I have completely installed the new 455 in my 71 98 (can't wait to start it). I have W/Z manifolds on it. I've read in multiple locations where Joe P mentions that headers require relocating the brake distribution block. Does this also apply to W/Z manifolds? The manifolds are in the car without pipes but it is awful close between the starter and the brake distribution block on the driver's side. I think the pipe will clear but I am worried that I might have heat soak problems. Can this cause the brake fluid to overheat, or am I just being paranoid?

 

I can't see where it would. W/Z are what the factory put on 1971-74 455 DE big cars.

 

Thanks, I guess I was just being paranoid.

 

Here's food for thought, 66' Olds A body with the 400 with DE used different brake line routing for the left side. Six cylinder and 330 Olds A body are not the same.

No, it applies to headers.

 

Thanks again. I just wanted to make sure.

 

I thought they had heat shields for the starters ? My 72 starts hard when it is hot but it always starts. Who sells the heat shields ?

 

I've heard the same thing. Mine didn't have a heat shield when I disassembled the engine. Maybe because it is a C body...

 

http://cgi.ebay.com/ebaymotors/OLDS-...=p4506.c0.m245 just bought this on the bay says he has 3 more.

 

I have been running a stock starter on my 455 in my 57 (10.5.1 compression) since I installed the engine. Never starts hard even after driving in our recent 99 degree plus weather. I believe most hard starting problems are related to timing and not to heat when using cast iron exhaust manifolds. Can't comment on headers, haven't used them

 

The eighties rear drive Olds had a factory heat shield...it replaces the diagonal brace from lower front end of starter to upper end on the block...it is almost rectangular in shape...I haven't the part number handy...but it is pretty cheap
