Oops, GM 5.0L and 5.7L intakes are they the same?

I'm putting a 1995 donor 5.7L back together (in its factory configuration) and putting it into my '87 Chevy P/U I ditched the original 305 except for the intake set up. I didn't label either intake, but seem to think the 5.7L used the intake with casting #'s W2, 14102182, 6248. The other intake has a W6, 10166133, 5296 numbers cast in. Both intakes look identical as do the throttle bodies. (Same bore sizes)

Does anyone know if either of these are 5.7 specific? (I had originally planned on building this motor up, but with the recent economy she's going back together as is....for now)

Thanks in advance.

I believe its the internals crank,bore stroke etc. thats different,not the intake manifod. I beleive you can use either intake,but Im no expert like others on here,I could be wrong.

They are different intakes, but they are interchangable. I would use the ones that most closely match the ports on the head (just measure width and height) and the one that is the tallest. That would theoretically flow more and be a better match for the 5.7. Since they're both factory castings, they'll both be mild-flowing intakes, and unless you've souped up the rest of the engine, either one should be fine.

I never thought to compare the height or port sizes.
The motor isnt hopped up at all at this point. Maybe a mild cam later. If I change the intake later, it will be with a pair of vortec heads anyway.

Thanks

I should add...

The throttle bodies are the same, but the injectors are different between 5.0 and 5.7. Make sure you have the right injectors.
