Here was the last pull on a Dyno Jet. Made 358rw/Tq at 3900 rpm, and 336rwhp at 6100rpm. The tuner said that brand is usually low by 20-30hp/tq when he compared it to a chassis dyno he uses as well. Not bad.
It runs great! No surging idles, don't have to feather the gas at lights, and it hooks straight as can be. And the 5 speed makes highway driving more enjoyable. I wanted a good daily driver tune so I can enjoy it. I wasn't overly concerned with just power or an ET. Timing is only set at 30° as well. All in all I'm happy with my tune.
Here's the 2nd dyno sheet, the last one was corrupt. The HP is lower here BC of the cheap air intake system I had on for mach up. The extra 30hp came from my big 3 ½" custom cold air intake we assembled with a big JLT air filter. Will get those pictures up soon. In the picture you can see the smaller 3" accordion style plastic tubing restricting airflow. But man that thing opened up once we changed it out.
After looking at your picture, I'm concerned about hood clearance with the '96 Explorer motor I just picked up. Does anybody know if the stock upper and lower '96 Explorer intakes will cause hood clearance problems on a '67/'68?
You won't have a problem. I used a 1" phenolic space in between the upper and lower intake and that adds an extra gasket as well. With stock mounts you'll be good. I could have bought expensive motor mounts that lowered my engine enough to accomadate the spacer but the hood scoop was a better choice because I get cool air running into my engine better now.
I think you could go to an intake that came out of an EFI car rather than a truck and you would get better clearance that way. The truck ones are pretty tall......I don't know how much performance you would loose going that route though?
I haven't driven her much since I put it in on account its been 115°F here. So it'll be hard to get a good reading on my IR thermostat. But, I was planning to go through there, was just waiting on my CAI splash shield to get here.
