I'm not very up to speed on the conversions.

I know that a 427cui a la Cobra is a 7ltr ? V8

Is the 427cui considered to be a big block or a small block? What is an 8ltr is that 500cui?

Could it be due to short stroke v long stroke? Or oversquare blocks?

Given the responses so far about same size small block but increased stroke (is it increased piston diameter at all?) clearly the same can be done to the big block in which case what is the biggest big block available today & what is the biggest big block available in all time?


Finally does the fact that the small bock can be increased to x cui mean that essentially the big block will soon be extinct? Like for like i.e. say a 396cui big block vs a 396cui small block power wise?

That last post has just raised another question.... what is a Hemi?


Also are all the V8's pushrod? I recall reading something along these lines and it still amazes me that the vette C7 is like that.

Wow - without the OHC/DOHC those V8's are very compact.

In the UK If I wanted a Corvette - fairly modern - what sort of prices are they 2nd hand? And what power & finally what MPG/6th @70mph - or top gear @70mph?

I recall following a C5?? at M4 J8/9 towards High Wycombe - Me in 3rd at 60mph coming off the round a bout him in front he nails it me too - all the way in 3rd & 4th the noise of the V8 was very very nice and the smell of slightly unburnt fuel & the heat from it was great (only draw back was either he wasnt giving it everything - or my expectations at how much faster/gaining ground over mie at those speeds it would be (it was a red one BTW)

Therefore using the FIA conversion my 2ltr turbo is N/A 2.0x1.73 = 3.46ltrs for racing regs which in turn is 207ci.

How about a nice 997cc Fiat Panda... that would equate to ...60Ci!!!
