rover v8 cr

[Graham]

im just putting together a 4.6 from some old range rover bits to drop in my chim, now the stock cr on a rangy 4.6 is only 9.35:1 so i need to jack it up abit, so am going to get the block decked a little. what cr is it safe to run a road engine at, and what was the stock tvr cr


im using p38 heads as a starting point and also stock 4.6+20 pistons

The simple tested way is to put 4.0 pistons on the 4.6 rods to raise the comp.

ive been trying to find some 4.tr + 20 pistons but not found any at the right price yet. 4.6 i can get for around 200 quid.

it would be a much easier way of doing things, no decking the block and the inlet... do you know what cr that brings out.
