I have a 78 El Camino with an Edelbrock Performer and 4bbl on a 350. I am considering options for a new or rebuilt engine that I can drop in. Will this manifold fit the later small block engines, say '87 and later that started coming out with TBI? I see quite a few of these with low miles for sale, but I do not have all the TBI equipment figured out yet.

Thanks

Should, but you may have to modify the center four bolts b/c wasn't it '86 when Chevy changed their angles slightly but left the rest of them alone like they were??

And the Vortec has straight up bolts like the 302 Pony-car engine has. Totally different..

Dont know about any angle changes, but I've got a 72 350 with Vortec heads on it in the garage and a RPM air gap fit perfect. I think your intake will fit fine on a 87 350.

As Paul stated, you will need to modify the center 4 bolt holes for the 86 up heads. They are in the same place, just a slightly different angle.

The 96=99 Vortec is a completly different head & intake.
