Sorry, if this has already been posted, did a search and couldn't find anything. How would an ls1 cam swap differ from a gen 1 sbc cam swap in general? Would it be tons more complicated? The reason I'm asking is because I'm wanting to install a cam next with the help of one of my mechanically inclined buddies. Unfortunately, he doesn't have a lot of experience with the ls series mainly just first gen sbc's.

Well it has been awhile but...
as I remember the IM is pulled on a gen I but not a gen III.
Pull TC (same). Pull chain too.. Upper timing gear needs to be removed (gen I)..
Remove VC's and pull PR's, lifters and rockers and # so they go back in the same hole (not necessary to # on an LS motor). Reusing lifters are not recomended on gen I's so new ones should be used....
Keep in mind a flat tappet cam needs lots of assembly lube and a high zinc oil to break in properly (not necassary on our HR cams).
I am sure I have forgotten a lot but hope this helps... This is what I can think of so far..

About the only similiarity is that the cam pulls out the front of the engine, lol. Actually, it's much easier on a LS engine. Check out this link. LINK

gen 1
intake off to get to the lifters, balancer off, water pump off, usually radiator out so u can take the cam out, timing cover off, cam gear off, pull cam.
LS''s take about an hour a gen 1 sbc a couple lol
