Hi all I am in the next week or so getting a p5 rover 3.5ltr. I intend to fit a chevy 5.7 v8, has anyone done this mod before or similar and if so what transmission did they use. I dont mean to upset the purists but i thought id try this forum first. Also has anyone fitted a retro fit air con system?
Many thanks
Len

If you're going to replace the Rover alloy V8 with a cast iron GM unit you may want to get hold of the 3 litre torsion bars as the weight factor is significantly different. They are not the same although they appear to be so...and it's more than just a slight adjustment issue at the rear bellcrank. (I've done this in reverse...cast iron engine block to alloy engine block)
Scott Richmond in OZ fitted a Chevy V8 to a P5 many years ago and towed caravans and the like with it. I saw it once and although legally engineered and very functional, it wasn't a refined/well sorted piece of engineering.

Re AC - pretty much all the P5s over here in Australia have been fitted with AC, including my 3 litre.

Ive seen winstons car and its got coilovers on the front in place of the original shocks. Now i didnt see whether it was running torsion bars as well as the coilovers, they may have been fitted to counter the extra weight.

The Torsion Bars are all the same Vince the Torsion Bar Adjuster Levers (Bell Crank) are different for every Model Mk1, Mk3, and P5b have high and low versions

I wish someone had told me that 25 years ago John! None of the experts in OZ at the time seemed to know that! I was told that it was just an adjustment on the bellcrank. From real world experience I can definitely assure you (and anyone doing an engine swap) that there's definitely not enough adjustment to counteract a 4" lift in the front end when going from a cast iron 3 litre block (Weslake) to a fully alloy P76 engine. I now have a set of P5B bellcranks (stashed in a box) but they don't look much different to my MK3 versions, although I haven't had them side by side to check for any angle variations.
For what it's worth, unless someone has definitive drawings of the variations in bellcrank angles of the P5 model range, it would be a useful resource to identify these. I'm happy to start this with my P5B bellcranks on a separate, fresh topic. What do you think?

I just got the PB out Vince to check! the part numbers are raised on them Mk3 standard and low suspension (also Mk1 and Mk1a and Mk2 with high suspension) RH 500245 LH 500244, P5b standard and high suspension (also Mk2 std suspension) RH 514181 LH 514180 I knew there were differences in the adjuster but the torsions are the same RH 507290 LH 507289 I will leave the the post as they are sort of relative

Then the spring rates are all the same. That accounts for variations in the ride quality across the P5 range! I'd still like to see all the various bell cranks in an even row to compare the angle differences.
NB. To get the front of my car to a desired ride height, I hot torched one leaf in each spring pack at either end, then allowed the car to drop to a predetermined level on spacers fitted on each bump stop. When they cooled, the 'hot torched' springs were removed, professionally retempered and refitted. I fabricated clamping bands at either end to contain the pack. So the front suspension probably works on 5 of the 6 leaves of the bundle with the 6th providing lesser assistance. As a consequence the spring rate on my car is probably softer for the light alloy V8 than most.

My AC was dealer fitted in 1963. It has a Lucas head unit mounted in the middle of the front parcel shelf, with part of the shelf cut away. There are more compact units around. The drier and compressor are simply what you can fit in the available space, plus inevitably a custom bracket to mount the compressor. Sorry I cannot be more precise, but it is no good tellign you to get a compressor off a 2001 Holden Commodore as a) it is probably not available and b) mine is a 3-litre anyway. This is the kind of thing you are looking for: evaporator.

Hi what air con system did you use? Do you have a list of parts used?
Thanks
