My LS1 Build.....

**Steve68** · 10-12-2006

I too was thinking drag combo from TSP, what if you run the Torquer II with the FAST intake?? with all the other stuff the same,

well on ls1s cams that have an lsa of 113 and up dont really sound choppy at all if anything depending on the tune sometimes you cant even notice it hehe ...you can always call thunder racing and they can grind a cam to your needs and likes hehe .Now on the injectors just to be safe i would go with 30s they can usually be found for cheap

**gEtyOpAPiOn** · 10-12-2006

you can always go to ls1sounds.com to find the right setup for you soundwise lol

I'm running the TSP 233/239 112 cam on my stock 346 with a PRC dual valve spring kit. The car lopes real nice and I find it very easy to drive around town and in traffic. Although I have an M6. I also find that the car could use some more torque down low, so that tourqer II cam you were recommended looks good.

I have ET 215 heads on order that should bump my compression to over 11:1 and have a set of 1-3/4" LT's ready to go in as well as 36 # injectors.

I'd also recommend porting that stock TB if you are going to run the LS6 intake. And also bump up those injectors to 30 #'s

2200 stall isnt enough get a 3000 at minimum in a lsx application

You would have to talk to Katech about that. I believe they are the ones who build the motors for the Cts-V speed challenge series cars

I had TEA heads on my C5 and loved them never a problem. They really like Futral cams too. I ran a F11 228/230 112+4 and it had a snotty lope.

Midyear Corvette guys would come up at shows to tell they loved how it sounded and that their old side pipe car sounded like it when they were younger. The car turned 436rwhp and 415 rwtq with a 6 speed.

Also I have ordered parts from TSP and do not plan on dealing with them again. Parts arrived at seperate times and they seemed generally disorganized.

Thats odd, I have ordered numerous parts including my cam from Texas Speed with great results. They have great customer service so far and in fact I called them up and placed an order for some forged pistons today.

Right now I'm looking at going through Livernois Motorsports. They're about an hour from my house and I can save a bunch on shipping. Plus they have a chassis dyno and do retuning services for PCM's and they're prices are reasonable.

**Steve68** · 10-27-2006

Keep us posted, I'm looking for a good cam/head package, with good prices and tech,

**trapin** · 10-27-2006

As soon as I get the garage situated after the car comes back I'm going to be diving into all that aluminum wonderfulness. I can't wait to bust it down. I haven't busted down in engine since the last Bush was in office.

**Steve68** · 10-27-2006

I envy you on the paint, but I'm home with a sicky today so I get to play in the garage, just put the gas pedal on. and the other night went the clutch and brake maybe I'll get to the wiring harness,

**trapin** · 10-29-2006

Aw man...don't get me started on the wiring harness. I can't wait to do the wiring harness on my car. From what I remember I sucked at electrical stuff. I just hope the instructions it comes with are simple enough for a monkey to do it. Plus you throw in the LS1 and the computer and I could be doing the wiring on this car for the next 3 years. LOL!!!

**Steve68** · 10-29-2006

Look at the stickys on LS1 tech, or you can send it to Wait4me performance or Speartech, both are supposed to be good,

**WS6** · 10-29-2006

3500 stall on a protouring car is nuts. Your back end will come around on you going around a corner if your rpms dip below 3500 and you end up flashing the convetor coming out of a corner. Happened to my friends 00Z on road ATL. Sent him into the dirt.

I think the 224/228 combo would be better. I did recently install a 228/228 cam from TSP in a 98 SS with an auto and 3200 stall.He had the stock 3.23 gears though. Had excellent power with only a little lowend loss. Had a good sound for an LS engine. I do not recommend going for sound on an LS especially an auto. The tight LSA cams are a pain to tune for the street with the auto. It can be done and Livernoise should be able to handle it if they spec something like that. If you notice a lot of companies have two cams that are the same except for LSA. The auto cams are usually +2 over the manual cams simply for drivability and tuning ease.

As for your combo in general, do not skimp on the heads. I think for a budget build the ported LS6 heads and 5.3 heads are great, but the AFR, RHS, and ET heads are better and would suit you better for a pro-touring car. The runner volume on all the ported GM heads is 230+cc in order to flow those numbers. The new casting heads are 205-215cc. They should produce a lot more midrange and low end torque due to the higher velocity the air will have. Keep the cam below 230 on the intake and duration with the LSA at 112-114. This will produce at least 400hp and 385ftlbs at the wheels through the auto but more importantly, the power will be broad and the torque will be strong throughout. 2600-2800 stall with those gears will do great on the street. Mind you it will not be optimal for drag racing as you'd want a higher stall, but this isn't a drag car your building.

Also never listen to a drag racer tell you what specs to use on a road course/ pro-touring car. I want to slap the people that say torque doesn't matter and ,yes, I have heard that said all too often.

Good luck and if you go to Livernoise for everything you should be pleased as they have a reputation for doing really good work. Let them know this isn't a drag car and what your intended purpose with the car is and they will put together something that will meet your requirements.

**trapin** · 10-31-2006

Trey....thanks alot for that information. You make some great points. You mentioned the 5.3 heads would be good for a budget build (which is pretty much what this is going to be). I have the oppurtunity to purchase a set of 5.3 heads from a friend who owns a cylinder head shop here in Michigan. He says they are brand new castings that he CNC ported, 58cc, 2.02/1.57 and flow 310. They have all Manley hardware in them. He says he'll sell them to me for $800. For that price do you think I should jump on them? What potential valve cover problems or any other issues do you see if I go with them?

Thanks. If these are my heads, all that's left is the camshaft and I have my engine.

**Payton King** · 10-31-2006

Mine are from TEA and flowed 316 at .600. Only difference in a 5.3 head and 5.7 head are the combustion chamber size. Easier to bump the compression with. Mine are milled to yeild about 11.3 to 1 compression. Since you are running an auto I am guessing the 224/228 on about a 112, but there are way more qualified folks to help you make the correct cam selection.

$800 for the pair is steal. No way can you go wrong and all the stuff is the same...ie, valve covers

**Steve68** · 10-31-2006

Sounds good Tony, If you need parimeter covers I got you covered, snicker,

**BuddyP** · 10-31-2006

Tony, keep me posted on those heads. I didn't realize the 5.3's where a direct bolt on. I ran across a set of ported '98 LS1 heads with 2.02/1.57 valves for $650 (all new porting and valves) but the people I checked with didn't think they were a good buy.
