I am planning to go with the ram air setup. Mostly for coolness factor. Bringing in cool air is also somewhat beneficial.
Heh Bob, If your opening them up for the RAM air setup then IMO blow holes in those puppies and let the air in! RAM Air setup is very cool and it does add value to your car. They found the location of the scope are wrong in that at higher speeds it tends to draw air out as opposed to in. That's why you see the formula hood on the 69 TA hood with the scoops at the very front. Real facing shakers eventually become the norm.
I spent the wad on my 389 TriPower engine (for my 65 Pontiac) just because of the triple 2 bbr battleship. Nothing else like it.
IMO, if you keep the car stock bu you want more accessories etc. just find other stock components to add to your car without it requiring irreversible changes.
I am going to add the following additional STOCK options: - tilt steering - console clock - cruise control - power brakes - 67 Tall type Hood tach - fold down rear seat - seat extenders (from Bill Edmunds) - '72 Pontiac overflow tank - NOS late 1970's red line bias ply tires (show only) - custom interior seats (I have both std and custom seats) - Remote mirror - RH mirror
