This is my first post. I've been reading the site for over a year and it's been a wealth of knowledge. I finally decided to purchase a Superformance Cobra. I've made my engine choice to be a Roush 427 SR-TW with the TKO 600 transmission. What I'm trying to figure out if anyone out there has switched from the Roush carburetor to a Prosystems carburetor and if there were any benefits/gains to be seen (street-ability, performance etc). If you did use the Prosystems carb, which one did you use?
I've read several threads regarding Superformance headers and sidepipes and their restrictions and them not being the greatest quality. Looks like they've made some improvements, but I'm not sure how much? Should I look into a better/less restrictive header and side pipe? I was looking at Firefly Performance. Any thoughts?
I'd like to get it right from the start...
