Hi guys,

I just bought my motor. It's in great shape. It is an all-alloy 5.7 litre with a rebuilt bottom end and CNC ported heads. It has a hot cam, high flow intake, fuel rails and oil pump.

It's going inside my 1967 Chevy Impala two door hardtop. The car itself is also in good shape. Most of the body work has been taken care of and the project is progressing at a good pace.

As I just bought the motor I have a few questions.

1) The guy I bought it from says it has a GTO oil pan will that fit inside the engine bay or is it better to go with an after market oil pan like the Holley LS oil pan?

2) He's selling it with a delphi MEFI ECU and harness. Will that ECU also be able to operate the gearbox if I end up buying a 4L60E?

I'm sure I will have a number of different questions. Thanks in advance for your help.

Glad to see more B-Bodies joining the LS club!

The GTO pan is a front sump, and it will hit the crossmember. You will need to get a more traditional rear sump pan. The Holley pan is a good choice. It's a little pricey but it's nice and shallow.

As for the harness question...I can't really answer. Someone else will though.

Thanks Dave. I'll look into the Holley pan. That's a nice looking 1965 Impala project you've got going on!

The Delphi MEFI ecm is for marine applications, I believe. It's a rather crude ECM that operates in batch fire and does not have transmission controls. You'd be better off with an LS1-style PCM.

Thanks! But actually the pic in my signature isn't my car...just one I Photoshopped a bit to make it into what I want mine to look like. If you haven't seen it already, see my build thread here: https://ls1tech.com/forums/conversio...-5-3-swap.html

'65-'70 all have the same frame so a lot of the issues I had to overcome will come up in your build as well. If you need any help just let me know

Jono1982

To be honest... I'm a long time reader... First time writer. I've been following your build and there are some really cool things you've used on your project in particular the dash. I'll probably be hitting you up for advice somewhere down the line!

Jono1982

Thanks. Any suggestions on an affordable ECU for a road going car? I just had a look at the Holley and FAST ones and they are $1500ish...? The engine has actually come out of an off road vehicle that's why the computer is a basic one I guess. He just upgraded to an LS3 and offloaded the LS1 for a good price.

I would suggest getting the stock PCM for the engine. You could use the harness and ECM he has, but it won't have transmission control.

Jono1982

Thanks. I think I'll go down that path.

Hi Jono, its hashim, I thought ill reply to your email here to get the forum's opinion since we are both new to this

How much did you get the engine for?

Im going with autokraft pan and dirty dingo sliding engine mounts which gives me all the adjustably i need. For harness and ECM, im going with PSI with a pre tuned ECM. All plug and play to avoid the hastle

Hi Hashim. Thanks for the lead on the PCM and Harness I'll probably end up ordering from them! I bought some adjustable mounts yesterday. I'll see how well they work when they arrive in the mail.

I got the motor for a steal. I'll tell you about it when it arrives at the shop.

spitfire980

Did you get the engine mounts from dirty dingo?

Jono1982

Engine has been delivered...

Jono1982

Motor mounts arrived in the mail. I bought some off ebay. They are three position ones. I also found a wreckers who will sell me a gearbox, starter motor and a few other parts that I'm missing from the GM family.

I've changed jobs this week and the new position is very close to the garage where the car is located, so I'm sure things will start to progress faster.
