Brand new in the box-not sure on engine/options combo. Fits all GM A body 68-72- Believe thay are big block replacements Catalog prices them out for $100--- I'll go $75.00 OBO THANKS!
according to Summit Racing application, these are correct for 72 GS 455. They list a different #5536 for 70-71 GS 455. Not sure why? I would think the 72 would be beefier to compensate for the weight of the smog pump and controls.
Well....my car is a 69 Skylark equiped with a/c. I would prefer a slightly higher ride height since I will be running full length headers, but then again I dont the car to look like it is under hard acceleration while it is parked...ya know? THe wheel wells up front are right at 26-1/4inches with the old springs. I will be going from the 350 to a 455 with iron heads(aluminum intake-headers). Regards, 455NGLIDE
