Re: My LQ4/T56 build thread

Have been busy working a lot lately, but have updates nonetheless.
Made a change in direction with the LQ4, going with more power.

NASCAR 799 heads CNC ported by Wegner Motorsports. Del-West titanium intake and exhaust valves (stock 2.00 and 1.55 size). PSI Maxlife valve springs good for .630, hardened retainers, locks, and seats

TSP MS3 Pro Cam 238/242 .600/.600 LSA 113

LS2 flat top pistons and rods with floating pins to raise compression. They have 39k on them, I need to have the rods checked for size to ensure they are usable. If not I will get a new set or just get Scat I beam forged rods.

Edelbrock 7139 intake
Edelbrock Pro-flo XT fuel rails

Edelbrock 90mm TB (I've switched to DBC)

new Brian Tooley Racing trunnion upgrade to rockers (peace of mind)

lq4 oil cooler adapter block off

pushrods are yet to be determined

Plug wires straight from China (pre-Trump taxed)

Spectre air intake kit with MAF installed. I may paint this wrinkle black along with the valve covers. Untitled by FlickrAccount83, on Flickr

PSI wiring harness (EV1 injectors, DBC). Was going to redo my lq4 DBW harness but I sold it for $300 with PCM and TAC and pedal so that helped pay for a unused, pretty harness. Bought it for $475. Glad I did this, now I can focus on other things instead of wiring.

Auto Meter gauges Ultra Lite II (MPH,Tach,Water,Oil Press,fuel, volts) and LS adapter kit

2005 silverado radiator upper and lower hoses (not sure how they are going to fit over the stock radiator but we shall see) Everyone swears they work.

LS2 timing chain

T56 Tick speed bleeder

Have the tank mocked up. Ordered Aeromotive FPR and a bunch more AN fittings. Fuel leaks or possible fire problems is the LAST thing I want to worry about so I haven't gone cheap here. Only name brand AN fittings from tank all the way back to tank. (yes, I consider Summit name brand, they make great fittings)

Finished stitch welding the stock rear control arms

Replaced Trailing arm bushings, track arm bushings, and front sway bar bushings with polyurethane. Also replaced all cab and radiator support bushings with polyurethane. Note to anyone else that may be as dumb as me....the trailing arm bushings only go in one way.
Getting out the old ones was a cinch, no smoke required. Just do the drill method, much cleaner in my opinion.

Rebuilt the Saginaw steering box. If I may help anyone out there, if only the input shaft is leaking at top, ONLY replace the seals to fix that, even if you bought the whole rebuild kit. It's not impossible, but time consuming and difficult to rebuilt the box. The nylon rings are not easy to stretch correctly to install. It can be done, just not worth it if you don't have a problem there.

Lares 201 rag washer (steering coupler) is a perfect oem replacement for me, wahoo! Ordered through advanced auto and had them price match.

If I end up painting or blasting anything, I'll need more air. Scored this compressor brand new never used for $300 on Craigslist. Thanks Craig!
Out with the old

CC'd head chambers to verify for CR number crunching and verification. Looks like they are not milled. There was still a couple bubbles left, so that's why it's not right at 64.45cc) FYI amazon sells a nice acrylic buret for only 25 shipped.....or you can spend two or three times the amount for the same thing through a auto parts website.
