I have a 90 tbi... not sure if its a 305 or 350... i believe its a 305 bc it has a 3990 oil filter in the middle of the drive side of the block..

WELL, my question is what is the difference in taking a long block from a 96-2000 truck and adding my 1990 tbi intake man w/ distributor etc. does it have a different firing order that i'm unaware off for a 350?

Thanks in advance

The intake bolts for a vortec that was made from 96-2001 is a 8 bolt pattern and has no center bolts where the TB is on a older model. The bolts are also straight up and down. I have seen a TBI intake for vortec heads once upon a time when I was into the old SBC GEN I engines. They are fantastic heads for the dollar. There are also adapter plates for a 4 barrel intake to use a TBI as well.
