I have a set of Cosworth forged pistons designed by Jim Evans and sold by Classic Alfa in the UK. I am building a street motor for my 74 Alfa GTV. Can you please tell me the recommended piston/liner clearance for forged pistons used in a street motor built for good power and reliability. A general range is all I need. I would greatly appreciate a reply. Thank you, Mike email@example.com
Thanks for the message. The forum is dedicated to supporting our Electronics products.
If you require assistance with the pistons i would suggest talking to Classic Alfa as they supplied them, or you can call our Powertrain office on 01604 598300.
