"Have we got a package deal for someone"

We have a new complete Jeep Cherokee XJ setup to convert a 91-95 OBD1 to Haltech R3. With this setup you can "supposedly" control the AW4/A340 transmission.

The engine side absolutely works just like it should, with infinite amounts of tuning capabilities. I Keith Newcomer, have had enough of the transmission side that supposedly works, that doesn't, atleast for us. I've lost money, added wrinkles, more Grey and lost even more hair over this project.

For our customer the OBD11 setup is the way to go and it's getting wrapped up now so this one needs to go to a new home that can appreciate all that it can do.

We upgraded to Syltech dual feed sensors for both pressure and temp in one sensor for, Fuel, Water and Oil, PRNDL converter, our Billet rollerized cam synchronizer, coil pack, knock sensor, Bosch wide band, etc.

This system runs the stock 99-06 coil rail for tight spaces. It has been spliced into the stock wiring harness and fuse block.

You will get everything but patience, we are fresh out of those at the moment.

$4,000 and that's a steal, believe it or not.

The Horsepower Monster is at it again and covered our chassis dyno tuning session on the Jeep 4.0 five speed swapped 1966 Rambler American 440 project car.

The next video in the works is the transformation of a 1966 AMC Rambler American.

We will be sending this ole girl back to her roots with some spicy 4.0 action by removing the SBC V8.

Finally, the 258 build is live and it's a long one with all the inside details.

Building a 258 Stroker We're taking a big step up from our last 258 motor for our customer, Brian. Watch to see us grinding, building, and putting this motor on the dyno to see how...

Billet cam update:

Cams are supposed to be shipped out to us next week. We will go through and prep them all, then start shipping out orders.

***Effective immediately***

Newcomer Racing Inc will NOT be selling, building, CNC or hand porting Edelbrock 4.0 aluminum heads moving forward as of 04/28/26.

We will be using at this point iron only heads, either factory or aftermarket. We have lost way to much time, money and patience to continue down this path.

No one is making up cracking issues over here. Most come out of the box with cracks around the guide bosses if people actually checked. Eventually they crack across the deck at different points and spew water. If yours has been great and no issues then good for you, we can't hope that the next one will make it the distance. What exactly is the distance? 10,000 miles, 100,000 miles, one year, 10 years, 10 races, just roll the dice.

We are beyond tired of trying to explain to customers about someone else's quality issues since day one and we have nothing to gain at this point. We have invested in a CNC program, tons of R&D and dyno testing, which would not make any sense if we didn't have plans to move forward with this product.

There will be a few upcoming builds that utilize these heads, then that will be a wrap.

Brian originally picked up his crusty 1989 258 off Marketplace as a suitable build core.

Today he's picking it back up after we completely transformed it from a crusty 100hp pig to a killer 258 stroker. We also wrapped up the footage on his build for our YouTube channel.
