Re: Chevy 366 hop up
Its real simple I had a 76 Blazer had about 80k miles of documented use and MPG records buddy called and said he had a FREE set of aluminum coated headers for me a guy had bought them for his Blazer and never installed them at the time I needed a new exhaust so since the price was right took the FREE headers, installed they didnt fit for **** hit the starter had to remove the starter heat up all the tubes with a torch then put a 4x4 between the block and header bend it out to clear the header, install heat shields to prevent it from cooking the starter, then took it to custom muffler shop to have duals in stalled, the next 80k miles the MPG didnt change, no gains, just more noise and problems trying to keep spark plug wires from burning up dumbest thing I ever did was remove the factory single exhaust and manifolds and install FREE headers!
I have seen dozens of other owners with the same thing.
Psychologically their is a LOT OF GAINS problem is they are NEVER backed up by anything scientific unless your the MFG supplying the dyno results for the magazine your now advertising in thats writing a favorable review for you since your now paying him for the favorable review.
Do headers work YES in specific applications they can help go they work on every application NO they dont.
Save all your BS unless you want to come back with some technical documents like some SAE documents then I would be willing to listen and or read those documents, telling me all your lame BS engine building 150 years of drag racing crapola bla bla bla you can save I have heard it all before not one of you have ever drag races with factory manifolds so have no data to back up your seat of the pants psychological gains you brag about.
Would I see more power if I was going to install headers on my engine then run it 2000 RPM more than I normally do YES probably but this is not real world gains when I go back to the normal RPMs I gained nothing, so YES your right 'headers create more power' but are meaningless in the real world.
Same goes with motorcycles and ATVs the jedi mind tricks work on them also, cant count the thousands of dollars I have seen people spend on those exhaust that in real life give no measurable gains, those fools actually think the factory engineers left some undiscovered performance gains behind for some guy to discover then sell to you haha.
Anxiously waiting on SAE documents or equivalent to read.... Spare me all the articles written by people who also sell advertisements and call the internal combustion engine a "motor" haha = hacks and quacks call them a motor too stupid to realize the correct terminology ...
