Ok, so I'm going backwards. My EH has a 202 in it backed by a Trimatic and I have the option of picking up a 179 which has a knock to it. Other than working out how much I should offer for it, can I adapt it to suit the existing Trimatic (still set to column shift) and will I need to change the Tri's mounts (or the 179s for that matter)?
The 202 is a fuel guzzling sieve that leaks oil at a new spot every time I plug an old leak so one way or another I'm going to be up for an engine rebuild.
I may have this wrong, but I was led to believe you can use a 179 block with a blue/black head and the Commode EFI setup. If so, I figure that would almost be my best option. The other thought is to keep the 179 99% standard except for extractors (will my old 202 ones fit a 179 head?) and a Webber dual-throat carb/manifold.
The car is a cruiser, nothing more so after looking at RB30 and V6 options I figured the 179 could almost be the best option - I'm still musing it but keeping the motor to math the badge on the boot appeals :) |

Hi Pete. All Holden Red blocks are interchangeable, the Trimatic will be a bolt up fit to any of them.
How much for a 179 with a knock? Personally, not much, unless it is a virgin block, (i.e. not been bored) & suitable for a rebuild.
Maybe a gasket set might sort the 202 oil leaks.
A blue/black 12 port head can be fitted to any Red block. A modification to the block is required. Four water gallery holes need to be drilled into the deck to allow water to flow through the slightly different design in the blue/black head. Very easy, use the blue/black head gasket as a guide & drill the holes. Once done, the head fits up as per any Holden 6 head.
Extractors, if to suit a Red 9 port head, they will fit any Red head. 12 port blue/black are a slightly different design & will only suit blue/black 12 port head.
I completed a Red block with blue 12 port head & injection in November. Works well. There are many things to consider if going injection. Getting the manifold on is only the beginning. Fuel system & return fuel line is required to suit the injection, among other things. |

Cheers mate. If I can bolt it up to the Trimatic I'll be happy - the less hassles the better :)
Am I right in assuming that I'd need aftermarket computer to go with a 179 displacement (rather than 202), surge tank, fuel return, high-pressure (EFI) fuel pump, and wiring loom custom made/spliced into the EH loom plus the head/EFI manifold? Plus catalytic converter (02 sensor if the setup uses one?). I'm just trying to work out how much I'm going to have to budget on this if I go down this path.
Did you see any improvement in economy? Reliability has rarely been an issue with the 202, other than blowing a head gasket and leaking oil everywhere so I'm more interested in a smooth running motor that is cheaper than the 202 to run (it really is a fuel guzzler :D )
Cheers

Factory Commodore computer is what you use.
Fuel system will require a return line as system requires a loop of fuel at pressure, constantly feeding.
There are are 2 ways to tackle the problem.
Internal fuel pump, I used a VT Commodore pump. Tank needed modifying & pump needed a little modifying too.
External fuel pump, you will need a lift pump & a high pressure EFI pump, & also a swirl pot canister.
Wiring loom is a case of knowing what needs adapting into the EH loom & sorting it out.
Obviously, the EFI manifold, throttle body, air mass meter, EFI ECU (computer), all factory wiring between motor & computer to then remove what is needed.
No catalytic converter or 02 sensor if fitting to an EH.
Ecomony improvements, it's been so long since I had a red of any sort to know if my economy is reasonable. Theoretically, it should be better than a carby on the same motor. Will do a check in the near future to work out how it goes. It has better economy than my ute!
202's have generally been a tad heavy on fuel. But then they tended to be fitted to the heavy cars in the 70's.
The complete Black motor with all EFI components cost me $110. Removed all bits I needed & dumped block. Recoed the head which was only a couple of hundred. Fuel delivery system, new VT fuel pump, modified fuel gauge sender unit, machining an adaption ring to weld into EH tank & return fuel line could total $1000+ depending how much you can do yourself. External pump may be a tad cheaper. Little bits add up to quite an amount too. Head gasket, accelerator cable, relays, fuel shut off timer, injector cleaning, VK distributor rebuild, leads, etc., air filter pod, extractors, etc, etc. Realistically, in the end, a couple or three of grand easily.
End result for me is reasonably satisfying.
It does take a little time & sorting out. It is not a bolt up system.

202 to 179 - use the Trimatic?
