Meagre cars on the street Order as all the more carefulness as a machine with a 6-71 supercharger sticking up down the hood. From the mind-boggling effectiveness and response to the marvelous looks and sounds, it's reward every cent. Not single does it flash deluxe, on the other hand it increases Gauze milage, as expanded as you are driving enjoy a typical human life (as opposed to a rapidity demon). It is shocking to study 18 miles per gallon on a 350 cubic inch supercharged engine.
Instructions
1. Ensue all of the steps for building a supercharged engine, and it Testament extreme as extended as a customary engine. Everything practicable breaks on supercharged engines, so determine and comprehend what it takes to direct it stable -- gain from someone with 40 age of drag racing familiarity and learning the callous custom.
2. Acquire all the parts. Dispatch the block to the mechanism shop--in Appendix to the prevalent occupation done on a morals block, you will need To possess the block magnafluxed and checked for path Muzzle. The mechanism shop Testament further situate the rods on the pistons and immensity the rods to the Eccentric person for you. Own the apparatus shop contain a dual keyway in the steel Eccentric person and the harmonic balancer.
3. Put the engine together. When you get to the bearings, make sure there is no more than .003 clearance on the main bearings. Use the Childs and Albert piston rings for the top ring, and the Speedpro rings for the other two.
Add the short snout water pump and the fluidamper harmonic balancer. The typical long snout Chevy water pump will hit the blower belt, so this must be changed out. The fluidamper harmonic balancer needs to be a one-piece harmonic balancer.
5. Make sure the camshaft is cut for a blower, as it works more on the exhaust side. This is very important, as it will need to match with the rest of the block and the heads. The lift of the camshaft will also figure in the overall power of the engine.
6. Put the high flow heads on the block. If you plan on racing this engine, you should use the copper headgaskets. If you are simply going to be fooling around on the street, the Felpro gaskets are fine. Be sure to use the ARP bolts when putting the heads on. The high flow heads should have larger exhaust valves, strong springs, stainless valves and bronze seats. Again, this is important--what goes in must come out.
7.4. Check the total compression of the engine combination you chose. It should not be more than 8.5:1 total compression on a blower motor. Once under load, the compression will increase dramatically with the blower. The typical rubber harmonic balancers will disintegrate.
8. Finish off the engine up to the intake manifold. Add the blower. Use the 6-71, as the 8-71 is for fuel injection (which is very expensive and generally only used in racing applications). Do not tighten the supercharger bolts more than 12 to 14 foot pounds, as they are aluminum, and designed to break away.
9. Top the blower with two 450cfm carburetors (or two 850s if you are going to be racing). You will need to have a high volume fuel pump and a fuel pressure regulator. You do not need additional pressure to have enough fuel for the blower -- just volume.
10. Use a low-profile distributor (nothing else will fit). A trick is to use a points distributor with an MSD-BTM box. The distributor points only act as a switch for the MSD and do not burn out.
11. Install the exhaust evacuation system with one-way valves on the headers so they can rid the crankcase of blowby; this helps power and economy while protecting the engine. They should not be angled more than 15 degrees, or else you will have too much vacuum, and that will suck the oil out of the valve cover.
