A SBC 305 bored 40 over refers to a small block Chevy 305 cubic inch engine that has been bored out by 0.040 inches, increasing its displacement. This modification typically brings the engine's total displacement to approximately 316 cubic inches. Such modifications can enhance performance by allowing for greater air and fuel flow, resulting in improved horsepower and torque. This engine configuration is commonly referred to as a "306" or "SBC 306."
The rotation is clockwise. Answer. If unsure, look at your fan blades, to see which way they rotate!
A small block Chevrolet (SBC) 400 engine has a stock bore of 4.125 inches and a stroke of 3.750 inches. If you bore the engine "40 over," it increases the bore by 0.040 inches, resulting in a new bore of 4.165 inches. To calculate the cubic inches, use the formula: ( \text{Cubic Inches} = \text{Bore}^2 \times \text{Stroke} \times \pi / 4 \times \text{Number of Cylinders} ). This results in approximately 406 cubic inches.

The numbers 4615--6 and 4714T suggest that the roller camshaft is manufactured by COMP Cams, a well-known company specializing in high-performance camshafts and engine components. These numbers typically indicate specific part models or series within their product lineup. For precise identification, it's best to consult COMP Cams' catalog or website for detailed specifications related to these part numbers.
PRISM could be some nifty acronym for something but i believe it is a simple one word explanation and inside joke for the general method the NSA is using to acquire data. According to the website thefreedictionary.com the definition of a prism as it relates to optics is: a transparent solid body, often having triangular bases, used for dispersing light into a spectrum or for reflecting rays of light. At some point outside of the actual physical location of a given company's data center they are intercepting the fiber optic backbone/cable that is carrying data to and from the internet to the data center. A fiber optic cable splitter is placed on the cable and all of the packets that pass through the device are sent to both their original destination and to the NSA's collection facility or data center. This could account for the vehement denials by the named companies that they are providing unfettered access to their servers. The NSA would not need internal server access if they were getting the raw feed. The infamous Room 641 in the AT&T facility in the SBC Communications Building in San Francisco, California, USA was used for a similar purpose: "...It is fed by fiber optic lines from beam splitters installed in fiber optic trunks carrying internet backbone traffic," as described on wikipedia.org in the article on Room 641.
A 305 has a 3.736" bore and a 3.48" stroke. The formula for volume of a cylinder is pi times the radius squared times the stroke times the number of cylinders. So a 3.766 diameter (.030" over) has a radius of 1.883. radius squared is 3.545 times pi is 11.139. times stroke is 38.764. times 8 cylinders is 310.1. So, a 305 bored 30 over is called a 310.
Yes, you can install 305 heads on a 400 small block Chevy (SBC) that has been bored 0.040 over, but there are important considerations. The 305 heads have smaller ports and valves, which may limit performance and airflow compared to larger 400 heads. Additionally, you'll need to ensure proper compatibility with the intake manifold and check for any clearance issues, as the compression ratio may also be affected. It's advisable to consult with a knowledgeable mechanic or engine builder before proceeding.

305 SBC stylesThe 305 small block came with several inductions options over the years, including those witha 4 bbl. Rochester carb as well as TBI (throttle-body injection). if its still in the vehicle - check your VIN# [8th digit] H = Pontiac 305 LG4 G = Chevy 305 L69 H.O.
ya...its a sbc...they all interchange
Before it was SBC, the company was called Ameritech.

firing order is the same for all sbc (first gen)
Probably 300 or so depending on compression and intake. But it would have a rough idle, and wouldn't start making good power until 3500 rpm or higher. Would need the right torque convertor. Probably a loose 10" would work.
None. Almost all SBC use the same timing chain and gears.
