it doesn't say with or without the insulation but the insulation is 1lbs
81-88 Cutlass Factory Component Weights:
Aluminum Steel
Hood 22.5 lbs 53 lbs
Thanks Steve.
If those numbers are comparable with the '78-'80 hoods, that's great news for me as my highly modified scratch built hood currently weighs in at 52 lbs.
A pound actually lighter than what's listed!
That's possible due to the large amount of factory hood bracing and hood catch I cut out of the underside to create clearance for the 455.
Mind you, that 52 lbs is with the hood still in it's raw unfinished form, without body filler, seam sealer, primer and paint, hood pin plates etc.
I'm thinking by the time it's totally finished out, it should be about bang on or still slightly lighter than a factory steel hood.
I did do a Google search before I posted, but came up with nothing for the '78-'80 models except weights for lightweight fibreglass race parts.
I'd still be interested in hearing from anyone that has weighed or knows the weight of steel '78-'80 Cutlass hoods...
