The Old Guy Posted February 15, 2006 Share Posted February 15, 2006 They will all fit as long as you block the heat . The early 455 (70) intake will work, but the later intakes will need the heat to the carb blocked as they changed the port configuration. Link to comment Share on other sites More sharing options...

Guest wildcat65401 Posted February 17, 2006 Share Posted February 17, 2006 Now the guy I'm getting the parts from told me he has the heads also . All of the 455 parts are from a 70' model . Kenne Bell Buick finned valve covers and Edelbrock intake with Buick 455 stamped on it . Can't wait to put it all together in my 68' Skylark and finally get the chevy 350 and trans out of there .

Guest buickapollo455 Posted January 5, 2008 Share Posted January 5, 2008 Factory: the 70-71 have a low intake and heads and wont interchange with 72-6 heads intake, how ever, a full head and intake will interchange just cant mix and match between 70/1 and 72-6. After market intake will cover holes in water jackets for 70-1, follow intake gasket for appropriate years heads. Oiling pre 71 is in journals, 72 on oils thru lifters and push rods. Valvecovers all fit 430/455. use a carb about 800cfm + I used a 875 cfm Holley with fantastic horsepower. Oil galleys in early years suck, must be drilled to 5/8" oil pan to galley and front galley to rear. use late pick up tube on pan to 5/8", use high vol oil pump on all buick or high pressure kennebelle pump using 70 or earlier front cover. Buy the book " guide to buick performance" by Dove at local book seller . Best book for buick motor builder. Link to comment Share on other sites More sharing options...
