Guess the horsepower....

How do you think these TFS heads compare to say Edelbrock cnc heads or the BBM versions with the same short block/camshaft and intake manifold?
Are the TFS heads further ahead in making power over the other cylinder head offerings?

You have had as much experience as anyone wrt FE builds. Are these heads better or just as good as other offerings?
I am sure you have an educated opinion.

Cheers

thats what i been wondering.it would be nice if someone had the time and money to compare heads.you could throw a set of bbms or eld-cnc heads on and see what the diff is.  somebody will one day.

Thank you Brent, nice build and I hope you and your wife get to feeling 100% soon.

I can’t help but think the relatively small intake ports on these heads ( for the hp they are able to make ) will make for a very fun responsive engine.

How did peak torque come out?
The Gonkulator was about 40hp low on both corrected & uncorrected power so that says a LOT for those TFS heads.
They seem like about the best out-of-the-box heads yet.

Then again the FE came out 60 years ago, its about time!

I think they're pretty nice too, but could probably stand a smidge more volume for larger engines pulling higher rpms.

5000 rpm torque peak.

Very nice numbers, the rpm for peak HP surprised me, I really thought it would come in around 6800rpm or so. The small ports hang in pretty well to let it RPM, and obviously the tunnelwedge has no problem supporting the heads up top.  Nice spread between tq and hp peaks, engine should be fairly flexible. 

[WerbyFord]

Okay, 5000 rpm, uh, what was the torque at that 5000 peak? (Corrected &/or Uncorrected)?

Sorry Werb, I thought I listed it.  I put the video up on my IG page and listed it there.

It made 595 lbft, corrected.

unless I missed someone it looks like mn67 is the winner. 67Fairlane was right on but went over by .5   Thank God I didn't win, I don't know if I could have afforded it.

As much as I like goodies it is hard to argue with a .5 hp guess. Brent please feel free to send the swag to Mr. 66Fairlane. Unless of course you are in a giving mood and the prize is your new rocker arms.

I was just in it for fun, I think the freight to Australia would be worth more than the goodies! Quite happy for you to grab the goodies Mike.

I was a fair bit out with my rpm (which was just a zero added to the hp anyway)

[cjshaker]

Since nobody wants the goodies, send the T-shirt to me, Brent. I'll wear it, even out in public, despite the fact you stole all the 660's
