PS. Here's a picture of my V8 in situ in my +4, which is also an inch higher than the original book chassis. There's plenty of room, so
I'm sure it would be doable in a chassis only 2" narrower.
 
Wheels on for the first time

V8 it you can get one for good money.
chevy V8 would be way to heavy tho it isnt really all that big, we have one in are boat
but since its a RV8 which isnt that heavy go for it i say

Thanks guys you've all been a lot of help.
Think it's gonna be the V8 just gotta check on box and dif and I'm away.
Hopefully there won't be many stupid questions during my build
Cheers

Standard 7" Sierra diff will be fine, although an LSD would probably be a good idea with all that torque.
As for gearbox, LT77 as used in the SD1 is by far the easiest option. A better but more expensive choice is the Borg Warner T5 as used in the 2wd
Sierra Cosworth, TVRs and lots of US Ford applications. That's what I'm going with.

Have to throw this one into the mix.
How about chevy LS1 more compact and ally and 350 BHP out of the crate.
Just not locost but could be a substantial saving over tuning a Rover motor past 250 BHP!!!
I've seen this motor up close and its perfect.

Just a small question.
Has anybody thought of using a Jag back end as opposed to the sierra IRS.
Or has someone already done it

Reason I asked is I was told that the Jag rear is good for up to 500 BHP

Ever tried to lift a Jag rear axle assembly, the weight is truly massive.
Often forgotten that everything on a V8 car has to be be bigger and heavier, exhausts (x2), starter, battery, fuel tank.
Although light and tough the Rover-Buick V8 is a bit laughable by modern power output standards and it is expensive to tune, a 200 bhp k series or
Zetec can be built for less than it costs to exceed that kind of output from a Rover-Buick V8.

Having posted this thread a couple of days ago I was thinking of going with the V8.
However having done some more research into power to weight etc I'm leaning back towards the zetec. Initially the actual engine is gonna cost
more as it's a new unit but cuts out all the hassle of finding a new box and diff and overall the car will be a lighter easier build.
Just shows it always helps to plan ahead!

Have you thought about an XE? Cost of fitting is similar to a Zetec (if starting from scratch) and the power is much better as standard (NS Dev got
around 200bhp out of the box on standard cams and head IIRC, Zetec needs cams and head work to get there)
Alternative a Duratec is a very nice engine for more money, similar power as the XE, but all aluminium.

That'd be me
But I'm only gonna use the diff (47 kgs, against 27kgs for the Sierra).
The other reasons besides the monumental torque is it's LSD and 2.88:1 f/d ratio, and they're dirt cheap compared to Sierra 3.14 (which
you need).
As for R V8 (and turbos/intercoolers) in a +4" chassis
Go for it, you know it makes sense.
