66 SS hood

Is there a part number on a original SS hood? Looking to buy a original hood but need to know what to look for to make sure its not a repop. Thanks

Re: 66 SS hood

no part number. there was three designs of the hood and the repro follows the third one. the easiest way is on the front edge. by looking on the side originals has a lip about 3/16 where repro does not

Re: 66 SS hood

I'm aware of two designs. First is part number 3874746 for the early hoods with 5 cutouts on the underside prior to Jan 20. Second design hood is part number 3896559 with 3 cutouts on the underside. Some plants may have gotten the later style hood earlier than Jan 20 and some may still have had inventory of the early hoods

Re: 66 SS hood

Dale I recall from way back when Mike Crown showed a 1st design hood that had the hood louvers bolted down directly to the top of the hood skin. for the second design they recessed them.

Re: 66 SS hood

You are correct, Keith. Blue is early, red is late.

Not aware of a third design but the same two underhood designs were applied to the other 2 hoods, one for 300/300 Deluxe and one for the Malibu.

Re: 66 SS hood

If I may.....I believe Keith is thinking the first design was the 5 cutouts with non-recessed louvers, the second design had the recessed louvers and still had 5 cutouts, while a third design had the recessed louvers and 3 cutouts. that's always been my assumption, but hadn't ever researched it.

Re: 66 SS hood

There were only two versions:

1. The 5-hole with holes for mounting the scoops (which holes apparently were a little smaller in measurement and a little shallower than the second design, which made the scoops stick up a little higher and made the indention in the hood skin less visible under the outer edge of the scoop); and

2. The 3-hole with holes for mounting the scoops (which holes apparently were a little larger in measurement and a little deeper than the first design, which allowed the scoop to sit "down" in the indention in the skin and resulted in the visible groove all the way around the scoop).

There was never a factory 66 SS hood with scoops mounted straight on top of a flat Malibu hood without scoop opening holes. Period. See the second link in Dave's post above for more details!

When I was much younger, I mounted a set of SS scoops on a Malibu hood... I HAD to cut large rectangular holes in the hood, because the scoops actually protruded below the hood skin, so they would NOT sit on top of a Malibu hood... I also had to grind a small ridge (gasket retention?) around the bottom of each scoop... But with a limited budget, some extra scoops and a spare Malibu hood, I took on the challenge...

My other real SS hood at the time must have been "early", because the scoops were not recessed.

Once you go RAT, you never go back...
