Hey guys after doing the cobrajet install on my boss 302 i am having trouble shifting at redline. Thats the stock redline i never raised it and i never had an issue before the cobrajet manifold. I have an aftermarket shifter, bracket, trans mount. stock clutch line and clutch spring still in. I've searched around and i haven't found any threads with solid answers other then replacing the clutch. Is their an easier definite fix? clutch line? spring removal?
