patbull, the speedhound plate for z-bar doesn't work with the LS2 block. I tried. I ended up making my own, but later found my design made very similar by street and performance.. their website is lousy though, so i can't find the part # - haven't seen it since the one time i happened upon it by accident.

I am only just starting to look into this conversion, I decided on it about a week ago, sold my current engine off and have begun browsing websites prowling for a engine (i figure thats a great place to start)

Does anyone have preference over engines?... I will be completing this on a budget but still want the best equipment I can get for my $$$

I was going to settle for a nice little LS1 5.7L (or Gen III ) but have been told they had bad piston slap and the faults were designed out of them when they released the LS2 6.0L. Does anyone here feel the extra money is worth the LS2?...

Appreciate your time, I would imagine i will be back here at every new stage of my conversion! haha.

This Thread is great help for a simpleton such as myself in this area!! haha

Depends on your budget - buy as new an engine as you can afford or are willing to spend. An LS2 is generally more desirable than an LS1 because they're newer, they start out with more power, and have been refined - but you're generally talking a lot more money too, in-proportionately so in most cases vs the benefit.

LS1's can have piston slap, but not all of them do. The ones that do generally don't have any other problems with it. Mine makes a little (very little) noise when it's cold but goes away quickly as it warms up - sounds like one piston. It has 70k miles and runs absolutely great, doesn't leak, doesn't smoke, runs like a new engine. These engines are known to commonly go 200k easily.

Some of the early LS1's had some oiling issues under extreme conditions, but I think actual problems that arise from this are rare. I believe you can also get updated parts that are not that big a deal to install if it concerns you. If you are going to be routinely spinning the engine up really tight, invest in some aftermarket rod bolts.

It's recommended to get the newest LS1 you can. I got a 2002 for my setup, it has the improved LS6 block, the latest PCM, an LS6 intake, etc. - look carefully at 01 & 02's though if you want the LS6 block, from what I understand not all of them have it. The 98 PCM is undesirable if I remember right.

All in all the LS1 is a well designed engine that doesn't really have any significant inherent problems.

If you're looking for bang for the buck & don't necessarily care about having an aluminum block, pick up a six liter truck engine as a base. Throw an LS6 intake on it, or spend a bit more money and pick up a set of L92 heads, intake, tb, and injector package for less than a set of aftermarket LS1 heads - throw in a reasonable cam and you're approaching 500hp fairly inexpensively & reliably...

I'm hoping to do it mostly myself and on a bit of a budget. But at the same time I don't want to have any probs down the track from inferior fit and finish etc...

at this point I think I'm going to shell out on some "Speedhound" plates and mounts. then I'll start searching the junk Yards for a engine and see what I come up with. But I definatley want the 4L60E or 65E to go behind it.

thanks for the info on the LS1. It will certainly be kept in mind when considering my spend on an engine.

Cheers

Don't rule out the "standard" non-setback adapters like the ones from Vetteworks. In my install (also 4L60E), I tried both and the standard ones fit better everywhere than the 1" setbacks did.

I think the primary advantage to the speedhound adapters is that the stock z-bar setup can be used if you run an original manual tranny with the LS & the speedhound/melrose conversion headers.

No offense or anything, but the whole point of this thread was to be a directory. It was started so people could just scroll through and see build specs of individuals who have completed LS swaps. Can we please keep discussions out of this thread? Thanks.

Agreed, MODERATOR delete the Q&A posts please. The posters got their answers. Let's keep this thread simple and useful.

SUPERPOWERS

Also agree. There is a thread for questions and it is listed in the original post.

I installed my ls1 in my 75 c3 and I am unable to fit my coil pack on my passenger side valve cover because the engine sits back and my heater box is in the way. i am wondering what others out there have done, I would really like to keep the heater box in the car and use the stock coil set up.

DaveC3R

Hey MTC...
I deleted my heaterbox and installed a Vintage Air system under the dash, saved a lot of engine room real estate. But if your stuff is working well, I understand why you wouldn't want to go this route. There are a number of manufacturers that make coil relocation kits.

Here are a couple...
