Glock's new project: "Fred" w/ 5.3L LS swap info

[menace121978]

wonder what that pic was!

[Driveway Dreams]

Maybe it was the award winning Rooster from the other day.

[glock35ipsc]

You guys can't see it?? Hmmm, I still can. How 'bout this one?

[Driveway Dreams]

Nope, it says TINYPIC "This image or video has been moved or deleted." I bet its the rooster isn't it?

[glock35ipsc]

What rooster are you talking about??

Are you looking at it on your phone? I tried that and it shows the tiny pic thing too, but it's just fine on the laptop.

[lownfast]

Bob, those are some very nice numbers for a stock motor swap!!

I was looking at the ls6 cam but I've decided on the ASA cam that Gm offers
it's a torque cam with lots of overlap and really mean idle.

[Driveway Dreams]

No I am on the PC. And the Rooster was from a text the other day. Maybe I forget to send it after what happened the other day.

Edit: I checked with my phone just to see and it is the same there as well. I don't get it.

Hey Bob, wish I could have stayed longer, I came back when I was done working, but you guys were all done. I talked to Dave and he seemed impressed with the numbers, so am I! Thanks for telling me you were going over there, it was cool!

[nlped]

Congratulations on the great #'s. Once this crappy weather begins clearing up and I can finish the garage, I will be jumping on my install in "Bob".

The 95-up Vortec V-6 torque converter will stall at about 2400 rpm behind a V-8 and is as tough as GM made them for the 4L60E. It is really popular with the Impala SS guys and holds up behind their 4000 pound tanks so it should do fine in Fred too.

I ran one in my 95 Formula that made 340 hp to the wheels and beat the snot out of it on the track for over a year with no problems from the converter and mine was a used one out of a 130,000 mile S-10 Blazer that I got with the transmission at a pull-it-yourself wrecking yard for $50.

This converter should work great with the LS1 hot cam.

Don't give up on the 5.3 heads yet. Try the hot cam with the LS6 yellow springs and the Vortec V-6 stall converter first. You might be surprised at how much power they can build. If they are not enough for you then upgrade the heads with no money lost.

Congrats on the dyno run numbers. Fred sounds mean!

[rongstad]

Congrats on the numbers....

[fpjr0]

good number bob...

also want to say thanks to you and all the guys here that help with the many question I had,, as of today my truck is alive again.. it started on the first try....have a small leak on the return line and a small leak right at the transmission where the cooler lines come out...

I looked at both the ASA and the LS1 Hot Cam, but they both have a rougher idle than I want. I don't want to up the converter either. That is why I am looking to the 02 and up LS6 cam. In a 5.3 they idle like stock.

I was looking through some notes today and saw that I also had the Vinci Performance Ultra Torque and their 043 towing cam in my book as possibilities. They both have a little choppier idle than stock, but not too bad. And all 3 will work with a stock converter.

I'm glad you came by! Dave was pretty surprised at the first pulls too. I think we all were!

Sweet!!!!!! I'm happy to hear that it fired up right away. Do a good check of all liquid fittings, electrical connections. You are sure to find a few little things here and there. Congrats again!

[fpjr0]

thanks bob... I did check all fitting and wire connections they are all good.. the only reason the fuel is leaking is because the return line from the vette filter is a 5/16 hose and the return to my stock 84 tank is smaller than that... I tried double clamp it but didnt work... it looks like the 5/16 hose fits better in the one line that came from the canister for the evap stuff...? do you think I could just clamp it to that line instead?
and the trans lines I leaking at the clamp.. so I am just gonna order the right fittings....
bob how did you guys make the alternator charge... I guess I eliminated the plug that went to it and yes I got you on the a few things here and there...

[glock35ipsc]

On the alternator, if you eliminated the plug that went to it, that's probably the problem. I think it is the PCM that tells the alt when to charge, and when to shut off, kind of like the exciter (field) on the older alternators.

For the fuel, refresh my memory. Are you running an in-tank pump, or external?

[mcbassin]

Looks to me like you have plenty of ponies to the tires and tons of torque to play with! SWEET!

[fpjr0]

running an external pump and as mention b4 the line the came from the evap canister will fit more better and tighter than the actual return line,, so I was thinking on clampin the return to it and the original return line just pluged it....and I dont recall eliminating the plugs from the pcm to alternartor but I thinks it was already cut from when I bought engine.. I found some info on how to make it work with out the pcm thought.... thanks.. let me know your opinion on the fuel line dilema....

[glock35ipsc]

That might just work. Is that evap line mostly steel with short rubber ends? If so, and if you end up cutting the steel to get it the right length, be sure to flare the end of it a little to prevent the hose from being pushed off the end by the psi.

That's good news on the alternator, hopefully you can get it to work!

[fpjr0]

yes the evap line is steel and it has a T next to where I put my fuel pump... with short rubber hose as you said,... I am just gonna clamp it there,its flared.., will let you know how it turns out ....

I don't know if it has the CS-130 alternator or a newer version but it is probably the same control circuit wiring.

The L terminal on the CS-130 alternator is connected through an idiot light on the dash. It needs that resistance to function.

You can connect it to the alt warning lamp wire that was on the old 12si alternator in your truck or run a CS-130 pigtail harness from GM that they have with a resistor in the L terminal connection.

You can also get a courtesy light circuit out of a donor car and connect it through that too. I did it this way on an old Jaguar that I put an LT1 / 4L60 into to get the alternator to work since it didn't have an alternator warning lamp circuit to use. I left it under hood as a diagnostic tool to know the alternator was working.

[silvereagle07]

Are the 5.3 intake manifolds and the 6.0 manifolds the same? If so I've seen the guys over at tbssowners porting their intakes and getting 15-20rwhp. They were having it done by LSportworks. Here is a link.

[fpjr0]

68 tt,, thanks for the info... I been reading the schematics for the 80-87 trucks and I saw what you mentioned above,, the wire coming from the truck has the resistance built in .. so I am going to hook it to that and see if it works... thanks

bob sorry to keep hickjacking the thread... but not sorry about the total # of post in it..

[glock35ipsc]

No problem man! More info for the masses!

[bluex]

Ok its been three weeks and your not done with the trailing arm conversion yet??

WTF? You did the LS swap in a day???
