ahh ok

well whats the quest for now? LS' are in the 300 hp range are they not? Getting another 100 out've it should be easy, with minor things like the cam you mentioned, headers, and tune.

I am no help on a cam, there are so many cam options for all v8s its mind boggling, and headache worthy

Just gonna nos it and go, maybe a cam. Any recommendations for a cam?

Ronin kit is lighter, engine is easier to insert and remove, more exhaust and engine bay space and exhaust can be routed straight.

With Granny's your exhaust needs to go over the trans cross member.

C4 Corvette aluminium driveshafts work with the correct rear flange swapped on. Or Granny's driveshaft.

Orders Granny's swaybar relocation brackets, and Stu Kelly Motorsports clutch master cylinder bracket.

As far as a cam, yea there are many that will get you to around 400 WHP with what you have. You'll need to upgrade the valvesprings at a minimum for any cam. You'll need bigger injectors to make the 400 WHP.
As far as a recommendation, do you value nicer street and low RPM manners? I'm a big fan of the ASA cam, I have one in my car and it made 401/401 to the tire. It has got a lot of overlap so it sounds pretty mean. Low RPM manners are not the best but it is pretty street able. It has relatively low lift ,which is easy on the valve train, and it has a wide powerband.

My car makes over 350 ft.lbs. of torque form 3500 RPM to 6700 RPM.

There are many other cams that will get you there, some with a slightly narrower powerband, that have better street manners, some with more aggressive lift, lots of options. With an otherwise stock motor you don't want to get too aggressive, but 400 WHP or close is doable with a good exhaust and intake.

Hmmm. Maybe ill just leave her stock and run the nitrous kit for now. Have some pondering to do.

BTW im running the 4l60e for now, so i think theres no need for the clutch master cylinder kit as of yet.

What is the ECU/Engine out of? Is it not a candidate for using HP Tuners?

It's a Camaro/Firebird engine, harness and ECU. HP tuners will work on it it's going to need a reflash anyway to turn off VATS so it can run at a minimum.

FührerTüner 04-25-17 12:00 AM

OK so i think i have some things figured out.

1. Cam: 224 112 +4 good streetable cam with flat torque curve, and a lil lopey. +50rwhp???

2. I know i need valve springs. Not sure which ones to get or what the differences are. I'm thinking comp 918s, but thats just from what i read on other people's setups.

3. Short header with catless X straight pipe. Cold air intake. Port TB. +20rwhp

4. NX Plate wet kit, 100 shot.

So that puts me close to 390-400whp without the squeeze. Should i be fine with the stock injectors? Because i really dont wanna spend more money.

FührerTüner 04-25-17 12:14 AM

Oh yeah and this came. My birthday was 2 months ago.

Plan:
eBay turbo build on a 30yr old jdm t2 block with no rebuild
strap NOS to an LS pullout

Godspeed, sir.

A couple guesses:
"Hey! Watch this!"
"What could possibly go wrong?"
"I got this."

In for rod knock.

Haters gonna hate. Keep workin on that interior bud!:icon_tup:

FührerTüner 04-28-17 01:18 PM

Well engine made it in one piece!

On top of the Nitrous kit I purchased a Comp cam, 223/230 .585/.600 111+1, should give me a nice lopey idle to make all the girls panties wet. But really, has a supposed flat torque curve, super easy to drive even with the lopey idle. Springs on the way as well. Expecting 350whp

Purchased an engine install plate that bolts to the intake manifold area. this thing was a bitch to get off the trailer using the tranny bolts.

Picked up a new soldering tip for my Weller, some shrink tube, and 200 feet of 18ga wire to start the harness rebuild/reroute.

Still waiting on my granny kit. Those guys dont like to answer the phone after they have your money.

Ive been working so much lately i havent had time to do shit. Think im off this weekend. Cant wait to start working on this thing

Slow progress. Anyone have any recommendations on where i should mount this relay and fuse block? I made a lot of slack on the harness, pretty much free to go anywhere on the passenger side of the cabin.

Harness finally complete. Wires ended up being tighter than I originally laid it out. Wanted to run the harness in the valley between the heads and the valve covers, but I'll have to settle with the stock location.
