1978 Trans Am's had both Pontiac 400's and Oldsmobile 403's. The 403's were much more common, and were signified by 6.6 liter tags on the shaker. The 400 shaker stickers said 6.5 liter. Anyway, the 400 would fit, but I doub't the 403 would.

Shovelnose-
My T/A 403 would have beaten you (521hp NOS injected). ;!)~

Take care,
