The never ending Ls swap: Gmc Syclone
I dont get on here much anymore, not sure why im deciding now to start a thread, maybe because im bored and out of stuff to do right at the moment or id like to look back and see how far its come. This may (5/2017) will mark 3yrs since i got the truck and tore it apart for a "quick ls swap" as i told myself after driving the truck a memorizing 60ft and backing it into a garage for tear down.
Story goes like this got my SSS started doing small stuff to it, realized its big and heavy and hard to make fast even tho it is a fun DD truck, i wanted something really fun and fast to tool around in on nice days. Ive owned a syclone before and regretted selling it, i like ls engines, decided to try my hand at this. Yes its a real Syclone, and no i dont care that you think ive ruined it by LS swapping it.
Build consists of something i think will be really fun on the street and tough to find someone faster stoplight to stoplight, i dont have a peak HP goal but i want a fun responsive torque biased street truck i can one day drive to the track run a 9.9x @13x+ mph in, get kicked out and drive back home in thats reliable, simple as that.
Hoping final weight with me and 15gal of gas in it will be 3800lbs or less..
-ERL built iron 370 shortblock, wiseco pistons scat rods and manley crank
-LINGENFELTER cnc LSA heads
-Isky 218/224 cam, johnson lifters
-PRECISION 7675cea turbo
-AFCO front double adj coilovers, rear shocks w caltracs
-RPM lvl 5 4l80e
-Circle D billet 258 lockup 1b converter and reactor flexplate
-Front diff and tcase rebuilt by jason at rpm with a new torsen style lsd front diff so the truck is a true AWD and 32spline input in the bw4472 for the 80e
-MOSER 12bolt rear diff with a 33spline trutrac
-Chiseled performance sumped fuel cell with internally baffled
-Magnafuel 4303 pump and holley 120lb injectors
-Holley dominator and digital dash with e85 flex sensor so i can run it when i can.
Now onto the pics since thats all anyone cares about..
Day i got the truck
Test fitting oil pan and a L33 i had for a little bit then changed my mind
Few months later, before i decided to pull the front diff for rebuild
After paint and all new front end and brake lines front to back
Went to the rear
New cheap powdercoated shoes with some expensive *** tires lol, some nice custom forged wheels are on the list once the truck is done

As of right now im waiting on some crossmembers to arrive then i can get the engine trans and tcase all in. Next step after that is get some custom turbo manifolds/downpipe done along with a2a setup and then the long process of plumbing and wiring can begin hopefully to start the end of this project.
