Re: LS 6.0 swap

I welded v-bands on mine. Heads, get the 706s ported + larger valves. Should be a killer combination.

Re: LS 6.0 swap

Spent the afternoon yesterday pulling 5 broken exhaust valve bolts....great fun!

Should find out how the block is tomorrow. Figured out after all this time I was using the wrong motor mount / frame stand combo...should make things abit easier!

Looking at the Promaxx Schocker 227 heads, seem like they might be good. Anyone used them?

May go with the Summit forged pistons, 6.125Ē rod combo. Lots of ideas floating around....

I would try to weld a flange that way you know it won't come undone over time.

George, My old Chevelle is long gone, and in the past 2 years there were no less than four temporary replacements.

Currently, a 2000 Trans Am...LQ4, 4L80E, Ford 9" rear...
Race weight is 4005#

WAS, a turbo car when I first got it, but like you have said, as a bracket car, it simply doesn't work.

I have since removed the turbo setup, swapped out the "turbo spec'd cam", and added longtube headers and a 3" single exhaust, back to a 2.5" dual outlet muffler

Anyway, I chose a simple, cheap camshaft...Elgin E-1940-P, aka the "Sloppy Stage 2" 228/230 585/585 112lsa

Torque converter is still a way too tight turbo spec'd triple disc that works good with nitrous, but horrible without..

Anyway, I have a basic combo, in a heavy car, with a wrong converter...lol

On a Mustang Dyno (supposedly reading 10-12% lower than a Dynojet), tuned by me, made 348/356 to the wheels, N/A...448/442 with a 150 shot, and 504/520 with a 200 shot.

Again, with the WRONG, too tight, converter, car goes 12.20's at 112-113 N/A, and has been 10.69 @ 126 with a 150 shot, carrying the front wheels. Good air would probably mean 10.50's with a small 150 shot...My Nitrous Outlet setup can make 400hp.

Not even taking into account, the ridiculous drivetrain losses I have (with a 4L80E, heavy triple disc lockup converter, steel driveshaft, and Ford rear with a Detroit Locker), I'm sure with CORRECT converter, and a proper launch, it would easily meet or likely beat your "mud motor" times, and the nitrous times already do quite easily.

I think you'll love it. Good Luck!

Thanks for chiming in Bob!
I wasnt sure what you were running, last I saw was the camaro.

Spent some time last night checking out stroker kits, piston / rod combos etc...got up this morning and decided to go with the Summit 2cc flattops for the stock rods. Got new arp bolts for them and will just run them with the stock crank after getting it balanced.

Machine shop is checking the 706 heads and with those should be able to get 11.5:1 compression. Or if we use the 317 heads 10.5:1. Hopefully we can get the compression up to mid 11ís either way. Still may return this cam and get the next size up.

I hope this will be worth the effort, it should have more power than the mud motor. My converter guy wants to go to an 8Ē, will run this first and see how it does.

Buddies Cutlass runs that Sloppy 2 cam. 12.20ís on no boost. Lowest boost was [email protected] Crazy!

Re: LS 6.0 swap

I have an LQ4/80E in my daily driver, it is a 2001 Silverado RCSS. 2004 LQ4/80E, small EPS cam - 214/220 .598/.604 111 LSA. Speed Engineering 1.75" LTs, they dump into 2.5" lead pipes with Dynomax race bullets - then a large case Magnaflow DI/SI with a 3.5" exit/tail pipe. 8.1L 32# injectors, 255lph Walbro, Nick Williams 92mm TB on a TBSS intake manifold. F-Body electric fans, Airraid intake tube, modded air box. Stock TC, 4.11 posi 8.6 10 bolt rear. It did 349/384 to the wheels on 87 octane swill. No idea what it runs, never raced it. My guess is somewhere around the 13.6 - 13.8 range. (Based on some races in "Mexico")

The next round of mods are 799 heads multi angle valve job & milled to 63cc, Transmission Specialties 2800 RPM converter, ported intake manifold, 160 degree thermostat, and switching to 93 octane. Hoping to pick up about 30 rw. It is a parts hauler, and tows my car trailers - 18' open and a 20' enclosed.

My 68 is getting a 2002 LQ4, Gen 4 rods and flat tops, sloppy stage 2 cam, 1.75" Speed Engineering LT's, 2.5" duals, 92mm TB, TBSS intake, 799 heads. Hoping that puts down close to 400 at the tires through an 80E and 12 bolt. Time will tell.

I am also swapping an LQ4/80E into my father's GMC Sierra. (Comp XR275 cam, bolt ons, 3200 stall) If you can't tell, I love the 6L/80E combo.

I thought about swapping to the gen 4 rods, but just decided this go around to use as much of what I already have and see how it runs.

I found Summit has their new line of forged ls pistons. Went with the .030 over 2cc flattops and they will work with either gen 3 or 4 rods. Gonna put the arp rod bolts in and have the assembly balanced. Mill the heads at least .030 and try to get the compression up mid 11ís.

Upgraded the trunions already and picked up the TFS 660 double springs.

Still thinking about going to a bigger cam....

Spray the heck out of it and see how it does.

Re: LS 6.0 swap

I got a great deal on the rods and pistons, otherwise was going to just leave it alone. Don't want to let the magic out...

I would skip the rod bolts on stock Gen 3 rods, JMHO. The 706 heads with the right cam will be the hot ticket.

...let the magic out. I have been hearing that often haha.

Stopped at Summit yesterday and returned the .551 lift cam for the .612 lift one.

Rod bolts were waiting on me when I got home. Flexplate kit came the other day. May or may not be the right one, seems to be conflicting info on that.

The 706 castings I have are the crack prone ones, they tested ok but donít really feel comfortable using them. Thinking the nitrous might hurt them?

Milling the 317ís for now. See how close to mid 11ís compression we can get. The 706ís would put it at 11.4.

Alternator, starter and power steering pump still need to come up with....and the msd box.

Getting alittle anxious to get this going.

Re: LS 6.0 swap

Yeah, those 706s are a gamble. I prefer using 862s, never had an issue with a set of those. Have you looked into ICT Billet for brackets? Great stuff, excellent prices.

I looked at a few sites at some different brackets. Will check them out too. Once it gets in the car will be able to see more what I need. It looks like the alternator would be pretty high in the stock location?

I just saw a buddies 5.3 setup in his blazer and he is using an electric water pump. Might look into that. Was planning on a new water pump anyway.

Started checking the fitment of the radiator yesterday. Looks like it will fit ok, not sure on the Windstar fans that I have. Man are they heavy! Look like they would fit ok with some trimming.

Oh...and late nite surfing on ebay last nite....GEN 4 rods are on the way.

Thanks Ron. Having a few issues here and there, but at least some forward movement. Did find out my 317 heads are cracked, but found three sets on my walk back from dropping my truck off this morning...most of my buddies are running them, so parts are pretty easy to come by.

Friends say it should run good. Hope so.
