This engine was a collaboration between my dad and his cousin. It's a 292, bored .030 over. It's been balanced. It's got JE forged pistons that puts the compression at about 10.5:1. It has an Engle cam with 231 @ .050 duration and .565 lift. The head is a lump port head by Glen and Kevin Self with Ferrea 1.94/1.6 valves, K-Motion springs, Bill Smith pushrods, and Harland Sharp 1.75 roller rockers. The oil pan is a polished Hamburger aluminum pan, and the timing cover is a Frank pattern finned aluminum unit, and it has a custom made ATI Super Dampner and aluminum Fidenza flywheel. The intake manifold is a Clifford 4 barrel, with a 2" Super Sucker spacer and currently there is a Holley 750 carb on it that will probably get replaced with a Predator. This is going in a Diamond T pickup with a Richmond 5 speed behind it. It's estimated to make around 450hp and 500ft lbs.
Thats kickass. What is the point of those pushrod covers anyway? Other than leak oil, are they used to set the lash or anything? I had a 250 I6 in my first car and one of the covers always leaked.
Guy that goes to the Arlington albertsons meet has a pretty nice sounding inline in his 60's something Mustang that sounds pretty nice. Was suprised by they way it sounded.
One of my friends is building a 34 GMC truck rat rod with a pontiac flat head straight six. One of 4 made that year. He has spent a pretty penny to get it running. But it's only making 250 hp.
My current I6 makes as much power as my old V8 SN95 stang woulda made after a PI H/C/I swap. I am actually still considering the TT 335i over the 8 cylinder /m3.
Does anyone make a composite intake for I6's? With the intake sitting right above the headers I bet it would pick up some nice HP from not soaking up heat.
Summit or Jegs used to carry a phenolic spacer for the ford "small-sixes" that looked like it would help. Honestly, though, Aussie crossflow heads are the way to go. They eliminate a lot of headaches, and flow like a sumbitch. They're also not as unobtainable as people think they are.
Also, I think CJ posted a thread a while back about building two extra cylinders onto an SBC head for a 292 build, thus satisfying a need for crossflow. It was pretty badass, IIRC.
I have a buddy with an old dodge dart with the I6. I think it is time to get it running.
