What is the base engine used to build the 540 Ford?

A production two-bolt 429-460 Ford block and a 460 crankshaft from 1968 or later, using Ford 240-c.i. six-cylinder truck rods that are 6.795 long.

How much power does the 540 Ford build make and what does it cost compared to alternatives?

It's a simple 700-hp engine that can be built at approximately 50% of the cost of a $20,000 Chevy Bowtie 540 or a Ford 540 SVO engine, and it's extremely reliable.

What bore size and cylinder-wall thickness are required?

Bore and hone the engine to 4.500 (.140 over stock). After sonic-checking, subtract .070 from each side for net wall thickness; a minimum of .125 on thrust sides and .080 between cylinders is fine.

How is the stroke increased on the 460 crank?

The 460 crank's 2.500 rod journals are offset ground to 2.1222, increasing the stroke from 3.850 to 4.225.

What deck height should the block be cut to?

Cut the deck to 10.310 to 10.315 and square them, then hone the cylinders to 300 to 400 grit.

This is page one of a Hot Boat magazine article, 'Return of the 540 Ford,' by Drew Backlund, a reprint of a feature that originally ran in the August 1995 issue. The article explains how to build a reliable 700-hp 540-cubic-inch Ford big-block engine for roughly half the cost of a Chevy Bowtie 540 or Ford 540 SVO crate engine. It starts with a production two-bolt 429-460 block and a 1968-or-later 460 crankshaft (Duracast nodular iron), plus Ford 240-c.i. six-cylinder truck rods (6.795 long). Machining instructions include sonic-checking the block, boring and honing to 4.500 (.140 over stock) with minimum wall thickness of.125 on thrust sides and.080 between cylinders, cutting and squaring the deck to 10.310-10.315, deburring oil drain-back holes, and honing to 300-400 grit. Crank work covers Magna-fluxing, offset-grinding the rod journals from 2.500 to 2.1222 to increase stroke from 3.850 to 4.225, chamfering rod oil holes, and grinding V-slots on the main journals for pressure-feeding the rod bearings. A photo shows the author with two 700-hp offshore engines flanking a 351 Ford NASCAR engine. The article continues on a subsequent page.
