Been going back and forth between the stage 1 and stage 2 summit cams for my NA LS1 build

would like to stay with the summit cams as I’m trying to build this engine cheap because it probably won’t be in the car for the long term, the car (1988 Monte Carlo ss) already has an ‘02 LS1 with the LS6 intake in it but the motor is bone stock as I type this, I do already have the 3200 circle D 4l60 converter and PAC 1519 valvesprings though, this car is daily driven in the summer and raced on most weekends at the local 1/8 mile

but here is the setup I plan on going with:
’02 LS1 shortblock
WS6store .045 MLS headgasket
factory port 243 head
LS6 intake
either ported factory TB or WARR 92mm tb but not sure if the warr fits on stock intake
schoenfeld 1-3/4 primary 3” collector longtube headers
the PAC 1519 springs I already have

and the setup on the car is:
3450 race weight monte carlo
4l60 trans with 3200 stall
7.5 10 bolt with 3.73 gear
275/50/15 m/t drag radial

not opposed to the stage 3 cam either if that would make the most power in this setup but I think the rest of the motor would be too mild for it but I’m not an expert

I do plan on taking some more weight out of the car too just haven’t gotten to it yet

stage 2.... or 3 if your springs are good enough

Summit racing cams

Stage 1 LS Ghost Cam. 222/233 115+3, .600/.575 Lift (probably wont chop much if your into that kinda thing)

Stage 2 LS Cam. 226/238 113+3, .600/.600 Lift

Stage 3 LS Cam 231/242 113+3, .600/.600 Lift

I would go stage 2 with the stall you currently have.

Honestly i think with a 4000 stall and the stage 3 would be sweet. I bet the stage 3 would put your G body in the 7.4X range in the 1/8 mile.

Thats what I originally wanted but couldn’t find one and the 3200 was too cheap to pass up, but that’s about what I predicted as well, it went 8.0 at 87.5mph with a lousy 1.91 60’ because of the stock converter the other weekend

maybr I could find someone who would be willing to trade a 4000 for a 3200

the 3.73s and low 1st gear of the 4l60 will make up some for the tighter converter

What kind of converter do you have exactly? If it's just a reworked heavier 11" or 12" factory style 3200 I would lean towards the stage 1. If it's a nice light weight unit 10" or something smaller billet ect, I would think the stage 2 would be great. I'd do the stage 3 with more weight reduction and a really nice 4k+ converter.

Sound like to me the 3200 stall was even holding you back from a good 60ft then. A good stall can eithier make or break a car.

Car still has the factory converter, the 3200 isn’t installed yet

Get you a 4K minium stall and that stage 3 cam. No need of later doing it over again to go quicker in the first place. Go send yiu a cool link you'll like by the way.

Posted mine up for trade for a 4000, hopefully someone is looking for a 3200

Go 4000 and stage 2 is my vote.

Peak tq will move higher as the cam gets bigger. That stage 2 will hit the converter nice. Stage 3 won't hurt but there are a lot of cases where too big of a cam will make you slower than a slightly undersized cam. The stage 1 is slightly undersized, the stage 2 is not. In my opinion the stage 3 is over sized for your setup.

Stage 3 is a little over kill for a 5.7, especially with stock heads and intake. The 92 mm throttle body probably make less power than the ported stocker, since there will be a huge ridge behind it that the air will not like trying to flow past.

Just send your converter to circle D for a restall. Then you'll have a freshly cleaned converter than you don't have to worry if there's chunks in it or a burned up lock up clutch. It'll all be fresh and new and won't cost much. Cost the same as shipping two converters back and forth trying to trade and good luck finding someone that would trade to go slower

Thanks for the advice! I will call them Monday

No go on the converter restall, 3200 is as high as they go on the 278mm, still thinking I’ll go with the stage 2 cam and hoping running a short tire and having the deep 4l60 first gear makes it work

stockA4

I still think that stage 2 has too much duration for a heavier 278mm converter. I'm sure it will drive just fine with a good tunup but it won't be ideal or as quick as it would be with a smaller cam. It'll sound cool though!

Stage 2 is definitely the best choice.

I just purchased a stage 2 cam last week. Can't wait to put it in behind my road runner converter

Sucks about the converter. Stage 2 and that converter should work nice.

With the 243 heads and ls6 intake you should make some damn decent power.

Tuskyz28

Car Craft magazine just went a 7.13 @ 97.97 mph with a 10 inch 3800 stall/turbo 400 tranmission in a heavy Chevelle. The cam was a BTR 227/234 duration. Im go say you'll be ok on a stage 2 with your current stall you have now.

I went with the Summit stage 2 cam, very happy with it. It pulls strong, drives nice and was easy to tune for a novice. Went 11.63 at 115 (2900+DA) last week but surely has more in it. The engine just has a stock ported TB, LS6 intake, stock 243 heads, the same WS6 head gasket as you pointed out, Yank converter, 3.23 gear.
