One perhaps aimed mainly at our growing number of readers based in North America although Summit Racing ships worldwide.
If you’re planning to lean hard on the nitrous, boost, or RPMs with your next small block Ford build, then a Summit Racing™ SPC Engine Block is the foundation you need.
The SPC Ford blocks are built like Tiger tanks. They are cast from German class 35 gray iron and have extra thick material where it counts the most. This gives them loads more strength than factory Ford castings, allowing them to safely handle up to 1000bhp.
For 302-style builds, choose one of the 8.2in deck height models in your choice of 4.0- or 4.125in cylinder bores. If you’re a 351Windsor-fan, you’ll want the 9.5in deck height version with a 4.125in bore.
Other features include:
• Cast in a Tier 1 OEM foundry in brand new moulds
• Machine-finished in the USA
• Priority main oiling
• Heavy-duty main webs
• Siamese cylinder bores
• Nodular iron main caps
• Four-bolt splayed center main caps and two-bolt front and rear caps
• 4.165in maximum bore diameter
• Blind head bolt holes
• One-piece rear main seal
• Notched for stroker crankshaft clearance (8.2in deck height blocks only)
• 8.2in deck height blocks use 7/16in head bolts; 9.5in deck height blocks use 1/2in head bolts
The Summit Racing™ SPC Small Block Ford Engine Blocks ship with cylinder bores that are .005in undersize so you can final-hone them for proper piston-to-cylinder wall clearance. All blocks require SVO-type cam bearings with 2.204in housings (sold separately).
