New to all this, need some help .........

[Sunbeam Fanatic]

Hi all

Stick with me, I'm from over the pond and am usually only used to dealing with 4 pots!

So I'm building my first Hot Rod out of a 1968 Rover P5B Coupe and it usually runs the Buick derived Rover V8 and auto transmission.

I'm going to keep the inside/outside fairly stock but have decided on using an LSx engine, but I haven't decided which type yet .....

And so we get to the first questions:

Am I right that some LSx engines had alloy blocks (as this is my preference)?
If they did which ones (so I know what to look for when buying)?
What's the difference between LT and LS?
Why would you choose an LS1 over an LS2 or LSwhatever?

I need to choose the base engine first then I may need some help on that specific type (re-building, tuning etc.)

All advice gratefully received.

Cheers,

SF

Here's a start, mostly basic info though:

Ls-2 would be my quick pick for you......
Yes it has a alum. block and it also has a bigger displacement 6.0 instead of 5.7 which will help you with all your weight.
LT-1's are so out dated and weren't the best design in my opion so I wouldn't even think about wasting my time on that conversion.
Hop I helped with my 2 cents.
