----I take it you like these ram-air manifolds as much as I do. When restoring my 69 GP/SJ 428/370 I couldn't bring myself to schlep the log manifolds back on the car. Those have to be the most restrictive exhaust manifolds known to man!!! Along with some other judicious modifications that no one will ever see, I thing I am well beyond the 390 rated 428/HO Grand Prix top engine option......Bill S
