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.

It might make life easier on you to run a carb and vacuum advance distributor. I'm not overly familiar with the injection setup on the engine you have. If you want to keep the EFI you'll need a higher pressure fuel pump, return lines to the tank, all of the electronics from the donor vehicle, etc.

FYI your casting number on the Mortec site gives the following info:

10243880...350...95-00...2 or 4 main bolt...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal

The main reason for the swap is the TBI, FI is is almost a necessity off road, there are times when my vehicle is almost vertical, the carbs don't cut it then. I am well aware of what needs to be changes to get the SBC in the jeep, its almost done and about as easy a swap as you could do. but is there anything that i would want to up grade to sneak a bit more performance out of it. i have to replace the TBI unit, should i stay with the stock unit or upgrade it?

At the very least I would upgrade to the holley tbi unit for the bigger bores and a better intake. The intake design on the tbi is horrible.
