I am putting a bigblock in my 71 c10 and I'm wondering if I will have clearance issues between my tall valve covers and my stock brake booster. If I do have issues can I run a smaller one and will a smaller one cause braking issues or is the newer brake booster better than the stock one? Lastly if I do have to go smaller is there a brand I need to buy or vice versa stay away from?..Thanks

I'm not sure if you're going to have an issue there. I never had a big block in a truck like that but I don't see why it would hit? The place I would be looking at would be the recesses firewall. I had a 72 K5 Blazer and the tall valve covers on a small block hit the firewall where it recesses in.
