Will I need a new PB unit ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I put my Big Block in will my Power Brake Booster be in the way? It looks like it might hit the Valve cover.

HI STEVE IT'S SELDON I PICKED UP THAT TRUCK FROM YOU A WHILE BACK. I HAVE A BIG BLOCK TRUCK AND A SMALL BLOCK TRUCK AND THE BOOSTERS ARE DIFFERENT IN DIAMETER AND DEPTH. HOPE EVERYTHING IS GOING WELL.

I'm willing to bet that you won't have any problems. I have a booster from a 3/4 ton with a 350, and I have that big 'ole caddy engine in there, it sits way higher than anything GM installed, and I still have plenty of room.

Hey Seldon. Things are going well, thanks for the info.
Longhorn, My booster looks diff. I'm not REAL sure if its orig. I'll have to get a pic.
Big O. I should rephrase. It looks like it may hit my TALL valve covers. How close do they set originally?
