Hi Guys,
Who can recommend a high quality Stinger Hood for my '68?
Please tell me why you recommend one particular brand and for the Aussie CRG guys & gals, let me know who to import it from.
Also, has anyone cut out the opening at the front rather than rely on the cool air induction from the back of the hood? Those ducts are screaming "cut me free!" I reckon.
We don't see many with Stinger hoods down under so I'm wanting to be a bit different.

I always heard growing up that Cheverolet motors didn't like forced air induction. That is why they drew in the cool air from the base of the windshield. Ford motors responded well with the forced air though. Such as the early galaxy, and falcon thunderbolt cars.
Someone may have run a chevy with forced air and had good luck with it.
Now speaking of hoods, while everyone opts to run the 69 "cowl hood" on any first ten, another cool looking hood for a 67 or 68 is the DANA Chevrolet hood. I know there is a guy remaking them from a original hood or the original mold, you just have to look him up. I can look for a pic of the hood, if you aren't familiar with it.
I am not familiar with a good supplier for the stinger hood, sorry.

I think it is just different approaches to the same issue; both approaches are drawing 'higher pressure air', but I'm hypothesizing that the base of the windshield, the higher pressure will be more consistent/stable than the direct forced air?? I've never measured, tested, or studied that.. it's just a gut feel.
Maybe the direct forced air is why Fords 'blow up' more often than Chevys??? :)
PS> After posting the above, I did a quickie search and found someone who had made some measurements comparing 'ram air' vs cowl induction (using an MGB test bed at up to 70 mph). His testing at higher altitude Colorado showed the ram air to provide approximately 50% more 'boost' in pressure than the cowl induction, but of course that would vary depending on the car body shape, windshield angle, etc...

There is zero "ram air" effect below 100mph from a front-opening scoop, as it's in the boundary layer of airflow; that's why the Harwood front-opening scoops on Pro Stock cars are elevated 12" above the hood surface, to get them clear of the nearly-static boundary layer.

When it comes to Camaros, everything has been tried.
Sometimes disatrous results!

Hahaha, I meant the faux opening at the front of the stinger style hood cowl.

He put a stinger on a 69, and was happy with the hood & results

I put a steel stinger hood on my 69 and it fit pretty well. The only issue I had was the "Scoop" area that would normally have an intake vent, did not have proper corners. The metal curved in the bottom corners, as stamping the steel would not allow for a perfect squared out corner. This is where fiberglass can achieve these result that stamped steel cannot.
