Hi again, and thanks for your notes !
Well, it is not a real -67, a 351 block will be just to take a very big risk. and this thing is meant to be driven. So, it is dressed up to be a -67, but block is a 454 marine block, bored .100over. still 3,75 stroke, so total of 447. heads are Merlin cast iron. so the whole engine is very heavy. And further plans would be to put in a complete AL-engine (like ZL-1), but first I have to get the thing working. I have prepped the whole car with a lot of sensors and measurement equipment, so at chassi dyno test, we will learn more about how everything will read. Air/fuel ratio is measured. And we have sensors and already measured backpressure on free reving, almost no response on pressure. Really difficult to measure, but we have good experience and a working position and sensor. Dyno will show. The sidepipes are built with a lot of experience. A friend have same installed on -66 with SB, and it passed annual safety inspection. But this is more loud with BB and close to 12:1 in comp. Inspection here is somewhat of a subjective evaluation. So it is just to go in and test. If don't pass, we have prepared to put in restrictions in the pipe, just for safety inspection. We have made a reference measurement with a static sound pressure, for reference. I will report how it will go. If all goes well now, I plan on making the safety test during April.
rear end is 3,70, and matched to engine at max. 6000rpm will give max. speed at 180-190.... I have several other rear ends with other ratios, depending on what will be driven....
More pictures will follow as I proceed
best regards !
