What was the total cost of this budget engine build?

The itemized total was $2,484.00. Subtracting $763.00 of bold-listed optional items gives a 'Maximum Low-Buck Deal' of $1,721.00.

How much did the machine shop work cost?

Listed machine services include bore and hone to 0.030-inch over ($155), install cast-iron valve guides ($100), three-angle valve job ($145), surface heads ($95), install cam bearings ($47), deck block ($55), clean/inspect/mag heads ($35), clean and inspect block and rotating assembly ($85), machine and polish crank to 0.010/0.010 inch ($76), press-fit pins ($60), and resize rods ($85).

What did they use as porting templates for the heads and intake?

They used the intake and exhaust gaskets as porting templates for the cylinder heads and intake manifold, saving time and several hundred dollars by doing the work themselves.

Why should you check that pushrods turn by finger pressure?

With valves fully closed, if pushrods don't turn by finger pressure, the machine shop hasn't measured the pushrods' stock height and subtracted material removed from the heads and deck; that amount should be taken off the top of the valve stems.

Why did they avoid adjustable rocker arms?

Rocker arm studs and adjustable rocker arms would have added $350 to the total cost, so they used the stock rocker arms with Comp Cams pushrods.

This is a scanned magazine page from a "Down & Dirty" column documenting a budget engine rebuild (part of a multi-page "400 build" article series). The page includes two photographs with captions: one showing intake and exhaust gaskets used as porting templates for the cylinder heads and intake manifold, and another showing a combustion chamber cleaned up with a die grinder, abrasive rolls, and carbide burrs to achieve a broader torque curve. The body text discusses final assembly steps — verifying crankshaft spec, degreeing-in the camshaft against manufacturer specs, using stock rocker arms with Comp Cams pushrods, checking pushrod rotation at fully closed valves, and keeping the build super-clean. The centerpiece is a detailed "Cost Review" table itemizing parts and machine shop services with prices, from a Holley carburetor ($280) and MSD ignition and coil ($175) down to press-fit pins and rod resizing. The total build cost is listed as $2,484.00, with $763.00 of bold-marked optional items yielding a "Maximum Low-Buck Deal" of $1,721.00. A footnote explains prices were established by shopping around, using mail-order suppliers, and asking for discounts. Readers can learn realistic itemized costs for a low-budget V8 rebuild and practical assembly tips.
