Title: Newcomer Racing Stroker Build
Post by: Taylor on September 30, 2020, 09:53:43 PM

For those interested in high HP and Torque check these engine builds out. Newcomer Racing in NC.
The first video shows how he builds a powerhouse with off the shelf parts and sealed power cast pistons. Using a 4.0 block From a ‘97? A ‘81 or newer 4.2l crank and 70’s 4.2L connecting rods.

Newcomer Racing's work is top notch and he really pushes the limits on the 258/4.0 engines.  His all out 4.6 stroker build engine dyno-ed at nearly 400 hp (gross).  I'd love to put one of his engines into one of my AMCs but he doesn't give them away for free and I'd have to seriously modify my drivetrain to handle all that power and torque.  Hopefully someone down the road goes this route and shares it on here so I can live vicariously through them.  I also hope he begins selling his high flow sequential port fuel injection kit.
