Hi
i wanted to get a couple actual experiences
about moding the ls1 on a non z c5
1st of all
Planned in NA.
cam. & tune ...and headers if they really make a decent difference . exhaust will be catback only i am in cali and have to visualy be smog legal...lol

So regarding cam
I like it agressive & nasty the car will be aweekend warrior mainly. Mpg doesnt matter
I read alot about certain cam companies
but would like to get a recent 2018 update on. What cam can get me the most nasty power + tune.
a custom cam can be intersting if its in the same range as a of the shelve.
of course i will upgrade springs accordingly.

Do i need 243/799 heads or stock?
I think i head about moded 5.3 heads with bigger valves as a option too?

Headers will be simple longtubes if i decide too.

Any suggestions.

Your question is to broad. Whats your budget?

Budget heads? LS6 from The Race Engine Shop (Forum Sponsor and some of the smartest C5 builders)

No budget? Trickflow or AFR.


I dont live in Cali so I dont know what you can get away with in terms of smog and exhaust.


Good cam specs dont change, companies just take the cam specs that are proven and change them by a degree or two and rename them. New lobes every year that make more power than the last blah blah marketing blah blah.

If you go with trickflows talk with BTR (Brian designed the Trickflows). I ran a 235/242 110+4 with the 215 CNC Trickflows and it ran fantastic.

If you go with cnc'd ls6 heads or other stock heads, get a custom cam from the company that cnc'd the heads.

Talk with the shop about your goals with the cam. What you want for sound and the power band you want




Or skip all of this and call Andy or Josh at A&A Superchargers and get their smog legal kit

If I were to go NA 346 again I would do the 215 Trickflows, FAST 102 with 90mm TB, ARH headers and Xpipe and a cam 230/232 112 ish cam.

i want it onna budget lol..
So ls6 heads it is.. If cnc ported is in the budget i ll look into it..

Supercharger great but i have a boosted toy that is a handfull..lol

You can get your stock ls1 heads ported to save money as well. A good ls1 head port job will get you 35 to 45 rwhp.

Time for a C-5

Plan the entire package together. A cam profile for factory exhaust manifolds looks entirely different then a cam for long tubes. Cam specs need to match the heads too. Don't forget about the other parts "while you're in there"...timing chain, oil pump, lifters, trays, balancer (at least pin it). Valve springs and pushrods are a must with a new cam.

Sebambam

good info..
But how cost effective compared to get 243 heads?

Sebambam

yes thats why i collect all the infos now to piece it together right.
Im 99% going to use longtubes..
Springs. Timing chainetc will be replaced of course.

Realistically? A cam only z06 c5 makes 410 to 440, so expect to make that with stock ls6 intake and heads with a cam. Ported ls1s will make 420 to 450 with a ls6 intake.

Theres a ton of stuff to factor though in terms of price and power output.

Sebambam

That will totaly match my goals..
Any proven cams ou there with
ls6 intake + ported ls1 heads
Ls6 intake+ 243 heads
+ longtubes

Boredom
