the camshaft and spread the oil pan rails to provide extra clearance
for stroker cranks. The versatile Iron Eagle block is the perfect
starting point for a big inch small block project - you can build
a 455ci small block with Dart!
standard 9.025" and tall deck 9.325" versions allow
for greater versatility.
Raised camshaft .391" (4.912" camshaft to crankshaft
centerlines) provides more clearance for stroker cranks and eliminates
need for fragile small base circle cams. Option for .434 raised
cam also available.
Relocated oil pan rails are spread .400" per side (.800"
wider than stock) to increase crank/rod clearance and reduce windage
Siamesed cylinders: Standard 4.000" or 4.125" cylinder
can be safely bored to 4.185". Extra thick walls prevent
cracking and produce excellent ring seal.
Oil pan bolt holes are relocated in line with main caps to eliminate
interference with rotating assembly.
Main bearing bores are available for 350 (2.45") and 400
(2.65") bearings allow engine builders to maximize crankshaft
strength and minimize friction.

Big block camshaft bearings allow use of cams with larger base
circle diameter to improve strength and recue twisting with cam
Dual starter mounts allow starter to be mounted on either side
