What cam to go with.
Most people won't take the time to check geometry to get it right, most people are therefore told not to do it by the 5 guys that respond to everything with their hate posts.
Only thing is the Lt1 stock heads only flow so much so at a certain point extra lift from 1.7s will not net any gain whatsoever.
There's also the idea of exhaust ptv clearance in extreme cases.

I was going to run that LE cam he was mentioning in a 383 but ended up doing a 355 and used his 223/230 112lsa cam. I need to pass emissions and going reason i went with slightly smaller cam and on a 112 vs the 110. IMO you will have very well rounded dd cam with the extra lope at ldle with the 110lsa. If you cant afford a set of ported heads and are going to pull them i would atleast do a valve job and a small milling would bump the compression to few more ponies.
Cam
Hardened pushrods
Good Spring kit
New stock timing chain
1.6 7/16 NSA roller rockers (if you plan to go bigger later or SA will work if you dont)
Guideplates if going with NSA rockers
ARP Rocker Studs
LS7 Lifters (Stockers should be fine but if they no good use the LS7s)
Gaskets
30lb Injectors (Might be close but im sure your stockers will be close to being maxxed out)
Tune!

I would do it. That's about as big as would make sense on the stock heads. Though I doubt you'd see any benefit. After that the flow at any higher lift barely shows an improvement worth dealing with and you'd probably only have more wear and tear on the springs and such required for that much lift.

R3DLT1, are you the one doing the 503 swap right now? I think i saw a post on another forum for it. If thats you, can you PM me what all you went with? Im having a hard time picking everything out, or just going with the kit.
Bigbad: pm and ill help u out as best as I can.
Since the LS7 lifter is the current OEM replacement lifter (as in you go to the dealer, that's what they're going to put in your car)....I would say yes. Since the manufacturer would most likely not make it so you need to get custom length pushrods to repair a failed lifter, you should not have to replace them. So you "should" be able to use stock length pushrods....

Ls7 will work on ur application. Like stated above it will be best to use a adj push rod length checker to check the correct length. In all really 7.2 "should work" since ur not changing head gaskets nor heads have been milled but check to be safe. U don't want all ur hard work to go to waist

Those who have recommended you do that are answering in a responsible way since there's NO WAY they can know for sure what length pushrod you'll need.
Since you're admittedly a "noob" it's best you learn the correct way from the beginning. You should MEASURE!

Im running the cam in sig on my DD. And pull your head out of your *** and listen to everyone. Buy a pushrod length checker and do it right. There was a guy in the Gen III section who assumed he needed a certain pushrod length. he wiped every cam lobe and destroyed his motor in 500 miles
