Ebay

I have heard its a Ford pattern too. Still a dumb pattern to use given they use the same pattern on the LS intakes they make and try to market. Knowing some guys are going to put them on LS applications using the stock throttle body. Its a dumb over sight on their part and costs them sales.

 

Yeah I agree its dumb. I have a ls to ford adapter on my wilson elbow lol

i cant seem to find that intake. Do you know who was the seller?

 

I bought the last one the Ebay seller had.

Just saw these popped up even cheaper on Amazon.

 

I am going to have to build a compressor relocation bracket setup.

 

Just felt like updating this post. Since the heads came off and I replaced the JEGS head bolt set that had 4 broken bolts with ARP studs, I have been driving the thing as a daily. It has a set of noisy LS7 lifters in it and I have been running 1.6 rockers on the intake and 1.5 rockers on the exhaust. The Rhoads V-Max lifters pushed the IVC a bit early for the compression ratio and small 218/228 cam on a 108 LSA. Currently running the L31 marine cross ram manifold that I did some port work to.

I have a custom grind cam for it and a set of Lunati lifters that I believe are made by Morel. The cam is an Erson that Lloyd Elliot and I speced together. It is like 272 @ 0.006, 219/219 @ 0.050 on a 112 LSA and 0.544 lift with 1.6s. I am going to advance it to a 108 ICL when it goes in. I am planning to put an Indmar L31 marine manifold on it when I have it apart. The Indmar manifold is kind of like a tunnel ram, has a massive plenum and will have a Fitech 92mm 4 bolt LS throttle body on it.

I have been too busy with other things to pull it apart and it is difficult to pull apart an engine that runs as well as this one does even if the lifters are a bit loud. I ran the van across a CAT scale and it is 6,940 lbs with a full tank of fuel and me in the driver seat. Longer term I plan to convert to 58x engine management so that I can swap in a 6L90E. With the current 3.73 rear gear it could really benifit from that 4.03 1st gear in the 6L90E, compared to the 2.48 1st of the 4L85E. 2nd gear in the 6L90E is similar to 1st in the 4L85E.





It gets all the beans occassionally and runs out nicely. This is on 93 pump gas, it is noticeably stronger on E85. Not many E85 stations where I have been driving lately though. While it makes power to 6,200, I only spin it ~5,500 rpm for longevity.



Still gets worked a bit too. This was towing a 7,000 lbs tandem axle enclosed trailer loaded to the roof when I moved my mother earlier this summer. It has plenty of power for towing which is what I built it for. I ended up having to ditch the electric fans and put a clutch fan back on it. Duramax fan blade with a Trailblazer PCM controlled EV clutch. The P59 controls the EV clutch as needed, saving power and fuel when it is not needed. The PCM will engage the fan clutch in response to ac pressure and engine or transmission temperature, keeping all the vitals where they need to run. Very important piece of the puzzle when you are running a high compression engine for a tow rig in the heat of Texas summer. The fan noise makes it sound like the engine is screaming, but it is only in 3rd with the torque converter locked, turning ~3,000 rpm on that climb.
