Hello everyone. Picked up an 87 gmc crew cab but it came with a 427 on a stand. Tall deck. Holley double pumper but the truck should have had a 454 Tbi. Probably a stupid question but can I mount the tbi carb on the tall deck or do I need a lot more?

The TBI should bolt to a factory intake using the factory adapter. A number of companies make TBI to 4bbl intake adapters and they will work also.

You can buy intake manifold spacers to use a car / pickup manifold on a truck engine.
