Way Too Much Back Pressure

[torchred]

Just put a Holley 650 CFM Carb on my truck since the Quadrajet had seen better days and decided to romp on it a little bit to test it out. One of the previous owners mixed 2.5 in and 3 in tubing on it and made stainless steel glasspacks. It blew the welds and the bolts out of the header. Planned on doing my exhaust this weekend anyways (changing headers, pipe, and mufflers) she'll be fixed soon.

The home made mufflers back it up?

that APPEARS to be the older holley. yes, I have exploded my ehaust in my youth with holleys. after you fix the exhaust, check your power valve, little diaphragm thing screwed into the meterig block, behind front uel bowl, make sure you didnt blow that too

After I messed up the exhaust, I put the Holley on it and then redid the exhaust, did the headers pipe and mufflers. It's doing fine with the Holley now. Sadly I found out my firewall is rotten not just rusty, so she needs a new body.

A type of carb has nothing to do with busted exhaust...
