installing a 1989 350 in my 72 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hey everone, i purchased a 1989 chevrolet van with a TBI 350 that just had the upper end re-built. I am planning on doing a swap this weekend. My truck is set up for a 4-barrel and I know what is involved in changing over the intake. My question is, how hard would it be to convert my truck to run with the TBI ? What modifications have to be made ? Are there any advantages if i ran the 350 as TBI as opposed to using my 4-barrel. Which is better? Is one more powerful, better fuel economey ? thanks everyone. I need to be decided by saturday !

also what rear-end gears are in the 89 van ? it's supposed to be heavy duty... would the gears be better than the stock gears in my 72 half ton ?
