Sorry for re-asking this, but as I begin fiddling with mechanical and electrical components for my project 6 conversion, I am still pondering this decision.
The car, when finished, will be shipped to Europe where my wife and I can use it when we're there, and do some rallies, trips and such. There will likely be (months-long) periods of no use. Have most of the necessary stuff for the build, (included with the '71E motor-entire MFI, fuel filter/console, complete electrical board, fuel pump, etc) all from 'donor' car... But I'm beginning to sense that the complexity of MFI (transducers, fuel system, micro-switches, etc.) could prove challenging. A good set of PMO's on the other hand: basic fuel pump and regulator, MSD 6AL, and a spray can of ether may be better suited, again given the intended use. So, I welcome thoughts and opinions-thanks |

For the Jenvey carbs, is that price per, or for a pair? Ouch, that is pricey and I may have to upgrade my original estimate on price, a lot. Add a controller and all the other bits and bobs you need, it becomes very expensive. I do understand the allure of EFI though, especially after a face full of petrol.

The Jenvy throttle bodies are designed to look like carbs. Most throttle bodies are way cheaper, but they don't look like carbs. PMO throttle bodies are blatantly throttle bodies and do nothing to hide it. They are probably better throttle bodies than the Jenvey ones. What you are paying for with the Jenvey ones is the stealth factor. |

What you are paying for with the Jenvey ones is the stealth factor. We sell both the PMO and the Jenvey. Both are of the same quality. Jenvey is top notch. Also the Jenvey will fit common IDF/IDA air cleaners, run standard IDF/IDA linkage, fit IDF/IDA manifolds, has PICO fuel injectors included, had TPS (throttle position sensor) included, has fuel rails included. We went down this road with Borla as an example... once you got all of the other parts, the price shot up there and, custom air filter bases had to be fabricated. Price adjusted yesterday to meet current exchange rate. (IMG:style_emoticons/default/wink.gif) ALSOOOO... here's a lower cost set if you already have the manifolds and linkage: https://pmbperformance.com/products/jenvey-...-ida3-42mm-pair |

Already have crank-fire ignition, so this is pretty interesting. |
