going to need new mounts check out dirty dingo for there sbc to ls1 mounts. i have them and love them

and most ls1s are dbc so you would just need a longer throttle cable out of a newer silverado


you are going to have to get the ecu flashed to remove the VATS (security) out of the computer allen can do this and while hes in there get him to do a tune

not trying to thread jack, but do these require the transmission to be moved forward or back at all? im doing a similar swap and trying to avoid re-sizing drive shafts.

i set mine in there so i wouldnt have to make a driveshaft i think my motor mounts are set all the way back im not to sure tho. but yes the factory drive shaft will work with the dirty dingo mounts

How close to the firewall, would all you guys say, your engine is? (I think the rear of the passenger cylinder head/valve cover, would be the closest point.) Thanks

might as well get long tubes if ur doing a sts..... schoenfeld makes a set for $250 for a ls1 in obs silverado

Longtubes with a turbo are a bad idea. They dissipate heat faster than cast manifolds which is bad for boost.

STS systems don't rely so much on heat in the exhaust system. He can always wrap the pipes to hold heat in or have the headers coated inside and out.

This is true as well. I guess the fact that they are mounted so far back would make the heat issue irrelevant.

I read somewhere that there ar two types of motor mounts. One that keeps the engine at its current location but moves the transmission 1" foward and would require minor modification or the second option is that the engine would be moved back 1" back keeping the transmission in its current location. I personally like the second option since it would keep the weight more centered and should make the truck handle better.

Dirty dingo mounts are the best imo. They are adjustable and will go right into stock location
