To LS7 or not

[400TT]

The LS7 is an iconic engine, a true race engine for the street. And the sound.

The LS7 will be perfectly streetable and provide great bragging rights.

Mike is right any of the Gen IV Chev/Holdens will provide plenty of mumbo for a Cobra.

Get some advice on the diff and you don't want any weak links. What gearbox are you thinking of using?

Craig,

At the moment I am thinking 5 speed, T56 or something similar, but have to admit that I know nothing about the TKO variety of gearboxes that I see a few people have.

Will come down to what will best suit engine I think, but then I have to decide on engine, either LS7 or LS3???????

Thanks for feedback.

Does anyone know much about the Factory Five rear end that can be put into a Harrison!.

Cheers

Hi Lawrence,

We'll I'm clearly biased as I went through the same thought processes and chose to go with an LS7 because of the magical 427ci and I'm very pleased I did...the 1st time I heard the engine start was just amazing...

I hear the argument about too much hp and I think the argument is very valid...my stock standard LS7 crate motor produces around 440 hp at the wheels and I think that's more than enough (certainly for me!)...

I think if it's practicality that rules you, then any of the LS engines will make more than enough hp and they will all do a beautiful job...but there's something about the illogical and slightly extreme side of going for the 427ci that just seems to work for a Cobra....after all if practicality was everything...would we be wanting a cobra in the 1st place??

Good luck with your deliberations...

Regards.....Paul

Very interesting debate.

The 427 is appealing because I guess of its numeric link to the Cobra, but as stated, more than enough power can be sourced from the previous LSX versions with limited mods.

What is the ball park figure to source a 427 crate donk?

"Go Pluck A Chook" .. I'm still trying to catch my breath from laughing so hard on that one.

OH man ! Does that hurt !!

That was good Rob.
Sorry guys but it just hit my funny ... I guess because he was a chicken farmer.
I love the LS series engines. I am impressed with the common sense approach to the horsepower delimma on this thread. Mike has it right in my opinion.

Still trying to get my composure.
