big block abody manifolds

dont use them restrictive ,especially drivers side manifolds,I had a 440 in a 67 barracuda notchback and gained over 1.5 seconds running fenderwell 1 7/8 tubes with 3.5 collectors, the 67s drivers side was the most restrictive of the 3 years made, buy a set of hooker super comp 2 inch tubes with 3.5 collectors if you want good flow, that bowed in drivers side is garbage, I have 1968 big block A body k-frame,the type mount that bolts to the front of the engine but after gettin the fender wells I just sold the manifolds, dumb move ? yes ,as I had all the original parts that folks want today,never look back, its too depressing........
