What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the benefit of using narrowed conrod bearings in my Chevrolet Small Block?
Narrowed conrod bearings, like the ACL RACE Series, provide additional edge clearance for crankshafts with large fillet radii. This is particularly beneficial in high-performance applications where optimal fit and reduced friction are critical for engine efficiency and reliability.
Which Chevrolet Small Block models are compatible with the 8B745HN conrod bearings?
The 8B745HN conrod bearings are specifically designed for Chevrolet Generation I Small Block V8 engines, compatible with models including the 265ci (1955-1957), 283ci (1957-1967), 302ci (1967-1969), and 327ci (1962-1969).
What is the maximum shell width of the 8B745HN conrod bearings?
The maximum shell width of the 8B745HN conrod bearings is precisely reduced to 20.12mm (0.792 inches), ensuring an optimal fit for applications requiring extra fillet clearance.
When should I choose the narrowed conrod bearings over the full-width set?
You should choose the narrowed conrod bearings (8B745HN) when your application requires extra fillet clearance due to large fillet radii on the crankshaft. If extra clearance is not necessary, consider using the full-width set (8B745H) instead.
Are these conrod bearings suitable for high-performance applications?
Yes, the ACL RACE Series narrowed conrod bearings are designed for high-performance applications, providing durability and reliability under increased loads and stress typically found in racing or modified engines.
