JuicedH22 Posted March 8, 2012 Report Share Posted March 8, 2012 So over the winter, I decided it was time to say bye bye to the tired LS6 that has served me well, and do some upgrades, here is the spec sheet: -LS3 short block from new 2011 camaro (bought from SLP Performance) -TrickFlow 235 heads, milled 0.040" (11.68:1 CR) w/ powdered metal valve guides and custom exhaust valve sizing for my app. + some anti-detonation work to chambers (compliments of Mr. Brian Tooley) -Platinum valve springs -stock rockers with COMP trunion upgrade kit -FAST102 intake (port matched by B. Tooley) -LGM G6X3 cam -LGM Pro long tube headers (no cats) - stock Ti exhaust -LS7 lifters (after deciding CTS-VR lifters (aka "caddy racing lifters") were not for me) -Melling 10296 high pressure/high volume oil pump -Katech C5R timing chain -ATI super damper (917278 - 10%/10% underdrive) -McLeod RST twin disk clutch -Tick master/slave + remote bleed -Vararam Intake -Vararam Power Duct -LS2 90mm throttle body, with 90mm ring on intake - hand polished ID Other add-ons include: MGW short shifter, CCW classics (see my repair thread in the wheel/tire forum for restoration project on those), Sparco Torino seats. parts... http://i30.photobucket.com/albums/c318/Juicedh22/zo6ftw/2011-11-13_15-26-49_416.jpg out with the old, in with the new... (cam swaps are so much easier when there is no car in the way, or lifters in the engine) http://i30.photobucket.com/albums/c318/Juicedh22/zo6ftw/2011-11-13_15-17-35_85.jpg Also, took a picture to show the difference between the CTSVR lifters and the LS7 lifters... The snap ring and length of the roller shaft is noticable, as well as the oiling hole location (CTSVR on right) http://i30.photobucket.com/albums/c318/Juicedh22/zo6ftw/2011-11-13_15-43-02_97.jpg Quote Link to comment Share on other sites More sharing options...
JuicedH22 Posted March 8, 2012 Author Report Share Posted March 8, 2012 You would think for a $1000 intake that you would get some good craftmanship... http://i30.photobucket.com/albums/c318/Juicedh22/2011-11-23_13-33-58_547.jpg sharp edges, joints didnt line up, gaps in shells... So, with some 2-part epoxy and my sweet sanding skills, I filled the gaps, and smoothed the edges and seams. http://i30.photobucket.com/albums/c318/Juicedh22/2011-11-23_13-44-13_468.jpg The motor coming together too... http://i30.photobucket.com/albums/c318/Juicedh22/2011-11-27_18-36-04_310.jpg measured for pushrod length and checked PTV... pushrods were ~7.3625" at zero lash (11 1/4 turns on 6.80" checker) so looks like 7.425" pushrods will be what I run. (yes i used a solid lifter for test) Quote Link to comment Share on other sites More sharing options...
JuicedH22 Posted March 8, 2012 Author Report Share Posted March 8, 2012 PTV.... well here is where things are getting interesting... First the process. I bought some pottery clay (sort of like modeling clay) because it seemed less sticky and more compliant. I put a thin layer of oil on the piston also to keep it from sticking. I first made a complete round ~0.2" thick piece, mounted it, and sat the head on, to get the outline of the combustion chamber. Then I cut out the unneed area, including lower half... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-04_14-36-52_589.jpg Put the head on, bolted down. Using some solid (welded hydos) lifters from Kevin, and the checker pushrod at zero lash, I then spun the motor around a few times. Here was the result: http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-04_14-58-32_726.jpg I didnt like all the flat area, thought it might give me an inaccurate measurement, so I made a 2nd piece with the clay and did it again. http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-04_15-26-30_283.jpg (The cellophane was used to keep the clay from sticking to the head/valves) And here are the results... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-04_16-23-49_579.jpg It was hard to get an accurate measurement when you are dealing with 0.010" accuracy, but between the scale and the dial calipers it appears the PTV clearance on the intake is somewhere between 0.063"-0.070". Ideally the minimum is 0.080" The exhaust was over 0.125" so not worried on that side... SOOOO time to do the dial indicator method and get a more accurate reading on clearance. http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2352.jpg (ignore the value, not zero'd in the pic) Exhaust side: Valve drop: 0.230" PTV: 0.120" Intake side: Valvedrop: 0.190" dial indicator PTV: 0.055" Time to flycut!

JuicedH22 Posted March 8, 2012 Author Report Share Posted March 8, 2012 taped off the engine: http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2342.jpg Isky flycutting tool and modified head... (Thanks again to Brian Tooley!) http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2343.jpg http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2344.jpg Pretty time consuming, measure 18 times, cut once... repeat 7 more times. Once done, I also went back and sanded the sharp edges to a small radius, to prevent hot spots. http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2347.jpg Once done, reassembled and re-checked PTV.... This time had 0.080" on intake side... good to go! Disassemble head, clean deck of head and block, new headgaskets, and reassembled and final torque with ARP hardware... http://i30.photobucket.com/albums/c318/Juicedh22/IMG_2353.jpg Quote Link to comment Share on other sites More sharing options...
JuicedH22 Posted March 8, 2012 Author Report Share Posted March 8, 2012 Now to upgrade stock rocker arms with the COMP cam trunion kit... First, press out old bearings.... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-27_11-03-17_181.jpg After cleaning, and lubing the bore, press in 1st bearing... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-27_12-09-48_224.jpg Install trunion, flip over (placing washer on portion of trunion that sticks out), and press on other bearing... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-27_12-50-09_188.jpg Then just put the snap rings on, and done. Super Easy.... http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-27_13-16-17_438.jpg After that, I used the lathe to machine some spacers to replace the hillbilly washer stack i had been using under the fuel rail (which allows me to run the stock rail on the fast intake) http://i30.photobucket.com/albums/c318/Juicedh22/2011-12-27_14-59-08_601.jpg Quote Link to comment Share on other sites More sharing options...

No detailed pics of the seats yet, I will take some later. Not sure i want to keep them, I think I want fixed back seats, for FIA approval. BUT these torinos are super comfortable, and very supportive... though actually HEAVIER than the stock c5z seats! Idle is smooth as can be, very easy to drive in traffic, based on 1 day on the road. Though, I had a vengence VRX5 camshaft before, so I am used to a lopey cam in daily driving... Quote Link to comment Share on other sites More sharing options...

I had a trickflow stage 1 in my supercharged 5.0 and I was not a fan on cold days... please do on the seats- I am not surprised they are heavier- the c5z seats suck! I modified my bolsters for more support but the bottoms are starting to crack like every other c5 on the planet... I do like the z06 embroidery though... I know mine will be replaced at some point- a lot of guys like the carvaggios on corvetteforum- I would assume they are very expensive? AJ had a set of seats he recommended in his camaro- I will have to check what they were- maybe scat? Quote Link to comment Share on other sites More sharing options...

Yea, unfortunately you are very limited on what you can fit in the corvette, especially if you are tall like me and want the seat as far back as it can go, where the space is very narrow. yes the caravaggios seats are VERY expensive, nearly $3k new for a pair with all the hardware, every now and then you can find a used set for $1500-$2k... I have been looking at Sparco EVO2+, Sparco Chrono Sport (but these are not FIA approved), and Kirkey intermediate road race, or if I can find a pair (they dont sell them anymore) Sparco Roadster (what the caravaggio shells were made from).
