I just looked it up and stock Cadillac 500 cylinder heads normally flow in the mid 200s. I'm happy to see this company still doing well.

[@BEANS-O-MATICtransmissions]

About 25 years ago, i was obsessed with wanting to building a 500, i was fascinated with the stock amount of ci and obscene amount of torque that could be made. Can't wait to see what it does with these heads and a decent cam.

[@DSRE535]

BOPC is my wheel house, I’m glad to see some finally come through your shop!

[@anthonysgarage]

I would love to build a Cadillac big block. Gotta finish the Buick first. Seems like it’s much easier to start a project than to finish one.😕

[@shakinbottles]

😂I have the 500 it was perfect untill it stopped working 2 weeks after I bought it now it my project it does have amazing torque tho

[@juansandoval9282]

I live in Santa Fe, and have had Courtney dyno two of my engines, and I agree with you that he is very knowledgeable and an easy guy to work with.

[@dondotterer24]

Cortney makes some good HP with the stock heads. Can't wait too see what these do its going to be impressive.

[@blown572hemi]

I like caddy engine's. I like the valve layout were exhaust port's aren't side by side in the chamber. 472-500ci that weighs a little bit more than a small block chivy

R.I.P. Courtney. He did so much for Caddy development

When did he pass?!

Interesting work on a lot of cars over the years

[@xlr8r3VA]

A while back Edelbrock made some Caddy heads, they may still be in production. However, they are not anywhere near as nice as these heads! Great job Eric!

[@jcnpresser]

It’d be cool to see some olds heads. I think it’s neat seeing these older bopc stuff.

[@icetech6]

Believe me... us mopar guys would LOVE to have better heads.. just ordered a set of TFS190's yesterday (4 month wait) and for $2200 i would like a better chamber, but at least TF tried to improve it :)

[@davidleary823]

Great details. Makes me want to buy a Caddy!

[@timothybayliss6680]

The first thing i noticed was how good the chamber looked

[@crazycoffee]

I love TH425s. I got my Toronado. I hope one day to get an Eldorado with a 500ci Caddy. As well what do you think of 455 Oldsmobile heads? Do you think the exhaust crossover gives it that more tractor like sound?

[@mcss-ll4yg]

Big block caddy = lots of torque!!!!

[@johnnyboyssite]

first thing i noticed is that all the intakes resemble a "bad" port on a BBC.

[@jmflournoy386]

Weld up those intake chambers?

[@rotaxtwin]

Heck yeah, those are some nice castings and you made those chambers beautiful. I'm not aware of much for Caddy intakes but there must be something out there beyond a Performer.

[@KingJT80]

they make those too i believe. i know theres a single plane somewhere

[@Driftyboi594]

Definitely interested in a set for my build

[@johnb7430]

What did you use to fill the port floors? Splash Zone epoxy?

[@scottk2342]

How bout doing a Pontiac CV-1 head…

[@xozindustries7451]

Very cool motors, will your customer be dyno testing this motor?

[@patrickwendling6759]

Thank you for your knowledge 💪🏽

[@4339jk]

Let Courtney know we need a Mopar head like this...

[@secularsunshine9036]

*Let the Sunshine In...*

[@Richardsalazar32]

arethose heads available now

[@kevin2960]

They have made well over 900HP natural so far. I don't think they jave broken 1000hp all motor but maybe i missed something.

[@rolandotillit2867]

You may not be Superman, but like the saying goes, Superman isn't brave. Keep up the good work!

[@timothybayliss6680]

Right on

[@johnsheetz6639]

Now if they could just cast some short blocks at a half decent prices

[@slowbird9]

Too bad you don't do Pontiac heads. Interesting that you do Cadillac heads.

[@timothybayliss6680]

I think someone sent them in. I imagine eric would do a Pontiac head if someone wanted it done

[@WeingartnerRacing]

This customer paid for the flow plate to flow the heads. No Pontiac guy has offered. I would then do aluminum Pontiac heads.

[@shonandmeshalee1691]

I have a 72 Cadillac sedan DeVille. Ate you accepting new work

[@WeingartnerRacing]

Yes but not Cadillac at this time.

[@shonandmeshalee1691]

@@WeingartnerRacing I was wondering if you would do my 472heads

[@shonandmeshalee1691]

@@WeingartnerRacing I want em ported too

[@redchris97]

I always thought the Cadillacs had good potential, but there's no heads for em' and no cams either, Glad to see this is being done.

[@redchris97]

@@scotthatch4548 I disagree, having 2 sets of cylinder heads on the market is not exactly parts availability, however I'll admit to you I didn't knew they had cam options, I remember a few years ago summit racing only had 1 cam grind listed for the 472/500 Cadillacs, but that was several years ago.

[@scotteric8711]

@@scotthatch4548 Yep. Summit is a chain store dealer, just like ol "trek auto" but in bulk. Come to find out another widely known (Now belly up) company used many off the shelf and modified parts from Oldsmobile and Dick Miller Racing. Even Howards and Isky make plenty of bump sticks for the cads. Joe hunt is still building magnetos too!

[@KingJT80]

@@scotthatch4548 kind of like the buicks. TA performance youre not opening up a summit or jegs catalog to get a lot of the oddball stuff

[@baby-sharkgto4902]

Damn nice heads. On a different note I would like to bring something up, just because you don’t like LS engines doesn’t mean all guys with LS engines are assholes. I always hear you being snarky talking about those “LS guys” meanwhile I have not really met one. I often hear you talking crap about LS engines and LS guys though. I would imagine the LS boom must have brought you a shit ton of work.e

[@WeingartnerRacing]

I actually like Ls engines and heads. I just hate the fanboys that blast false info about other engines. There is a difference If you don’t see it just post a question on a forum about how to make a sbc or Bbc better and you can almost guarantee someone will say Ls swap. Ls customers don’t bring me work because most, not all , are too cheap. They spent $800 on a junkyard engine they are not spending $800 for head work. Again I don’t dislike Ls engines just many, not all, of their fans.

[@baby-sharkgto4902]

@@WeingartnerRacing ok I totally understand, it’s like me with ford. I like ford a lot but I usually do not like the Ford owners 🤣

[@scotteric8711]

@@WeingartnerRacing Hit the nail on the head! Someone mail this man a podium. I'd love to see the fan boys reaction to the '09-14 production LS engine ring land drifts in machining and the '13-16 AFM engine problems.. They are just like every other engine to endure their share of imperfections.

[@gordocarbo]

@@WeingartnerRacing Same here, they wont pay for any porting or even machine work I quit bothering with them yrs ago. Most are clueless and repeat garbage they read off the web.

[@gordocarbo]

@@scotteric8711 Amen to that. Time bombs waiting to happen....02 5.3 I bought new...never had the valve covers off before it was stolen at 180kish. Good engine but too big of cyl head horrible throttle response and even with 3.73 gear it wasnt a true truck engine in my opinion

[@billythebake]

What about sinking the intakes, then running lash caps on the exhaust valves to put the tips in the same place? If this doesn't FUBAR the rocker geometry, that is...

[@stuffandjunkandthings364]

There is no "Probably"- they suck.

Are you aware the Spectre Streamliner set a land speed record with the cast iron heads? People that know what they are doing have made 600 hp on them..
