1970MonteCarloNH Posted June 17, 2017 Share Posted June 17, 2017 Hey guys what are some of the headers you are running on your Monte with big block and how is the fit ? Thinking of hooker or dougs but heard hooker is terrible fit Quote Link to comment Share on other sites More sharing options...
72-CLASSIC_RIDE Posted June 17, 2017 Share Posted June 17, 2017 I opted for Doug's when I upgraded and bolted right up. They fit great & believe the P/N was 333-C (Ceramic Coated). Beware when stated Chevelle, Monte Carlo in part description as there is a difference between the two fitments. Been on for at least 8 years and no issues.

1970MonteCarloNH Posted June 17, 2017 Author Share Posted June 17, 2017 So just curious what would be better to go with 1-3/4" or 2-1/8" ? Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted June 17, 2017 Share Posted June 17, 2017 So just curious what would be better to go with 1-3/4" or 2-1/8" ? 1 3/4"!!!!!!! I have 2" on my stout 10:1 454 and wish I would have went smaller, esp on a street driven engine Quote Link to comment Share on other sites More sharing options...

Sam (Bones) Posted June 17, 2017 Share Posted June 17, 2017 more bottom end torque, street engines spend most of their time from 1000-3000 rpms, yes they take short blasts to 5000-6000, but really....how often? for a spunky, fun street car...1000-4000 is where you want your best power, and when I say power...I mean torque, I could give a crap about horsepower, torque is what you want bigger tubes are only going to help in the way upper rpm's and 2 1/8" tubes are way too big for anything under 500 cubes unless it's built for extremely high rpm's I have 2" Hookers, wish I would have went with 1 7/8" tubes, I also have a 3 1/2" exhaust which I'm thinking about removing in favor of a 3" or less more is not always better esp with a internal combustion engine my burnout video below....that's a 12:1 (yes 12:1) 468 ci spinning at 7000 rpm with 2" tubes thru a 3 1/2" exhaust Quote Link to comment Share on other sites More sharing options...

Doug Oh no worries at all brother - btw are you happy with your headers ? Did you have to beat them up to get them to fit ? Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted June 18, 2017 Share Posted June 18, 2017 The smaller primary tube headers are fine for a stock or mildly modified 454. Once you get crazy or hit like 500 inches, you'll be better off with 2"+ primary tube headers. And because it hasn't yet been stated, shorty headers are only slightly better performing than stock iron exhaust manifolds. Quote Link to comment Share on other sites More sharing options...
