Don't need to change valve guides.

Enginetech in USA makes some very nice umbrella valve steam seals you can use on early RV8 valve guide.

There is an error on V5. One letter is wrong. It is a problem here for customs and registration. I think DVLA can ...

Several points to rev :
1) rod/stroke ratio
2) weight of rods/pistons
3) valve train weight and stability at high rev
4) bore/heads (big deal on RV8 because heads strangle engine breathing upper 6500 rpm )

It is an Yankee Myths you need billet crank for race application. With short stroke SG crank does the job. You don't need just to swap part for stronger but you need to concieve the engine for high rev. I have a this time two 4.5 engines : one clubman and one race. Internal combo is completly differ...

The max safe revs on the engine for continuous race use is 6500 which limits the differential ratio to a 3.3. Sorry to say that..... but it is just Sir Eales who do...

Hi,

If you offset your 4.6 crank to 3.4 stroke, you can use SBC 5.85" small journal rods with SBC 305 pistons.

If your block has been flanged with Westwood T-liners O.D. 99.1mm you can bore it up 96.5mm.

Cheers

In fact, it depends of which 5.0 you intend to use. Factory TVR 500 engine ?

For spark plug, ordinary NGKs make great job.
