i currently own a lh torana fitted with a 202 red motor.
i am lacking in the finer detailed info needed to build a solid engine.
i was wondering if anyone has some good ideas for some work to be carried out. i wanted to stay away from forced induction but still get as much reliable power as possibe
also i heard that the 202 blue running rear (elec. ignition, distributer, etc) can be fitted to a 202 block. is this true or am i being had on.
thanks for your help it is much appretiated.

Aaron
Here is specs for a good strong street engine that will develop lots of useful torque and still get good economy:
Red 202 block (with rope rear main seal).
Blue or black 202 crankshaft and rods.
186 or 179 head (or red 202 head with adjustab |

Go for a black head as well they are far superior to the red and even the Yella Terra is marginal depending who and what has been done to it. The black head requires different intake and exhaust but the factory EFI has stainless steel extractors that work

Also forgot Byrons blue crank and rods will go well the blue or black cranks are much nicer and the rods are a lot stronger.

I have been told on anumber of ocassions that although blue/ black heads develop slightly more power they have a habit of cracking near the valves but I have never actually seen this (maybe a question for Dr Terry)If you use blue motor rods ARP sells heav

Couple of problems John. VK extractors don't fit into a LH/LX without mods. The reason for suggesting to use the red head is so that the 186S inlet can be used. Unless you use triple dual chokes or the EFI manifold there is little point using a 12 port he |

Plus you will struggle to get a 202 to run on today's fuel with a small chamber head like a 149/161/173 head. You are better off using a 179/186/202 head (I'm talking high comp versions in cases where the low comp head is different). Building the motor Cr |
