5.0 Litre Conversion

[robrover]

Anyone fitted one of V8Developments advertised Performance 5.0 litre short engines? Come with stroked crank, H beam rods and pocketed pistons. Claimed to be stronger than TVR's 5.0. Although it doesn't explicitly say so on their webpage, I presume as the bore is increased that the blocks are also top hatted with flanged liners?

Any other reputable 5.0 litre performance conversions around?

My current 4.5 block may be destined for a Disco so need something to replace it with.

Cheers

Not trying to teach a granny etc. but a 5 litre block with std 4.0 or 4.5 heads will be seriously strangled at the top end. I'd regard what most builders refer to as a 'stage 3' head as a minimum for this capacity in a sports car.

Personally, I'd put a 5 litre with the stock heads in the Rangie and some serious heads on the 4.6 in the TVR...

Have you got a dyno sheet to prove it?

Looks like that door shut could do with some attention at the bottom

[SILICONE KID]

Yes your right ..not got a clue how to do that..It is TVR not a swiss watchThe door sits about 1/4" to low at that end but it sits flush..

You need a different wheel size at the back to get the door adjusted

Mine was the same, you need to pack out the top hinge with another shim (they are ali and easy to knock up DIY)

It's a fiddle to access the hinge bolts and you have to mess about with the catch a bit after

[SILICONE KID]

Thats why i have left it alone,I don`t want a car with one doorYes i now have 16" on the front so the 17" are spare..

I'm not using Rover/TVR heads. 1964 aluminium Buick 300, 1.75 inlets/1.5 exhausts ported and flow benched to support a potential 410 bhp, combustion chambers welded to 38cc, Buick 300 tin gaskets.

Ahh, that should do it...
