building a 528 for my car. street/strip car, more street than strip. trying to think what size header should i put on it. 2 1/8" is my first choice because of fitting better. but i keep thinking of upgrades down the road, is 2 1/4" that much worse to install? im making the car for manual steering/brakes. not sure on what im going to do with mounts, im open to a nice motor plate but would like to do a stock style mount like a schumaker. a pump gas street car is all this car will ever be but im sure i'll always want to "tinker" with it especially being my first hemi. any input is greatly appreciated folks!
