Trick flow 270's, Max wedge. The 270’s were worth 45hp over the 240’s. Other than the intake being slightly different, the engine was the exact same. If you have hood clearance, the 270’s are a no brainer.

If you have hood clearance, the 270’s are a no brainer. Mine is going in a truck with a 3" body lift, I could probably run a tunnel ram without a hood scoop. So no big torque drop and did the power peak at the same Rpm?

I was underwhelmed by their results.
Maybe because I'm used to seeing what these combos make with 60 more cubes and metric ring packs, bigger cam etc.

Didn’t lose torque at all. That's good to know. I was bugging Richard Holdener to do this test a while back, so glad someone finally did it, maybe Holdener could do a 500 incher. So the take away is that the cam and intake probably dictate power band more? I should buy a motortrend subscription, but my internet connection isn't that great.

I watched the episode. Torque and HP increased throughout the RPM range tested over the 240's. Pretty good increase.
Now if they would stick a set of ported 440-1s on it to see if there is any difference. B1 or Predators would not be a fair test because of piston change. 440-1 would be a lifter and rocker change but that is something that can happen with the engine still in the car.

Nice article Andy. Did you ever get to test after the intake was worked over?

Dave Yes, the ported intake picked up 25 hp over the cast intake. I think the best we ever made with that 470 was 780 hp. That was a pump gas engine so we had to be super careful with the camshaft selection. Higher compression would've allowed us to make more power. I think we could've gone over 800 hp if we had put a little more compression in the engine. I've done quite a few 270 head engine since then but none have made that much power. Most engines we do are for street guy or bracket guys and neither of them want to break the bank to pick up the last 50 hp in a build. https://www.motortrend.com/how-to/dyno-tested-vacuum-pump-help-engine-make-power/

The 470 that Compu-Flow is building for me will have the 270's. Not sure on the cam yet but we both kind of want to try the trick flow cam. I will be thrilled if this engine is a legit 600 hp. A pump gas 470 with 270 heads and the TF hyd roller cam will make 600 hp on the dyno as long as you use a good intake manifold. Best intake if you want 600 hp would be a port matched TF intake.

Thanks for the advice. I do have a new trick flow intake now but it has not been port matched yet. Nice to know I am headed in the right direction.

I had a 470 CI with 440-1's never got it on the dyno. But best car ran was 8.60 at 160 mph.
I did get my 500 CI, 440-1 with 871 blower on the dyno. 1300 HP 1050 TQ at 6800 12 lbs boost.

Thanks. It cost a lot of money and made a lot of power. The average BB Mopar that we see on the dyno make around 600 hp with TF240 heads and 700 hp with the larger TF270 heads. There isn't 100 hp difference between the heads, the guys with the 270 head typically run higher compression and big solid rollers., The 240 guys tend to run pump gas and hyd roller cams. Over the last several years it seems like there is always at least one BB Mopar with TF heads on the build board. Sometimes there are two or three of them stacked up in the queue. Very popular combination.

A friend finished a short deck BB with the Trickflow 270 heads for a customer earlier in the year. It was a twin turbo deal, no idea on the power, but I don't think it was a big boost thing.
I had to machine the heads for Jesel rockers, they were nice looking heads, a lot better than the Edelbrock stuff I'd seen.

Trick flow 270's, Max wedge. The 270’s were worth 45hp over the 240’s. Other than the intake being slightly different, the engine was the exact same. If you have hood clearance, the 270’s are a no brainer. On top of that they stated "each head step was a 20 hp gain over the previous one" meaning from a 906 to the TF 270's there is about 105HP difference.
