Im Stumpd

There's a thread on the Spitfire install: http://www.forabodiesonly.com/mopar/showthread.php?t=44321
and somewhere within the thread someone mentioned they thought it was a 30 HP gain over early A stock manifolds. Don't know how true that statement is. From the pictures provided on that thread I can't see where on the driver's side there's any interference with the steering column tube. Now if you have PS, don't think they'll fit.
