That cam is small for a blown 408. With the nice heads it's probably 475 naturally aspirated. Approx power level: Boosted HP = NA HP x (boost pressure + atmospheric pressure)/atmospheric pressure. 475 x (10+14.7)/14.7 = 790 HP. This is idealized so you have to factor in things like...

Ok being a rear sump pan that makes more sense. Still looks lower than it probably is probably a camera angle thing. Nothing but accolades on your build though. I hope that between kids and my business I can get more time to work on cars one day.

Ok. Seems like with it being near the bottom of the pan it would push oil up directly into the can if pressurized. Maybe I'm seeing the pan connection wrong.

What does the catch can do to reduce crankcase pressure, or is that just a better way to evacuate the ventilation from the valve covers?

Very interesting. Thank you for doing some experimenting and publishing results. What's the difference between this and installing a larger valve and offsetting the location by (half) the increase in diameter?

@subcom great post. As always your content is great. Thanks for this. Real information vs. pure speculation.

I bet a hemi short block with forged pistons and aftermarket rods would hold up just fine for a long time with the right tune at 1500 hp

I mean, That's gonna be the same either way.

I mean, with some reasonable upgrades you could take a stockish hemi to 1500 with a nice turbo setup. You wouldn't need to spend 10k.

Obviously lighter reciprocating components will help with how fast/responsive an engine is. Lots of other factors come to play that are also important. First and foremost, for an engine to rev up fast, against the weight of the vehicle, the engine needs to be powerful. Matched gearing and...

Why stop at 150?

I don't think guys are stupid. But I do think a lot of guys are ignorant and/or stubborn and hanging onto old beliefs. There was once a time when I, too, believed a short stroke equates to a revver. I was ignorant. I saw a lot of not exotic builds proving the contrary and realized I was...

Sooooo much BS information here. The whole idea about short stroke engines being "rev happy" is straight bull****. That's a myth that's been completely debunked. An engines ability to rev has much more to do with cam timing, carefully matched valve train components, and head flow capabilities...

4.04-3.91=0.130 Maybe use a calculator next time

A 340 short block, equivalently built, would probably be a $500-1000 premium compared to a 318 or 360 based engine. The $2k is overblown. Ironically a 273 probably would cost more because of the specialty pistons required.
