My Odometer broke so I have no mechanical record of my engine's miles since my rebuild, this is my third Speedometer and this was NOS, these all had odometer problems, could it be too much speed ? Will fix it later Back to the heads, compression still good at 118 PSI exactly all around, according to my 2 temp sensors, they do seem a little cooler than the stock heads, the 3/4 inch plug reach seem to have heldup and not cracked under daily 90 mph and max of 410 degrees uphill lugging on cylinders 3 and 4 . Heads are cool at a long border wait of 2 hours (at 260 degrees) while I see the water cooled cars overheat and spill water all over the place, even new cars. Heads are cool enough that the typical golden color under the valve covers is not present, still looks new. I have 042's with 3/4 long reach plugs. I am so far satisfied with the heads until cracking melting will eventually take place, knock on wood . My engine: My engine runs very good but ever since I switched to hydraulic tappets and a 'stock' hydraulic cam, my car does not jump to quick signal lite take offs like it used too. I think the cam is not really all that stock and has a little upper midrange power, low end is ok. My engine has an automatic tranny that requires low end power to take off good. I hit 90 mph easily though. My ignition, I think is acting up above 75 mph , I can barely feel a miss and loss of power eventhough reaching 90 is not a problem. My wires are covered with a coating of black soot like as if a high voltage corona is present, maybe this is caused by too much voltage from my hot coil/open electrode combination, there are little blemish spots on my wires , I think I need new wires dist cap and rotor, it is possible the the resistor in my rotor burned up under too much current. This is just a slight problem to be corrected this weekend. My Gen light turned on yesterday and it took me 10 minutes to change the brushes that I stored in my glovebox. Easier that fixing or replacing an alternator for sure , thank God. My Bugpack muffler/extractor that I bought a year ago just fell apart from several places, I decided not to frankenweld it again. I put in the muffler/extractor from a free engine I got in LA . This was made by Thunderbird very, very nice quality, big heavy tubes with a full size header gasket, it looks kickass and it even fit behind the skirt, one problem though, It fit my free engine but it did not fit my car's engine , now I know ALL OF OUR ENGINES ARE OF A DIFFERENT WIDTH DEPENDING ON DISPLACEMENT OR WEAR. I had to go to my local Tijuana mufller shop that heated and custom bend the setup right on my car for 15 bucks (they thought they gouged me). While there for the same price, I had them weld one of those glasspack mufller tips , looks nice. This setup had so much corrosion from being outside for years in someone's backyard that rust and scales poured out . The black paint is now burning off. I hope it lasts, my next new setup may be from Kymco or Thunderbird . The sound: very quiet compared to anything I ever had, it just purrs no more roaring, I like that, I can now speak using normal volume inside the car, got to attack the high pitch wizzz around my front quarter windows. Sorry for rambling have lots to ramble about but do not wish to bore anyone . LEON MARTINEZ 1969 SQUAREBACK EFI/AUTO 1967 FASTBACK PROJECT SAN DIEGO AND TIJUANA </x-charset>
