Dyno Day
Tomorrow it's going on the dyno. Not sure if he will have time to run it in or do any pulls until later but the time is near.
Here are the details: 468 cid Edelbrock 87 cc D ports (unported, but cleaned up) 9.94 CR Butler/CC Hyd roller 236/242 @ .050, 520/540, 112 lsa 1.5 rockers factory intake Calibrated 750 cfm Qjet by Ray Klemm For the exhaust, we're gonna do some pulls with a set of headers, then with RA manifolds that have 2.3125" collectors to 2.5" Pypes down tubes. It would have been great to have a set of 2.5" manifolds but apparently that's not gonna happen. If anyone wants to make a guess at numbers, I'd love to hear what you think!

Boy, that's being pretty stingy with the ponies. Not even 1 hp per cid?? LOL.
I'm gonna say 485/550 with manifolds and 500/565 with headers. Also, I don't know anything about the dyno, whether it's generous or not.

It's been 9 months! Didn't seem that fast to me... LOL.
That's OK. The finish line is in sight.

Looking forward to this one! Similar cubes, same cam and carb. Big difference is the higher compression and aluminum heads but it should give me a ballpark for my build.

Again, as mentioned before, don't let your dyno operator stop the pulls short of where the combo makes peak power !

425 hp at 5252 rpm. All you hp prognasticators must have an rpm tied to your prognastication, otherwise invalid.

west coast vs east coast continues...

There is no West coast vs East coast quarrel that I'm aware of. It's just simple math that puts everything on the same playing field. Anyone that's actually had an engine on a dyno knows how this works. Ask anyone that lives in Colorado, they are familiar
If you're not familiar or just simply refuse to believe that elevation and DA matters, then bring your stuff out here and run it, or dyno it, I welcome it. But don't say I didn't warn ya when you're all disappointed your car slowed down or your engine doesn't make the power you think it should. Last edited by Formulajones; 09-09-2022 at 05:27 PM. |

From going and viewing what those heads your running flow out of the box at your .520” lift, your motor could make 510 Hp, but that stock intake will keep you well below that, especially with a cam which has under 252 duration@ .050”.
