Roller lifters on 403
Hello Everyone !
I'm new here, french guy discovering the forum and looking for some help. https://classicoldsmobile.com/forums...lies/smile.gif Maybe somebody could help about a big problem i'm dealing with... I'm modifying the 403 Olds of my '79 Transam. I've replaced the camshaft by a roller one from comp cams. Roller lifters are from comp cams too. Problem is lifters hit the 2711 Edelbrock intake manifold on cylinders 4, 6 and 3. I resolved cylinder 6 and 3 lifter clearance problem by slightly grinding the intake. But this solution can't be used for cylinder 4 lifters because too much material have to be removed. I've trier to flip the lifters, so the link plate is facing toward the block. It works for the clearance but in this configuration, the pushrod hit the rivet of the link plate of the lifter. Even if I use 5/16 or 3/8 pushrod. I must keep the 2711 intake because of the shaker hood clearance. I must admit that I lack of idea. Is anyone knows this problem ? Is there a solution, like anoter lifters I don't found ? Thanks for your help. https://classicoldsmobile.com/forums...lies/smile.gif Regards |
