Cam and Head Package?
I had a 5.3 liter Stage 2.3 upgrade with the valvetrain that will support a cam with a .660 lift. a 233-239 duration cam with a 112 lobe sep. and a .595/.603 lift ( bad *** runble) full long tube no cat B7B exhaust. I just bought a FAST 92 with a 92 Throttle body they told me they would need to install these items approx $200 as long as you bought th coolant bypass and the wireing adapter. They will tune it like this a highway tune (with a good tuner no prob) $250.
Now they wil replace the Cltch/Flywheel/Throw out bearing/ Piolot bearing/ Pressure plate.
Now I need to take it pretty easy for about 400mi. to break the clutch in... all of this with me supplying the 2,900.00 dollars in the parts needed, they told be the Clutch assembly swap would be approx 1350.00,,,,yeah, OUCH! You dont own a Mustang anymore....LOL... COMPLETE WITH SATISFACTION!! In the end they told me I would have no less that 450rwhp. Not bad for a stock LS1

. I talked with my neighbor which might be helping with this major install as its becoming more and more in depth. He's done a few engine builds in his time. He said to make sure that the transmission can support the added hp. If I am correct the transmission that I have is a Borg-Warner T-56 transmission which is capable of running up to 600+ hp. If I am wrong please let me know.
So here is the list so far that I have built up to...
- Heads
- Cams
- Headers
- Intake Manifold
- Throttle Body
- 42# injectors... or 60#?
- High Performance Clutch 650+ hp rated
- Rockers ? (suggested by my neighbor)
- Timing setup? (just an idea)
Anything I am missing?
i want to change the cam on the car because its too agressive for a daily driver. im loking for a cam that i can still get some power out of the car but at the same time i can drive the car and enjoy it.. with the current cam the car was making 542rwhp and 496 torque. i do not mind loosing a couple of hp as long as the car drives good. im also planing on adding a 200 wet shot of nitrous. what do u guys recomend me to put on the Z. the main thing is to have a good gas milage and at the same time some extra power compare to the factory cam so i think that i will just need a liltle bit more than the 02-04 cam.
also if u know any good shop in the miami area let me know ..
thanks

You may want to add an underdrive pulley to your list. Pushrods. 42# would be fine for a H/C setup, even 38s would be plenty. The stock rockers will be fine. If anything you can have Harland Sharp rebuild your stock rockers if you want.
Get a remote bleeder for your clutch also while everything is apart. Makes cleaning the clutch fluid a snap.

How soon are you looking to purchase? If you need me to put together a package for you i will. Lancaster is only an hour or so from me.

no offense but if your looking for a big hp engine, to do them right it is not cheap. and have a professional engine builder do the build up. YES projects are fun, but do take time.
have someone like TSP, HKE Racing engines or Lingenfelter build your engine. Then you and your friend do the install.
For a $3,000 budget ( if I read that correctly) I would not open the engine up IF YOU WANT RELIABILITY. LTs, X-pipe free flowing exhaust, CAI ( Fast92/92 for an extra $1200 )and a great tune.
Plus that can be installed in a weekend.

Big HP numbers are SEXY AS HELL. But does not mean reliable.
I have been looking to build or have built a new engine too.
But my LS6,
with a 224/224 581/581 112 cam,
stock 243 heads with comp 918 springs
Stock LS6 intake with TPIS 76mm tb,
my own CAI
stock injectors- changed two years ago.
pp oil pump with 3qt accu-sump and oil cooler
TPIS LTs Random tech high flow cats and straight pipes
puts out about 430-425 rwhp and 410 rwtq
with 22,000 hard 3000 to reline miles
Stock clutch, trans and diff - Trans and diff have coolers attached.
Really should have put in a better clutch and light wt flywheel - but didnt
just keeps beating the chit out of bigger hp number engines.

The Best of Corvette for Corvette Enthusiasts

Reality has sunk in and now I am hoping to get at least 460-470 rwhp with the setup. My budget has increased to around 5k-6k now so I think I can get those numbers and still have a reliable engine afterwords. I will be using the car for daily driving.
Frans96ss this will be a project that I will start to undertake over this winter (in the next 2-3 months) buying parts along the way when they are on sale or I find a good deal.
nickolbag what underdrive pulley would you recommend?

for relativity I would strongly suggest that you keep cam lift to no more then .600.
Have seen lots and lots, more then a dozen engines go boom this past two years. not counting LS7s all have had valve lift OVER .600 did not matter what springs ppl used either. and guys tried to do it on the cheap
Good Luck

BTW: Is this cam not aggressive enough for 460-470 rwhp?

That is a very good cam, Slightly larger then one I use now. I think 460 is pushing it with that cam. HOWEVER, 460 is just a number. Once that is installed it will give you lots of SOTP acceleration AND big smiles

I think 440 rwhp is more realistic with that cam.
Also I was looking at some heads and I found this one at a decent price but I wanted some input on the specs of it.

The AFR heads are just sooooooo pricey. If getting a cheaper head will not adversely affect the total output then I would like to go with a less expensive head. If it will then I will suck it up and buy AFR
that is 40 hp more. or about 390 with a good cam.
ie those heads are not going to get you to that number of 460.
if you really want tht 460 number then AFR 205 heads or Trick flow 215 heads and then that cam will get you there.
but cheaper heads DO EFFECT the outcome. the 5,3 heads will not get you there.
seen three engines built with 5.3 heads. Not sure if the builders got much more then they aready had with 243 heads.
I will dig up some head flow numbers for you. ( I do not sell product so I am not product bias, just like to see great engines, not guys spend loads of money only to rebuild 12 months latter )
if you want to stick with the PP heads, which are good heads i would use these
