love the headers!!

 

update time....

burned in the subframe connectors and i have started on my 8.8 hybrid build. should have it done in a few weeks. hope to have the car on the rollers by early may.

 

I love third gens. And I ****** love LSx third gens. AWESOME MAN!

 

started a build thread on the 8.8 in the gear section

8.8 build is finished, on to the dyno on friday for the tune.

will need to do some detail work to center the axle at a later date, didn't do my due diligence and now my rear is 7/8" too far back. going to drive as-is this summer and enjoy before #4 gets here. this winter i'll pull it back apart and get the ds chopped down and move the torque arm mount if i have to.

8.8 held some 2800 rpm dumps, and with the jegster ta and lcarbs/boxed lca's it bites hard.

 

dyno numbers are in...

391hp/381tq

didn't hit the 400# that i was looking for, but i'm still very pleased. justin said more cam and more compression, but i explained to him it was not a track car or a racecar. the car does what i want it too and we'll see what the track numbers say. he went and did the street tune and when he came back it put down 371/366. he worked his way up from there.

i think their is some more left in it, my pinion angle has been giving me fits, and i think it was binding a little during the dyno session.

the cutout added 10hp/10tq when opened, so i'll definitely be going to a 3.5" single exhaust. it idles better and drives better, so i'm happy with the end result.

trying to get the pinion angle dialed in has been a headache, the car was smooth all the way up to 130mph plus before. now has a vibration after 70. so that is my new mission.

 

Perhaps this was covered long ago, but were you considering 4" instead of 3.5", or ??

 

no, at my power level, i feel 4" will be overkill. i'm planning on running 3" pipes off the headers to a merge and 3.5" out the back with a dynomax ultraflow in the stock location with a single outlet and turndown.

then i can eliminate my cutout....possibly. tired of hearing it rattle.

 

here is a video of one of the dyno runs, this was through the exhaust.

the bottom one is an idle video, you can hear the loose cutout rattling

 

made some slow progress over the last 2 weeks. getting the car "ready" for this spring. needed to clean up some things that were left over from last year.

first, i was able to get my intake finished up. i cut a small chunk of aluminum tube that i had laying around and drilled a hole for the IAT sensor. everything else went together without much mofication.







this weekend i had a short blast on the rear end project. pulled the rear out, ground the welds down on the LCARBs and took the air chisel to bust them loose. i cut down the nose on the torque arm to give me the 7/8" clearance i will need. put the new LCA's together, decided to try the 3 piece poly joints, mounted them on the car, and put the new LCARBs on the axle.

i still need to hook up the axle and do some measuring before i weld the LCARBs on. then all i have to do is measure for the drive shaft recut and i should have this project wrapped up.







then it's on to new head lights and secondary harness with relays to make them brighter.

 

Love the car! Let me know first if you ever part with it

 

thanks, there are 2 guys in front of you that would have dibs first! this car will go to one of my boys someday.

 

Even better to hear! Hope you are enjoying it.
