No, they're 2 different hood designs
It will fit, but ti being a tall deck block will complicate fitment. You will need a taller hood, and a regular L-88 or big block style will not fit. You will need custom fit headers and a 4" or 6" cowl hood.
It sure will but you will need to probably put a cowl induction hood on it so it will not have any hood clearance problems. I have seen a few I think there is a small space problem with the HEI distributer. Not a big deal... just a tight fit
the engine will fit , but you have to either fabricate or buy some custom mounts, and you wont get to use your hood anymore. the engine is too tall and sticks up out of the bay. i just got a cowl hood for mine,
99 ?
Short answer is no. The '64 was one year only, came to a point at the grill that was integrated into the shape of the hood. '65 hood will fit '66 and '67.
yes
yes the hood mounts the same way
no
No.
2003 - 2004 will interchange.
The hoods from any fifth generation El Camino will fit. This includes flat and cowl induction styles. I believe you can also use a hood from a Chevrolet Monte Carlo and a hood from an Oldsmobile Cutlass from similar years. There are also many aftermarket styles available that are made specifically for fifth generation El Caminos.
