TVR Parts conrods

[spitfire4v8]

A copy and paste on here from the Al Melling facebook page suggests that the missing big end oil grooves and relative lack of big end cap thickness is a major mistake.

However, these conrods must have been used on some / many of the Racing Green FFF full engine rebuilds ..

so the question is : is anyone running the TVR Parts conrods and if so have you had any issues / would you wholeheartedly recommend them ?

• oil grooves could always be machined into the rods afterwards anyway I guess .. ? but big end cap thickness is rather harder to rectify of course!

Are you using high revs .. it's shutting the throttle at high revs that usually breaks rods on the end of a long race straight for example .. rods don't normally break due to forced induction if the revs aren't any higher than normal.

I want to build a high rev 4 litre - the sp6 has a peaky power delivery so to maximise the use of the power you really need to be able to rev it high to drop into a useful power band in the next gear.
