, edelbrock aluminium intake manifold and twin exhausts, i want to change the headers, what would be a good set? Would these change the sound as well? Open to suggestions :)
Re: Increase the performance and sound of my 351w???
Hooker headers with about a 2 1/2 - 3" collector and pipes to match. The key to efficiency and added horsepower is free flow through the system. You might even want to consider opening up some more down the road with performance heads. Alot can be done to gain HP and sound without giving up on quality of ride.
Ever notice that there's so many high performance parts available for GM products?
