kevinz Posted September 30, 2014 Share Posted September 30, 2014 The shop that I'm getting my parts thru for my ls1 swap says this would be the best can for me. Not a dd but I want something very streetable. Not sure if this cam is too big. 227/230. 640/605 111 lsa. Quote Link to comment Share on other sites More sharing options...
mattd428 Posted September 30, 2014 Share Posted September 30, 2014 Lift is large but duration and lsa aren't too bad. Should have a nice lope. Quote Link to comment Share on other sites More sharing options...
Zzeal Posted September 30, 2014 Share Posted September 30, 2014 Popular Hot Rodding built an LSx and swapped the heads, cam and intake. The cam was a 230/232 - .591/.595 - 114 lobe sep.. They described it as a maxed out cam for the street. A friend of mine tried a similar cam, a 224/232 - .590/.590 - 115 lsa in a modified LS2 and wasn't very happy with it's rough street manners. I'd first look at LS1howto.com's cam section, then call some cam manufacturing tech people for their advice. Steve Quote Link to comment Share on other sites More sharing options...
kevinz Posted September 30, 2014 Author Share Posted September 30, 2014 Thanks. Good advice. Ls1howto.com was a good read. Learned a lot. So my can seems to be borderline for street. he says that cam will work well with the smaller runners on the JCI headers. Does that make sense.

RebekahsZ Posted October 1, 2014 Share Posted October 1, 2014 Have you thought about what you WANT from your power plant? That's super important. The difference in power between a stock LS and a super-de-duper souped up L6 is just incredible! If you are going to street drive and autocross and even drag race your car, I recommend you go with a stock cam. The factory engineers have done a really good job with the LS series and a lot of times we only screw up what they have done well. With my stock cam LS2, I can lug around corners in 3rd gear with ease. I can stop momentarily at a stop sign and take off again without depressing the clutch using first gear. I can cruise at 70 in 6th gear at about 1500 rpm (tall tires). I can autocross in 2d gear if I want to try for a faster time, but I can keep the rear under me better and not exceed site-restricted dB limits by staying in 3rd and running a lower rpm. The car does 1.43 sec 60' times and runs 7.0 at 100mph in the 1/8-mile, 11.0 in the quarter at 126mph and 148mph in the standing 1/2-mile, and Im hoping to break 160 in the standing mile. It doesnt run hot and i can hot-lap 26 passes in a night without a mainenance issue. ALL WITH A STOCK CAM. As for me, I plan to spray this motor to an extra 150hp before I remove the water pump to install a bad idling cam that gets me MAYBE 70 more hp AFTER adding a FAST intake ($900), larger throttle body (?$), and cam kit ($1000 after cam, lifters, springs, retainers, pushrods-and a chance to kiss a valve with a piston). Just my 20-cents worth. Get the dang thing on the road! Quote Link to comment Share on other sites More sharing options...
kevinz Posted October 1, 2014 Author Share Posted October 1, 2014 Already ordered the cam but after that post I think I will hold on to my stock cam and springs in case I decide to go back. I just wanted to put a z06 cam in it but everyone I talked to said don't waste the money and to get a good one. This swap got a little over what I had first planned. One of those while the motor is out things. Quote Link to comment Share on other sites More sharing options...
Jay Gadsby Posted October 1, 2014 Share Posted October 1, 2014 I have been fighting the urge to do the "while I am heres" on my 5.3. I think I may have kicked it for now. Gonna enjoy the stock power on the engine first, then the seat of the pants dyno will love it when i do end up camming it. Quote Link to comment Share on other sites More sharing options...
Phantom Posted October 2, 2014 Share Posted October 2, 2014 I was watching "Bitchin' Rides" the other night when they installed a stock LS3 in a '78 Firebird. The first run on the dyno had the car at 326 HP / 326 ftlb of torque. My stock '98 LS1 does 325/326. After further adjustments they got it to 366/326 The Firebird and my car both have a T56. Thought I'd see a bit more rom the LS3, even at a stock set-up. Quote Link to comment Share on other sites More sharing options...

There are some great posts in the archives about comparing dynos, if they're not stickied they should be. I've seen as much as 50-60hp swings with the same car running on different dynos.

Phantom Posted October 2, 2014 Share Posted October 2, 2014 (edited) Uhh - Kindig is in Salt Lake City, UT and I'm in Yakima, WA. Kinda obvious that they weren't run on the same dyne. The 366 RWHP is consistent with the GM claim of 430 flywheel HP for the LS3, though. Not sure how much GM is underrating the LS3 compared to what they did with the LS1. My sons LS1 with a cam dyno'd at 378 RWHP. Not on the same dyne though so maybe it's only 320 or so? Maybe mines only about 265? What the heck,maybe mines 380? Only thing is that both the original numbers are consistent with what LS tuners expect out of stock LS motors.

RebekahsZ Posted October 3, 2014 Share Posted October 3, 2014 The drag strip is the only dyno that can't be disputed. Quote Link to comment Share on other sites More sharing options...
socorob Posted October 3, 2014 Share Posted October 3, 2014 I was talking to someone a few weeks ago who said 2 different dynos he went to showed about 65 hp difference.There is no weights and standards type body that checks to make sure all dynos are the same. He said the mustang dyno showed lower numbers than the other. Thats why its important to use the exact same dyno if youre doing any tuning on your car.

Gus Posted October 3, 2014 Share Posted October 3, 2014 What displacement is the LS engine? What type of transmission, Gear ratio, stall size if auto and how do you plan on using the car? Quote Link to comment Share on other sites More sharing options...
kevinz Posted October 3, 2014 Author Share Posted October 3, 2014 It's stock bottom end 5.7. T56 trans Gear ratio 3.70 lsd 99% street. Not a daily driver. Just a toy. Stock 243 heads. Ls6 intake Underdrive pulls Ls6 oil pump Ls7 lifters Ls2 timing chain Monster clutch stage 2 JCI headers. The small runners on the headers are the reason he says this cam will be the best for me.

Naptown Dave Posted October 5, 2014 Share Posted October 5, 2014 (edited) It sounds like it'll be a little lumpy with the tight lsa. You will have to let us know how about its street manners are. I bet it will sound badass Edited October 5, 2014 by Naptown Dave Quote Link to comment Share on other sites More sharing options...
