Any external differences between LS1 vs LS7 ??
 

Hello!

What are the major differences between LS1 vs LS7 , and i am only talking external differences for mock up use. I have LS1 engine and can i trial fit headers , intake , wirings , assesorys,engine mounts with it ?

I know the oilpan is different. I am planning to bay one as used to make oil lines in future.Does it bolt right on LS1 ?

Yep, everything else will bolt up - trans, headers, etc. The exhaust ports are different on an LS7, but LS1 headers will still bolt up.

Not to highjack....but what about an LS2 and an LS7?

Thanks Scott!!! Great news , now i can do all the fabbing first and get the engine last.

I'm not sure about the water pump, though. Anyone know if they are signicantly different?

EDIT: The water pumps are basically the same with a slight difference in the intake manifold area for clearancing.

Awsome! Then i can build cooling and everything over it :cool:

What are you doing for accessory drive? That's my current research project. :D

Ilike the looks of fbody..espially after seeing Steves penny:bow:

I recall cadilla CTS (??) had nice looking too.Big question is can i use stock gm ac compressor with vintage air systmem?

EDIT: I found this system from DSE . As much as i like all DSE stuff i dont understand the value of this 3500usd system vs stock Fbody.Not even looks.

I don't believe that the stock compressor will work with Vintage Air. But they do make a bracket that adapts a Sanden compressor to the stock A/C bracket and locates it in approximately the same position.

That is the DSE new setup eh?

Looks pretty good, but looks like the water pump will not allow a factory manifold or throttle body to be used with it because of the T stat location.

Here is your other alternative- The Sidewinder.
