i have a 1990 suburban. just need a lil help. I recently got my hands on a 350 for it. the casting #s are 3970010 for the block. this engine is carburated. my suburban is tbi. the intake for the tbi has a different angle on the intake. i found an adapter for the carb intake to make it tbi. is that a good idea. am i going to have any other problems? if anyone can help me i would apperciate it.

 

Some of the adapters work fine. One of them I think it's the Holley one, relocates the front to rear, and makes it hard to fit everything. I think it's the Edelbrock one, fits better.

 

do u think i will have any emissions problems using the older engine or should i be ok

 

Those adapters will raise the TB enought that you might have to modify your throttle cable,TV cable, and fuel lines.

 

but the older engine shouldnt mess with the emissions for the newer vehicle
