APRIL 2019 THE SHOP 39 PRECISION ENGINE that might occur if the hose began to col- lapse internally under vacuum. Initially, this was the pain-in-the-butt part of the job. The stainless steel support coil must be wound counterclockwise to mini- mize its diameter (bringing the coils together, forming a tube), and then push-fed into the hose, pretty much one to three coils at a time. I lubed the inside of the hose with engine oil to ease insertion, but this was time- consuming and frustrating in the beginning until I developed the knack. I installed one hose end, installed the support coil, then installed the second hose end. The internal support coil comes in a 4-foot length. I cut two pieces with a snip, one for each hose. I tailored the coil length to match the full hose length between the hose ends (with the ends of the coil about 1/2- to 3/4-inches shy of each hose end). By the time I finished installing the sup- port coils in the two vacuum hoses, I had resurrected just about every cuss word in my vocabulary. Of course, after fitting these two hoses, I felt like a pro. See image 2. ALTERNATOR SETUP I mounted the Jones Racing alternator on the left side, using the existing threaded holes on the block face. The Jones mounting bracket fit like a glove, and it's pretty to boot. Belt adjustment is a breeze, thanks to a heim joint-ended LH/RH thread hex bodies turnbuckle. This is without a doubt the best-fitting and easiest-to-install custom alternator setup I've ever had the pleasure of installing. Jones offers a multitude of alternator bracket configurations (for high-mount, low-mount, LH, RH, etc.), but I really like this little bugger. This is a nice application for both race engines and street rod builds, offering both form and function that would please even the most finicky customer. CARBURETOR/FUEL PLUMBING Our big-gulp carb is Holley's Ultra Domi- nator P/N 0-80673, a 1,150-cfm race carb that features billet metering blocks, three-circuit metering, mechanical secondaries and over- sized sight windows for easy float adjustment. Recommended fuel pressure is 5-7.5 psi. The anodized billet metering blocks feature changeable idle feed restrictors for easier tuning of the idle system with no drilling, in addition to changeable emulsion jets for infinite metering tuning.
