Indy, Bill Mitchell, and Keith Black make aluminum blocks, Callies now makes iron in both Hemi and Wedge configuration. 440 blocks get iffy above 600 hp, 400 blocks are usually good to 700+, some thick 400 blocks are good to 800 hp. Aluminum main caps will help with the main webs, I have no experien...

I gotta admit, that's funny!

No plans for a 440 Chrysler or an FE ford. Yeah but think of the literally tens of sales you're missing out on. That is hilarious... I bet you would sell a lot more than "tens" If you would produce a 400/426 Hemi/440, that are almost the same block. Once again, no love for the Mopars. :(

The one spec I'm missing is actual measured port CC, I've been estimating that, didn't realize it was that important, thanks Larry!

Also, the program doesn't actually run your cam inputs but, gives the best cam timing and lift. Is there anyway to run it for power out put, using your cam inputs so, you can see the power difference? PipeMax v4.70 just predicts the Cam Specs that should work for your desired RPM you can compare yo...

A proper valve job with a back cut intake valve will give you most of the benefit of a 30 degree seat without any of the headache.
Or expense, as you need a good valve job anyway.
Those heads and valves are oddball compared to normal BBM stuff, so replacing valves could get expensive.

Thanks for the update!

The only thing that I can compare this to is that I'm redoing my lil' SF-110 w/ higher capacity intake motors. In order to have more flexibility on vacuum motor speed -- and also not have to run them at 100% at lower lifts --, I'll be running the power through a Variac to let me dial down the motor...

Went to a Pertronix Second Strike after my MSD analog box failed intermittently years ago, has been flawless for years. Recently purchased a Digital HP box with matching coil for another project, we will see this spring.

II will say it again: not just about raw airflow. As many have proved. One thing that gets overlooked with E carbs is the incredibly small n/s that they come with: 0.093". Just big enough for a lawn mower. Wonder how many E equipped cars would have gone faster if they had big enough n/seats to...

I ran the 800 AVS on my peanut port 461 back in 2019 and it was only a tenth and a half slower then my 850 Mighty Demon. Mph was down by 2 so with no tuning I thought that was not all that bad for an Eddy carb. That sounds right, a 750cfm carb vs. an 850cfm carb. The Eddy's are great if they are ma...

They may not flow the advertised 800 but they do work well for the correct combo . Most people think they need more cfm than the really do so the gimmick kind of works . Owner thinks the carbs are magic because they are the best driving BIG carb they have used when in fact it might just be the redu...

Just because there is a slight overall flow loss with annular boosters doesn't automatically mean it will reduce peak power. The atomisation, signal strength & distribution needs to be factored in. Absolutely true, if you are not making much power. An "800cfm" Eddy actually flows less...

Got any pictures? If Eddy redesigned them to not murder the flow, I'd be up for trying them.
