hi guys, im new to this, im a new owner of a 72 240z, i bought it for 800 bucks, i was just wanting to ask about the engine on this car see if you can give me info on what you think of it, the engine it has a f54 block and a p90 head from a turbo 280zx, its pretty fast and does not burn oil at all, now i was wondering if this a good combination or should i change to a different kind of block? thanks!

 

cool, so low compression , high compresion? which is better?

thanks alot !
