“econo” porting. CRITICAL AREAS

[@wayneskelly308]

Pump gas 408sbc made 627hp and 560tq with a set of Chad Econoported 210s.

[@SpeierRacingHeads]

AWESOME!

[@TeamBookem]

Any videos?

[@edsmachine93]

Nice work Chad. Certainly a good approach to making a set of heads work. I had watched this video before. Not sure if I commented. Showed up in my feed, so I watched it again. Have a great day. 👍

[@justinschmidt9180]

Great video good job man

[@patrickoleary6379]

Damn man. For the money I would bet it's one of the best going. I would bet you could see decent power gains, dep on induction and fuel systems. Quite cool man.

[@davidwood1923]

I Do My Own Porting on Small Block Chevy Heads... Looks Like You Know Your Stuff and Do High Quality Work. Thanks for Sharing

[@hotrodray6802]

80% of gains come from the first 20% of the work 👍👍😎

[@gordocarbo]

Aint that the truth.

[@glenbrannon7224]

Very nice , wish I knew about you before giving Dr J my money on SBC heads.

[@gordocarbo]

Did you get them back?

[@rchardsmith605]

2 Questions how do you burr finish and how much of the guide has to stick up into the bowl if any. Thanks

[@stinkythingsdotcom]

Love those Air Fresheners !

[@DragBoss351Cleveland]

Looking Good Chad. Great work for the money 👍

[@SpeierRacingHeads]

Thanks!

[@trailerparkcryptoking5213]

Nice looking work/price! 💪

[@phantomfox9093]

how much for eco port job of gt40p heads ??

[@Moparmaga-1]

Do you burr finish chambers and if so what kind of power numbers could be gained?

[@brracing7861]

Good Stuff !

[@SpeierRacingHeads]

Thanks!

[@gordocarbo]

What do you recommend to take my 383 to the next level? 18 or 15 deg heads? which do you prefer? dont keep up on whats out there cant afford a bigger block Wanna do this! Bought a 300-110 on your posts yrs ago. Hope it outperforms by end to end ported 7530 Team G

[@5PYZ3R]

could probably also call it like "street" and "race" ports. econo doesn't seem that marketable hahaha. Awesome video thanks

[@lawrenceskrobarczyk4402]

Amazing price 👌

[@bradmcgrath358]

Chad, when you talk about throat %, are you talking area or diameter?

[@tiitsaul9036]

“Square the openings” what does it mean?

[@hotrodninja458]

Nice work 👍🏼 Question: Can you blend the angles on the seat instead of sharp angles? For example, the only machined surface will be the 45 angle cut.

[@flinch622]

If you are saying take a radius [pure or variable] and only cut/stone at 45 to accommodate seating of valve, there is the issue of getting that seat on the valve where you want it, and that varies street to strip. It maybe could be done, but might be more trouble than its worth? Indexing cutters could be a p.i.t.a. I doubt you could get at much of a performance difference vs a 5 angle.

[@gordocarbo]

Cuts/edges are there for a reason leave them be.

[@Schlipperschlopper]

Sadly soon all combustion cars, bikes including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime (BABVVOBundesabgasbespassungsverbotsverordnung)!!!!!!

[@SpeierRacingHeads]

How about this, Fuck California and New York. It hasn't happened yet, nor will it.

[@gordocarbo]

@@SpeierRacingHeads Hope not....Edison is raising elec rates like frigging crazy in anticipation of all the EVs...gas is stupid high....In Commiefornia. Not even in a good area low income chitsville. Premium 91 piss is about 6 a gal now.

[@martyjohnsonozarkoutdoors8198]

I've thinking about trying a set of those heads on my next engine. 4" bore 3.75" stroke. Smallblock chevy. I just want a good torquey engine for my daily driver 84 chevy 4x4.

[@SpeierRacingHeads]

I'd look at the 195cc head.

[@martyjohnsonozarkoutdoors8198]

@@SpeierRacingHeads Thanks. That's kinda what I was thinking too.

[@mikef-gi2dg]

Wow...nice video...I actually think I understood almost everything...except the 91.5?

[@hotrodray6802]

Throat diameter to valve diameter. 91.5%

[@mikef-gi2dg]

@@hotrodray6802 Ahhhhh, I see....thanks!

[@SealofPerfection]

91.5% means 91.5% of the valve diameter?

[@SpeierRacingHeads]

yes

[@TheProchargedmopar]

New sub, Thanks 👍💪

[@boharris8179]

Bro that is really your race port just open most everything up another 8 to 10 hours of grinding...

[@paulferreira9060]

Chad what’s the turn around for econo job ?

[@SpeierRacingHeads]

I'm hammered. March'ish
