So how much do you gain?

If all you do is increase stroke, hp remains about the same but peaks at a lower rpm. Tq will increase pretty much in proportion to the displacement increase.

 

[pishta]

That is correct, the ultimate HP is dictated by the head. Its where in the power band it is produced...More cubes means lower RPM power band and more torque. Think slants. Same head, 3 different displacements. Check out a 273-2 and a 318-2. Lots of improvement with 18% larger displacement

We find significant HP increase with our 408 Strokers IF you have
good flowing heads that will sustain the increase!

 

[pishta]

stock 4.00 bores with a 4.00 stroke is about a 402+

My 360s are all very early blocks (34xxxxx) and sonic checked
I go 030 040 060. All easy to find rings for in these sizes.
I will l have some passes for Winters' in a couple of weeks
if you want to hang out with us = we will be running 4 Mopars!

Part 2: Upgrading the Stroked Mopar Magnum

The video keeps going kuput after ever commercial break. It’s bad enough they slam me with 5-6 commercials but then it states I’m not worthy!
I have not gotten passed them rolling it into the dyno room.

 

[rbkt65]

they have 4 commercials per break. i tried to watch it here, but they want me to take my ad blocker off. NOPE. watched it on my phone. had to watch commercials but oh well.

410 gained 26 hp over 360 but I’d guess most if not all that gain was from increased CR. Didn’t even shift the powerband much lower.

Be a dang good truck motor.

For people that want to run 3.23 or less could see a mild stroker a good build for them.
