Injector & cam size
Injector & cam size Hello all.
I'm trying to figure out what size injectors and cam I need. I have looked at the cam faq section so I have a better idea but still need a little guidance
I will tell you all my combo first, then how I plan to use the vehicle which will be 86 Camaro
2001 5.3 to be bored to ls1 specs
Reuse /recondition stock rods & crank
Ls6 intake & throttle body
Fbody accessories and brackets
Hyper Flat top pistons
Long tubes
Tea stage 2 -243 heads( the 243 heads came off LS4)
Built 4L65e or 4l80e
I want my compression to be 10.1 - 10.5 range
Will use a stock posi unit or a posi 8.8 rear end from Hawks or Spohn
Im thinking a cam like 216/220 550-580 lift/ I dont know the lsa
Using pump gas-93 , I want something I can possibly daily drive and have a wide powerband with 6k rpm limit
I want low end more than top end power but I dont want it to max out in the middle If that makes sense.
At the least, something I can keep up with the ls3 camaros and the coyote ford engines..
If my expectations are not doable, please advise me. I really want to keep up with the newer camaros mustangs dodges... It doesn't necessarily need to be a daily driver, but at the very least, something I can drive 4 hours away to events and such

A4 or m6 ?
Your compression will be around 10.5 : 1
gtp 36 lb. Ev1 injections will be plenty for that setup and can be had for around $100.
You are going to need to spin it a bit higher than 6k.
Imo if your goal is to keep up with newer cars you're going to need a bit more cam.

Would I need valve reliefs in the flat tops?

Stage 2 Summit. 226/238 .600 113 lsa will work VERY NICE and drives great!> even with the ls6 intake and im assuming y pipe still should made 400+ tire.
Edit, If you want a Ghost style cam that's very Mellow the SUM-8715 would be your best bet. Go check out my build thread . I ran the stage 1 and 2

Injector wise, 36 pounds to 42 pounds should work out nice with heads your using and a good cam.
Cam wise what Mavn said.
Why compression in the 10 to 1 to 10.5 to 1 range with 93 octane available? Forced induction later?
My 3rd Gen RS is LS swapped and runs 11.3 to 1 on 93 octane and can daily drive or do 1,300 mile trips etc. Same TEA LS6 2.5 heads. My 72 runs 10.85 to 1 with a carb & HEI, occasionally needs octane booster on a very hot dry summer day.

Just my opinion. Nothing more . Tsp 228/232 111 lsa . S60 3.73 and s-trac . Yank ss4000 converter. +Those heads and some good tire. GO KILLEM!!!!!
i has almost that same cam but on a 113 lobe sep and I really didn’t like it. I like the new cam much better. But I’ve grown out of liking a bunch of noise and shaking at idle at a red light. And the gas smell at idle. Don’t care for that anymore. This new summit cam is super docile, lopes just a little. Drives like stock. And pulls to 7000. It made 450rwhp in mavns car. What more could you ask for? I was afraid I wasn’t going to like it or my car would slow down, but it feels like it picked up power. And I really like it.
