I have used both Lokar shifter setups. One is a cable style and I did not like it that much, was a PITA to set up. I am now using the rod style but it is limited, I can only go to 3rd gear with that shifter b/c of the angles just wont allow it.

As for what a company will do for you, why not contact them to find out!? that is the best source of info.

Puglia10 · 07-09-2010, 11:33 AM

also, if the motor i get just has harness/pcm and altenator, am i screwed with no power steering pump? what else am i going to need?

low_84_inchaska · 08-16-2010, 11:35 AM

I have a question on the 5.3 truck motor.

is the alternator, ps pump, water pump, starter and brackets the same for the 1999 and on motors....say will accessories off a 04 work on a 99?

thanks,

jason

Thanks for the info. just got a 5.3 vortec with 50k miles for 500$. im putting it in my daily driver, may the carb and my knowledge for it go straight to hell. Vegas heat sucks for the performance.

I'm sure this has been covered in another thread, but here's a reminder about oil pressure and water temp fittings. The metric-to-npt fittings are available at speedwaymotors.com. They might be found cheaper somewhere, but they shipped quick and fit perfect:

I've got a set of LS Cats if someone is interested.

sdwolff98 · 02-16-2011, 08:53 PM

1973-1974 was when they started installing cats on vehicles right during the gas crunch era. In texas and I got this from the DMV if it was not installed as a factory item it does not need to be present on the vehicle at the time of inspection. So if it is 78 for sure or newer at least one set of cats has to be in place on the vehicle. Went through this with the inspections station on my pontiac firebird. They did check to make sure that all required vacum lines were in place on the engine. What few there were lol. Working on getting that car back through inspection for the year having some brake issues that are holding me back atm. Sean

sdwolff98 · 02-18-2011, 09:46 AM

I was reading your other posts on the engine. you say you smell strong odors of fuel? is that when you are trying to start the engine? if so have you tried to find out where it is coming from at all? if it is leaking from the rail or injectors might also explain the no start issue as well.

Wolff, not leaking fuel anywhere checked everywhere, nothing the smell is mostly after i've tryed to start it....i checked my oil, doesnt seem like gas but i have extra oil now....so i think gas is just passing by the injectors gonna drain oil, put in new...my friend has the "noids" to check the injecters, try that tonight and oil pressure is still a big question mark....at the sharder valve, it seems pretty good visually...& the wire harness is the stock on outta the van, with improvements thx in advance

Shon · 02-16-2011, 01:44 PM

is that for visual inspection!?!? why would these old trucks go thru a visual inpsection? sorry, in SC we do not have inspections right now...

yes, its hit and miss around here (ETX), some places dont, some do depending on where you go but it is getting worse and worse. 24+ year old vehicles do not have to undergo the sniffer, but a "visual exhaust/emission equipment" inspection for anything newer than 1968.

actually maybe it was 1975. somewhere in that time frame, i dont know when they started installing them.

68GMCCustom · 02-17-2011, 10:17 AM

wasn't it the 1975 models? At least for GM?

low_84_inchaska · 02-17-2011, 12:02 PM

what about throttle cable setups.....1999 5.3 in 84 shorty??

sdwolff98 · 02-17-2011, 12:14 PM

68 custom,
You might be right IO know it was within that times range.

Cable setups for a 5.3 you will probably need an 04 or earlier engine unless you want to piece it together I know lokar and a couple of other companies make cable setups for that and ls series engines. I have one for an unused tpi conversion atm. Let me look around I might have the ls lokar setup laying around somewhere.

low_84_inchaska · 02-17-2011, 12:38 PM

yeah my motor is a 99

sdwolff98 · 02-18-2011, 10:18 AM

hmm strong smell of gas during starting attempts. starts with starter fluid. let me ask a mechanic friend of mine and see what he says to check next. hmmm interesting problem the vats disable I am guessing?
