Hang in there and someone will get you an answer. I have not been around the Hookers. Both Flowmasters and tube style DynoMax have been used on mine so they will be OK.
You may have to get the tape measure out if there is a certain brand that must be used.
I sure like the Flowmaster 50 series Deltaflows. Not cheap but sound good on my 302, and there is noticably better power than the glass packs I had on there before. If money is an issue, then turbos from Kragen, etc. might be a good idea. They sound good, too, but won't give you quite the torque. Blue Flame glass packs sond nice too, but glass packs won't give you the power either, and they done last too long -- mine went about five years. However they sound nice and are not too expensive. Kinda depends on how much you want to spend and what your sound and power goals are. Don't forget the cross tube no matter what you do; better torque and smoother sound.....
