Just landed a set of Headers for the 90
I just got a set of used Waston's for the 90. Thinking it would be neat to dyno the car now....i already know the car runs a 12.88 @ 112.68
Then add the plenum...Dyno and run at the track Then the headers........dyno and run at the track This would make an interesting article. Also thought a porter shootout would be fun.....try different manifold porting on the same car to see if there is a power difference. Locobob, Jeffvette, Pete, Haibeck and maybe add a "carbide cowboy" and see the difference  Siamese vs standard porting....rough plenum vs smooth, etc
