Hi Everyone,
I am a rodding virgin...so please be gentle.
I have just entered the money sinkhole and am embarking on my first project. As bizzare as it may seem I want to rod a 48 Morris E. My engine/trans of choice is the Holden V6/auto because of abundance and simplicity. (and it will fit)
I was speaking to someone on this the other day and they commented on the fact that this may not be the best choice as there could be some issues with the computer freaking out because of the change in things like weight, diff ratios, etc.
Did he have a point or was he another 'armchair expert'? I thought the computer took it's signals from the engine/trans and adjusted things accordingly..

I have been reading this forum over the last couple of weeks and I must say I am impressed with the level of knowledge out there and the fact that it is given out so freely!! Thanks.....

The commodore V6 from VN onwards used the GM Delco 808 computer and variants. Lucky for us, this is the only factory computer that can be fully re-programmed. The software to do this is called Kalmaker. If you want to learn more about EMS, EFI and Kalmaker, then you should.....

(......c'mon everybody, what should Cheech Wizard do?)

.........just bolt it all in and drive it!
Lowering the ratio of the diff to compensate for any increase in tyre size would also be a good idea as the standard VN is doing about 1800 RPM at 100kmh and going to an effectively taller ratio by way of tyre size might make it a bit of a slug in top gear.
For example a standard 3.08 ratio and approx. 25" tall tyre will be roughly equal to a 3.70 ratio and 30" tall tyres.

If you transplant the whole drive train or at least retain close to the original rear ratio I can't see why it wouldn't go well...The Morry should go like the clappers...Later down the track you could put in the supercharged version, then you'd have to keep it from taking off

Thanks everybody for your input. I may be a virgin...but having read the forum for awhile I too recognised Choco's plug.
I look forward to sponging off (I mean gleaning useful information) from everyone on this forum. And I hope to have the pleasure of meeting you all sometime.

The book I'm referring to is the Electronic Engine Management Reference Manual. There are two others:
The SBC Tuned Port Injection system
The Auto Electronic Reference Manual

My web site has details on all the books, but in Cheech Wizard's instance, the EEM manual is the one I would recommend. And for all you animals poised over your keyboards to chastise me for spamming and/or self promotion, I get about $1 per book in royalties.

That's OK Choco...
I'm happy to donate a couple of bucks towards your cause for your books. It's got to be cheaper than paying the going rate in a shop and then still not know what's going on!!!

Now thats alot of books that need to be sold before you even recover your time Choco, let alone all your knowledge youve built up on the subject.
So where does all the $$ go? Have you ever been given a breakdown?

Yep. That's between me and the publisher. I assure you, it's not cheap to publish books that are going to be sold on an international market. The publisher takes all the financial risk by putting up the money for printing, distribution, advertising, marketting, etc for the life of the book, and what's left over is divvied up between the author and the publisher at an agreed split. It's a pittance (for both of us), but I am still getting royalties for my first book, which was published in 1993. Now I get three pittances every quarter.
I write the books because I enjoy it, not because I want to earn a living out of it.
