i have an 91 silverado with a 350 in it..i sold the motor to my dad for his 85,n though the moter i got from him was a 350 4 bolt n it wasnt so i figured i would go, LS! what would all i need to make it work n be able to tune it like my 06 silverado..

 

So an LS in your truck?

-Motor mount adapters
-Fuel rail adapters
-Stock computer and wiring harness
-LT1 flexplate
-Radiator hoses

Its easier if you can get the engine and trans from the LS truck, making the 700r4 work with the new engine isnt a good idea IMO.

 

damn the 700r4 just got rebuilt like 2yrs ago:/ how hard would it be to put the 80e in it ?

 

Im still workin on my swap but i think to drop the 80e in u hav to lower the crossmember an inch or two and be good...could be way off...i do know that as far as parts go atomic has the parts u need already listed...But no way would i go with nething less than a 4l80 but we are shooting for 700hp so if its just a daily driver then u could go with a newer style 4l60 if u plan to stay stock...oh and u will need a walbro (depends on what u plan to do) or a 96 or newer fuel pump for a silverado or sierra, lokar adjustable throttle cable, and corvette fuel filter 99-04...u can use the stock exhaust manifolds or switch over to shoenfield longtubes...is it a rcsb or ecsb?

 

well i was thinking of makeing to all out drag street truck out of it....so yeah i would love to have the 80e in it..its what im puting in my 06 soon..im just looking for an cheap 5.3 for now to get it all fited n get it running right n when i get the real money for a bigger motor...nos n other stuff going in an so is a roll cage everthingtaken off that i dont neeed like AC,wipers,smog ****...just the junk that u dont need on the track...but i just need to know what all theres to get to get running,so i can get my 6.0 for my 06n finish th 06 silverado up n buy my 408 n 250 shot..hopfully thats them dream trying to stick with it

 

I have a stock 5.3 for sale, 70k miles...

Not sure what is needed to put an 80e in an OBS, but im sure the crossmember will have to be modified and custom driveshaft....which you should get anyway if you are making decent power.

 

how much?!
