Well, after spending a couple months this off season putting my new engine together, I'm hoping to get it on the dyno this afternoon. It's a 496 stroker, Gen 6 block, Brodix race-rite heads, 4130 forged scat crank, mild cam, forged rods, pistons, roller valve train, the whole deal. 9.4:1 compression, mid-grade safe , with a worked Holley 850 sitting on top. Excited to see what kinda numbers it puts out. It's built on the safe side.. Any guesses? And the rubber fuel line isn't going to be used...

580hp, that fuel pump may not be up to the job though

Ya, I have my doubts as well. That's why I pulled the impeller housing off the back to run on the dyno and see if I'm getting the fuel pressure I'll need.

cp performance sells an upgrade for that pump which will work well with your application. I have used it in two boats with up to 600hp and it maintained pressure

I've always wanted to know, what's the difference between a 496 and a 496 stroker ?

Good luck on dyno day.

Thank you. I don't know anything about the 496 mag, but a 496 stroker is just a 454 bored .060 over with an extra .250" of stroke. So a 6.375 rod

Might want to double check that rod measurement.

Short rods make more torque and make up some for a restrictive inlet tract. Although a 4.375 rod would be a little severe.

Haha ya. Oops. My bad. I'm on my phone

Does the same hold true with a 383 vs 383 Stroker ? IE: WHat's the difference ?
