Re: LS engine swap info
Whats this lokar shifter cable i hear about? you cant just put a lq4/4l80e and be good? how much is it?
also, has anyone tried blackbear for tuning? what do you do, just send them your pcm and harness? will they do a performance tune for the same price instead of a stock tune?

Re: LS engine swap info
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:

Re: LS engine swap info
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

Re: LS engine swap info
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.

Re: LS engine swap info
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

Re: LS engine swap info
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.

Re: LS engine swap info
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. Sean
