Intake Manifold issue

Hello,

We are doing a 350 swap on my car however the 350 came from a carb'd car. I am going to be sticking with the TBI setup as I am more familliar with tuning a TBI than messing with a carb.

The problem is. The intake manifold off of my 305 TBI will not bolt to the 350 block. The intake manifold for the 305 has angled bolts that bolt to the heads where the 350's manifold mounts are right into the block. Is there something I can do to rectify this? Looking for a cheap solution. Let me know

Oval the holes on the manifold.

Yes it will. It just doesn't line up to the heads.

Like said, elongate the intake bolt holes. The center two on each side.

Re: Intake Manifold issue

Keep it carb'd man... Pop a four barrel on there and it beats a TBI setup any day. It's probably more simple than TBI, too, especially since it's already on the motor.
