Sounds like your competition definitely helped free up the flow of both information & cooperation. Pretty awesome for everyone. Although I'm not a LS or sbf guy & I've said it before, I greatly appreciate your videos. Especially these new challenge/ shootout vids, I find them most interesting. Hats off to you for doing them.
Good info as always. Sure would be great if that BBC was coming sooner. Winter time and the engines coming out of my square body. Heads, rotating assembly and a Powell roller going in. Pumped.
Eric, thank you very much for all your help, time, and exhaustive research, brother 👍 Could you please try a "golf ball" dimpled 1" 4-hole tapered spacer with one side cut out (you'd have to modify the cutout yourself) to resemble an "open" spacer for the open side to go over/on the flange of a dual plane intake manifold with the "open" side of the spacer going on/over the HIGH SIDE of the plenum of the intake manifold with the unmodified 2-hole side over the DEER LOWER SIDE of the plenum.... and try it both ways INVERTED/UPSIDE DOWN and then even switch the spacer by trying the opposite side of the plenum ---- please❓🤔 It would require 4 different pulls on the dyno to be able to test the SAME spacer as it sits 4 different ways on the same intake manifold (dual plane). I'd like to try that on my twin 482cid BBC engines destined for a Marine offshore hi-perf pleasure boat application. I am one of your customers who you rebuilt 4 of my AFR 315cc cnc ported heads for twin 565cid BBC engines for a couple years ago. I drove all the way to your shop from Michigan ---- twice. 😌🇺🇸 Man, sorry about all the heavy and wordy explanation... Hopefully I didn't make it sound too confusing... I just want to make sure you understand what it is that I am trying to get across to you. 🧐😌
Yeah I'm excited to see that too. I'm not a ls guy but I'm going to purchase Google drive link now. It's awesome to see charlie getting some exposure on the bigger you tube channels. 👍
Eric I emailed you awhile back about the price of promaxx SBC heads, I'm sorry for wasting your time I just can't seem to get ahead in this dam economy but I'm gonna get them. Thank you for your time and all you do and the information you share
used to use 16 pen magnets attached to a common length long bar across top of heads to hold up lifters on stock ford style roller lifters not sure if that would work on link bars.
This is great stuff Eric. I am anxiously looking forward to all of the cam challenges. SBF, SBC, BBC. BBF would be great as well. I know it's more expensive, but hopefully you make enough money from the challenges and selling product, that it becomes viable down the road.
I done something similar and on a slant 6 i used to race. Later heads all closed in. I used 12 pen/pickup telescopic tools. Down the hole pick up the lifter a bit hold in place with a clothes peg. Have to be careful not to lift too high pulling out the lifter. Use a sharpy to mark the pick up tool as a gauge.
Eric, why are the cam contest rules so restrictive? The heads @380 cfm on 400+ci would likely easily support 750 HP if the RPM and lift numbers were bumped up a bit. I understand the first round of tests were limited by valve train, but why not let these heads show their potential for the upcoming contests. How about 5500 - 8500 RPM sweep with a mid length runner dual dominator intake? This would be more realistic for a drag racer with occasional street use. Why spend money on good heads, then neuter them with tiny camshafts, RPM's and a small single carb? May as well use stock LS3 castings for around 600hp without even having to get wild with the cam, compression and induction. Sorry, but I'm just frustrated honestly knowing whats being given up so far..... That said you're honestly doing an awesome job with sharing this stuff and an avid fan.
It wasn’t restrictive. Two rules on cam .660 lift 4000-7000. This range is closer to street strip not 8500. Nobody peaked at 7000 and some cams were very large.
Iowa speed and supply has a nice dyno setup if your willing to drive that far and looking for another location, dts. Nice people. His business is listed
Size definitely matters... Would love to see someone do a windsor duel plane with some size. Recently built a 408w with cnc'd promax castngs & rpm air gap. Made 562 ft/lbs @ 4300 and pleasantly surprised topping out at 570hp @ 6200. Feel it would pick up a bunch with bigger intake
Legend had it he really is Superman and he's the best cast iron porter ever
I can't not see that as "cast iron porter" as in like a cast iron janitor. Wonderful
His Magnetic personality will notallow him near iron
Legend had it he actaully specced N.K performance's camshaft but didnt enter because of competition bias
When vortec heads were still cool, he cut one to flow over 300. Thats rocking for a factory casting

Looking forward to the split Holley being tested. I think it will do well. Thanks, Eric!

Mopar guy here. Just donated to the SBF challenge! As close to a Mopar as we gonna get. Lol.
The hope is 2026 to do a sbm then give it away. Maybe sooner but there is a lot going on.
SBC and Mopar are similar aren't they, idk anything about them I just always assumed

Check out Anderson Motorsport, he makes some tools to hold the lifters up so you don’t have to pull the intake to change cams on a sbf.
I'm glad and excited that you are going to test Charlie Silverado's 2 piece intake manifold on the LS. Thanks!
Funny...
@servediocylinderheads yep. I even told him to use it in the cam test.
Yeah I'm excited to see that too. I'm not a ls guy but I'm going to purchase Google drive link now. It's awesome to see charlie getting some exposure on the bigger you tube channels. 👍
@bobbyhaskell2048 Me too!
I’m not big on RUclips.

Do you really need promaxx heads if money is tight?😂
I skipped the beginning,
Was there a warning about not understanding whats going on of I skip around?

I HAVE ALWAYS WATCHED ALL YOUR VID,S FROM START TO FINISH ,,, NO JUMPING AROUND FOR ME ,,, I WANT TO SEE AND HERE ALL YOU HAVE TO SAY ERIC
Thanks man
You would still pick the AFR mongoose over the FED M311? I remember you speaking highly of Frankenstein stuff in the past.
I love a duel plane
Well that's a lot lol um yesh can't wait on more testing and be curious on what the ford likes for camshaft specs would be cool to see
Awesome info brother!!!!
I got those AFR’s from Tony Mamo….. he did a few things to them….. im ready to see how they do

How many dollars per additional contestant do you need?
Dyno is $1000 a day. I really don’t know how long it will take to change the cam on sbf but maybe 4 a day can be done.
@WeingartnerRacing That would suggest the entry fee ought to be $500 or more per cam. $250 to cover dyno time, $250 for the kitty. I'm game, let's go!

Do a trickflow clevor 408. Pretty sure they have a hole for coat hanger as well...
I do the same thing jumping around. Its even bad when i am writing something, i have to go back and reread it because i will miss whole sentances.

I already skipped to the end…just kidding 😂
I have this LSX dual plane intake on my LS416. Torque beast.
Can we still donate to the LS cam challenge?
yes
Yes
When you click to the BBC donation, in the description it says it's for the SBC challenge. oops.🙂
Probably I will fix that
I would like Richard Holder enter.I'll save some money to donate just keep reminding us.
Kuntz and Co SBF heads!
I vote on tricklow TW205
He’s not gunna do 11r heads
My cam for sbf 408 275/282 110 lsa 106 in centerline and pick whatever lift you like I’m betting .725in/.720ex
Can you do a great job
First and second
