I know tops gotta be replaced is it really hard to replace a top I've been lookin for a t top but when i found this one I had to jump on it never had a vert or t top just hard top. And the guy says it has a 89 formula 350 in it tbi how can I find out if its really a formula 350 or is there anything special with a formula 350 or is just a regular tbi 350 what can I buy to make it tpi any spots that sale the wie harness intake ect...thanks

 

CAll your local chevy dealership and give them your VIN numbers they will tell you everything about your car from the day it was born till now .For a fact this is the best way i found to make this confirmation.
If there haven't been any modifications done to it. that is

 

Sorry i got nothing else for the rest of your question. But im sure some one areound here does. Good Luck in all your third gen endeavors!

 

There's nothing special about it being a Formula 350, that's just the car it was in originally. If it's a later block, 87 up I think, it will have a 5.7 stamped behind the driver side head. Look in the classified adds here or on craigslist for TPI parts. There's a thread with all the info to repin your TBI harness
