I have a 1977 F150 short box 4x4 with the 300 I6 and 4 speed manual trans. I was considering adding the Clifford intake, Weber 38 2 brl carb, headers, X pipe and dual exhaust combo. Has anyone added these items to there rig? I would like some feedback as to whether it is a good combo, and if the gains are as great as stated by Clifford Performance.

Thanks!

 

You need to go down to the 6cyl section of the forum, lots of good info there. Maybe a mod can move this for you.

 

I have the Hedman header and dual exhaust on my '79 with a 300 and C6 automatic. There are pictures in my gallery. I'm really happy with how it turned out, but the header was a pain to install. I had to reroute the transmission lines as well as one brake line; I also had to switch to a mini-starter because the standard-size starter can't be removed with the header in place. I also had to shave down the alternator/smog pump bracket (I don't run the smog pump anymore, so I just cut off the top half of the bracket and smoothed it down to fit).

Installing it was a pain as well; I had to remove the passenger-side motor mount and hold the engine up with my cherry picker to place it, and even then it was a challenge to wiggle it in place. Overall a very challenging installation.

I'm running an Offenhauser DP instake and an Edelbrock 1403 carburetor - I'm really happy with those, although the throttle linkage was a challenge as well. In general, the throttle linkage can be hard to set up when doing any kind of upgrade, because of the carburetor's orientation on a straight six. Well worth it though. No idea about the Clifford stuff; as stated the straight six forum would have more info.

 

Thanks for the input. this info helps and I will also brows the 6 cyl section.

cheers
