Chevrolet big-block engineThe Chevrolet cubic-inch, V8 engine debuted in limited numbers inbut it wasn't mass-produced until Chevrolet used performance s in Corvettes and Camaros, and it used lower horsepower versions in family station wagons. Chevy's first generated horsepower, but it often was tuned to produce horsepower. Chevrolet sold it in as an option. The went on hiatus until Chevy developed two other versions in One was the low-compression The other featured a four-barrel carburetor and a compression ratio that produced horsepower and pound-feet of torque. All s featured a 4. ByChevrolet offered horsepower ratings of and on two s, with the torque rating for both at pound-feet. The horsepower remained untouched. However, Chevrolet introduced its L71 with three two-barrel carburetors to generate horsepower and pound-feet of torque. Yenko boosted the horsepower from to with the same torque rating at pound-feet. A Chevy equipped with a Yenko could go from 0 to 60 mph in 4.

I am on a limited budget but i think with good deals on everything i can get what i want over the horsepower small block i was running. What heads will support horsepower? I want enough flow to support some good horsepower. What size cam would you run with this setup. Id prefer more of a nitrous grind cam as I plan on running a shot of nitrous on it. Re: What heads,cam,intake to build horsepower Big Block Chevy?? This engine has run a best of That calculates out to just shy of HP at the flywheel. These heads are very mildly built with 2. If you choose to not use factory castings, then go with the Merlin oval ports. I plan to do some testing with an Edelbrock RPM dual plane this summer. I'm running a small Comp Cams street roller grind XRR and I'm sure someone can point out a good castingThe open chambers provide better flame travel than the closed. According to John Lingerfelder oval port heads are superior under rpms. Look out for the peanut ports that came on trucks. Edelbrock Performer RPM or air gap should fit the bill for your rpm range. Slowazz is right about the heads. They said they are ported and they are bare. Is that a deal????

Welcome to Club Hot Rod! I want to register an account for free right now! Forum Rules. I've got the pass side body mount almost done, trying to post pics. I'm looking into getting a plasma cutter. They are cheaper than I expected. I'm looking close at one with good reviews, Thanks guys! Today I was block sanding some core support parts for one more spray. Making black powder out of black epoxy primer. Not all that exciting, so I didn't take any pictures. Welcome to CHR! Did you buy this entire kit from American Billett? Do you literally just hold a torch near or under the wet paint? Remember Me?

I'm running a th tranny in a El Camino. I tuned it somewhat on the street before I went It made over HP from rpm to rpm. I believe I let off at rpm because it dropped like a rock after that. It made Torque from rpm to rpm.
Chevrolet 427 V8 Engine
The Chevrolet "Big Block" is a term for a series of large displacement V8 engines that have been developed and produced in the United States from the s until As American automobiles grew in size and weight following the Second World Warthe engines powering them had to keep pace. Chevrolet had introduced its popular small block V8 inbut needed something larger to power its medium duty trucks and the heavier cars that were on the drawing board. The first version of the "Big Block" V8 Chevrolet engine, known as the W-series, was introduced in Chevrolet designed this engine for use in passenger cars and light trucks. This engine had an overhead valve design with offset valves and uniquely scalloped rocker coversgiving it a distinctive appearance. The W-series was produced from toand had three displacement options:. The W-series engine was made of cast iron. The engine block had 4. Heads used on the high performance and engines had larger ports and valves than those used on the and the base passenger car and truck engines, but externally were identical to the standard units. No satisfactory explanation was ever offered for why this change was made. However, it did provide a fairly reliable way to differentiate between the smaller and larger versions of the engine. The push rods also acted as conduits for oil flow to the valve gear. Due to the relatively low mass of the valve train, mechanical lifter versions of the W-series engine were capable of operating at speeds well beyond RPM. The combustion chamber of the W-series engine was in the upper part of the cylindernot the head, the head having only tiny recesses for the valves. This arrangement was achieved by combining a cylinder head deck that was not perpendicular to the bore with a crowned pistonwhich was a novel concept in American production engines of the day. As the piston approached top dead centerthe angle of the crown combined with that of the head deck to form a wedge-shaped combustion chamber with a pronounced quench area. The spark plugs were inserted vertically into the quench area, which helped to produce a rapidly moving flame front for more complete combustion. The theory behind this sort of arrangement is that maximum brake mean effective pressure BMEP is developed at relatively low engine speeds, resulting in an engine with a broad torque curve. With its relatively flat torque characteristics, the "W" engine was well-suited to propelling both the trucks and heavier cars that were in vogue in the USA at the time. The W-series was a physically massive engine when compared to the "Small Block" Chevrolet engine. The first iteration of the W-series engine was the "Turbo-Thrust" cubic-inch 5. It was produced through for use in large Chevrolet trucks.
