what to upgrade on a 5.7

Great forum guys.

I am in the process of swapping a 4 bolt main SBC 5.7 TBI into my jeep. The casting number on the block is 10243880, don't know if it means anything.

Since i really don't know anything about Chevy's, don't know if i should upgrade anything to squeeze some more performance out of it

For example, i damaged the tBI unit pulling the engine out of the donor van. Should i replace it with a upgraded unit or just a stock one. i am not looking for all out H.P., i am more concerned with low end torque and dependability. The engine is a low mile long block that was put in the donor van around 2002.

It is completely stock and will be running ram horn manifolds to 2 1/4" pipes to then to a 2 1/2" single exhaust.
