helping a friend put a 5.3 liter ls engine from a 2000 chevy silverado 1500 series. it will be going into an 87 trans am gta

what alternator will we need? the engine he bought didnt have 1 with it
what oil pan will we need? the truck 1 wont clear
what transmission crossmember will we need?


we have everything else except that stuff does anyone know what we will need?

 

the Silverado alternator is just fine. You need the '98-'02 LS1 F-car oil pan.
trans crossmember depends on which trans. If you're going 4L60e, then a 700R-4 crossmember will work perfectly. If you're going T56, then IDK.

 

that was fast. thanks

what power do you think the engine will produce with a ligenfelter gt2-3 cam in it? i cant really find much about it

 

oh yeah and will any other oil pans fit the ls1 engine if its just a regular chevy oil pan?

 

answered in your other thread

you will also be better off getting an LS1/LS6 intake, f-body accessory mounts and use f-body accessories, plus swap mounts.

 

Nope, the trans mount for 4L60E is moved 2" back from the 700R4/4L60 position. Modifying the stock crossmember to work isnt hard, just dont expect it to bolt right in

Be aware the harness must be built around what alt you are using. Fbodys used a 1 wire alt, early LSx trucks 2 wires, later LSx trucks and vettes used a 3 wire alt. None are compatible without the related wiring

Be aware the only part of the 5.3L engine you can really use is the longblock. All the accessories, intake, pan, exhaust etc will not fit. You need Fbody parts to make it fit best. Some C5 stuff will fit ok, but the cost is higher

 

That can't be right, unless you're using a later 60E with the 6-bolt tailhousing, but those suck. Those have a removable bellhousing.

 

yeah we got the ls1 intake from fbody alot of the parts r fbody but were using the alternator from the truck. will there be any hood clearance issure? cus i hear guys say there good slams onto the alternator

 

also how bout the fuel line? can we use all the old fuel stuff? hes getting a high volume fuel pump and has the fuel filter with built in regulator. will all this work with the stock tpi fuel lines?

 

You need the Fbody accessories. Fbodies mount the alt low on the drivers side. Trucks mount it up high above the hood line

Stock fuel lines can be modified to support the LSx engine, but its easier to run new SS lines from the tank forward. Diagrams with PNs are posted in the sticky

 

oh ok thanks.

1 of my friends is parting out his 84 camaro berlinetta.

how much do u think he could get for the digital dash and the zebra print interior. its all in perfect shape except driver side seat is ripped and the dash pad on tip on driver side has a piece busted off.. barely noticable
