Hi

It appears on the disc as having been fitted to an Adelaide XU-1 completed 2/2/73 L229143 which was sold by Reg Hunt Rhodes of Elsternwick Vic.

The dizzy is a standard 202 type as is the head.

Cheers

Bazza

It looks like it has a low comp 202 head- same as fitted to gtr but obviously not XU1 head.

2811930 is a low comp 138 & 173 head which is used on both high and low comp 202. Only the pistons fitted in the 202 determine if the engine is high or low comp. Hence the only way to visually identify an untouched factory original high or low comp 202 is by the engine number prefix. QM & JM are low comp, QL & JL are high comp.

Yes you are correct, sorry for that...I think my jibbered engwish is the problem and re-reading my post i can see how my writing can be interpreted... it is a low comp head (or is it best referred to as open chamber?), which was fitted to 202s, not specifically a low comp 202 head. I think a comma could have helped.

I know the LJ GTRs also used these heads and many incorrectly think that it was specific to the GTRs, without realising that its head common to a number of engines.

Starting to strip and clean the JP and found a second block cast number behind the oil filter this side has a 5 whilst the exhaust side has the 2, more food for thought 👍

Hi Ian,

Both my XU1s are early 72 cars so they will be miles away from yours. Also both are Adelaide build cars. Both engines start with JP10**** and both are long gone unfortunately
