Got a 304 motor out of a Vp, obvious signs the motor has been played with. But just got afew questions!

-does the vp 304 come with a double row timing chain standard
-Also stamped on my bottom end crank is 308???? is this right, the block is a 304 block so has someone put a 308 crank in it or does is come with a 308 crank and have a smaller bore to make it the 304? anyone share some light on this???

The crank is still the same crank as used in the 308 - hence why 308 is cast into it.

The machining is what differs - theres enough meat in the raw cast crank, to allow the big ends to be machinced offset slightly closer to the mains, hence shortening the stroke by about 1mm.

Cheers,

Mick

Judge a successful man not on how he treats his peers, but on how he treats those less fortunate.

I believe it was when touring cars went to GroupA rules, so to compete with the same motors in under 5L class, they went from 308 to 304 cubes, which i think was 5.044 to 4.95 litres, or something like that.
