Love the graph and numbers for a 128!

What are your thoughts about the woods wm8-408x cam ?

[@Yeetsforthestreets]

Curious what the cost estimate of a build like this would go for on a bone stock 117 setup.

The perfect tq curve

[@chriskuczmarski2535]

Don’t think my 128 build was a sleeper but with 592 cam we was at 145HP 148tq

Can u build this if you have the 107 M8?

[@MoonshineHarley]

Yes! We have several options. Please call the shop at 615-771-7775 ask for Nick or Jamie.

Have to change your rods and flywheel

[@bowallace7093]

How big of a job to take my MHP 124 to a 128? Or would it be more beneficial to go to a 131?

[@MoonshineHarley]

Each cube you add will typically increase the HP and TQ 1.2. So 4 more cubes = 4.8 more HP and 4.8 More TQ. 131 would be better as it’ll increase more.

[@jeromeparker327]

Did it start out as a 107??

[@geraldgoodiii6993]

114

You guys never talk about manifolds injector sizes

[@MoonshineHarley]

We have before. We will again soon. Lots of new parts and build coming for the 2024 platform

[@Yeetsforthestreets]

Recently watched a Q & A and they talked about it a good amount.

Nice flat torque curve

[@My.name.goes.here.]

Torque curve isn’t even a curve really, more just a flat line across the top. lol

[@freedom6919741]

Budget ? 😂 what does it cost 12000.

[@suntryp]

bargain

[@Roaddawg68]

What????? Man poverty sucks.

[@chriskuczmarski2535]

Closer to $20k give or take

[@freedom6919741]

@@chriskuczmarski2535 that’s insane ! I had a crank up build done and a Baker Grudge box installed for less than that. Thats counting new exhaust also.
