It has made me wonder if anyone has done that to a 216.
How much did those parts effect HP, MPG, acceleration, top speed?
And last how did running dual exhausts sound?

Not much in the 216 for hp gains with those add ons.

The dual exhaust scavenging makes the carb(s) run lean and the loss of exhaust heat under the intake makes the engine cold-natured and almost impossible to tune.

I also used water heat. But it runs just fine. | | | | | Joined: Jan 2015 Posts: 914 'Bolter | | 'Bolter Joined: Jan 2015 Posts: 914 | I don't know, I am using the set up from Langdons, and it runs quite well, I do have higher compression, and an RV style cam.

Though it is my son's truck and he has no desire to put any "speed" parts on the truck. Though I did hear some 216's on YouTube with dual exhaust and they sounded nice though it was not given/clear what other engine mods were done. | | |
