The 3AC was not nearly as sexy as the old 2TC and 3TC engines in the late '70s Corollas. THOSE were screamers with a set of Weber side drafts.
Talk about fun! My other favorite Jap "box" car, Mazda RX4 with a 13B and a Weber 48 IDA carb. With extend port work, those things were AWESOME! Add a little nitrous and you had a car that would eat a big block for lunch. Heck, who needs Apex Seals anyway? Of course, no list would be complete without the Opel Manta. Fun, fun, fun no matter how you slice it.

Well, the truck's been gone since Monday morning and I have yet to hear back about it......... Yet.
It's something I don't want to work on again. I guess unless it's ball joints or something not related to the transmission or engine.

Finally finished up my customer's Mustang project too. I guess the dyno/tuning at the end of the project has made up for all the grief. We didn't put the smaller pulley on for reliability reasons till it is safely back in Florida. At 8 psi it is laying down 455 hp at the wheels. Test drives working out some part throttle issues have been fun.

Three months it's been gone and I haven't heard back from the guy so I guess he either hasn't driven it at all since he picked it up or he sold it.

Or it's been working perfect, though its nice to hear that from a customer since usually all you hear is when it's not.

Lars,
How difficult is it to clock the crankshaft so you have a true 12 cylinder? One of things I always wondered about.

The owner of the race team came up with an indexable adapter plate that connected the 2 motors. His original concept was to try the 12 cylinder idea. He tried first at a 30* offset from tdc of one motor to the other. This created a harmonic vibration.(To this day I still think it had something to do with the exhaust set up) The best solution he found was tdc to tdc of each motor, so it became a beefy 6. Some of the other trial and error thing discovered were each motor needed its own exhaust system manifolds and piping. Tru duals was to be the optimum for each motor but due to clearance issues 2 into 1 systems were utilized for each. So it looked like dual exhaust but was actually a seperate outlet pipe for each motor. He even prototyped a intake manifold for a holly 800 that connected both motors but the outer most runners were lean an the inners were rich. If he could have put an EFI system on this application it would have been the cats meow for the car.
He was the type of guy that would tear everything down and start in a new direction any time he encountered a problem. Wouldn't keep any of the old concepts they would just become scrap.

I know from experience, some people can be the pickiest, finding fault with imaginary problems, and others could have a serious complication and be the most understanding and patient person you could think ever existed. Hopefully everything is just working fine, and the guy understands that rebuilds are not always just like a brand new factory engine and appreciates/understands that fact.
