TVR 5 litre engine
Discussion
Get input from Spend, Dom at Powers or JE about cross bolting and get a different perspective. You'll understand that it isn't that crucial. Good balance of the complete assembly is though. The difference between the large journal vs small journal crank has also created some debate, as to whether it is more important to have the extra 'meat' on the crank or in the block. Again, a lot of this will depend on how much power and torque you will be putting through it.
As hinted at above, I am led to believe that the TVR 5 litre engine was externally balanced, thus leaving it exposed to the risk of breaking the crank under pressure.
V8 Developments internally balance their engines, reducing the risk substantially. There are quite a number of V8D 5 litre engines out there

^^^^ This.
A genuine question regarding the above reply for someone who is not very text/symbol savvy,.....does it mean 'I agree',or is it slightly more rude,I've searched online but come up blank.May be worth noting that many 500s, (but apparently not all?), could be modified and cross bolted; dependent on the mains caps.
I have seen multiple opinions on the benefits vs cost vs disadvantages to doing this however.
It is pretty much universally accepted that full internal balancing is more critical.
I would say essential IMO.

Mine is late '97 first registered January '98 and was not cross bolted

Well look at it another way - my 500 is 20 years old - it gets driven hard & has been totally reliable to date. While I'm sure cross bolting has its benefits the 500 engine isn't going to melt but is a subject the 450 owners like to extol frequently while I enjoy the higher output.....
