Headers for big block 402..........in a blazer
 

Anyone done this? Already did the fit up of the big block but with stock exhaust manifolds. Trying to decide which way to go. Any help will be appreciated.

I am using Dynomax headers on my 454 in my K20 and they fit with a bit of massaging of the frame on the passenger side, drivers side fit perfectly. The ones I used are Dynomax 67-87 2WD BBC headers, part number 86022.

Here is a link to a bunch of pics of them installed.

I would note I will be using a hydraulic clutch and it does look like the factory clutch linkage would be a problem.

thanks for the info

Any pics of your firewall clearance? Did you move the engine forward or massage the firewall?

Oh, wait, I have some pics of your truck saved that show me what you did. Kind of similar mods that I had to make.
