Alright, my friend is selling me a 351 W with edelbrock perf rpm's a pretty mild cam. I will probably be putting on the Trick flow R series manifold or maybe going with the CHP spyder manifold. Not sure which one is better yet(lack of research). He is running 30lb squirters on it, but has never had it tuned. I am wondering if the 30's are a little too big. In the car that it is in it has gone 13.0's at the 5800 ft. Has anyone else used the spyder mani, if so how do you guys like it, if not what other manifolds are good for the 351 EFI.
