new 5.7 1987-1996?

[Scott06]

I run this on my 5.0 vortec https://www.michiganmotorz.com/5-7l-4-bbl-vortec-cast-iron-intake-manifold-1996-current
Came with the partial engine I got from them- has a very nice mid range punch works very well idle to 5k rpm

You'll probably have no problems, but I like the one Scott posted from Michigan Motors myself,.....
