The reason I push to always use the same dyno is so I can compare combinations.
Just as a good comparison, this combination is about 67 hp over the standard 445/hydraulic roller/TFS head/Performer RPM combination that we do. Very stout upgrade.
-
Stout for street compression!. Do you think the slot made any difference on this combination? Did you try any different spacers? Those were the final customer heads and intake, hopefully. Glad they worked well. Joe-JDC

Nice job Brent, very impressive.

Nice job as usual Brent
-
Thanks. The constraints for this engine were that it needed to be done by about 6000, needed to run on pump gas, needed to have enough manifold vacuum for power brakes, and he wanted 560-575 hp. I nailed the first 3, kinda screwed up the last one.
This engine had 13 inches of vacuum at 1100 rpm.
-
he might not mind the plus 40 horse screw up
-
Very very nice.

how does that cam compare to our SBC 18 degree head employee project ? Good numbers regardless

Solid roller vs your hydraulic roller.
I had to use a solid roller on this one due to the constraints that were given to me. There was no way to make as much vacuum as he wanted with this rpm level with a hydraulic roller.

Why is that?
Also, what was the idle like? I imagine it was pretty lopey but thought I'd ask.

It was thumpy, even at ~1100 rpm.
Hydraulic roller camshafts that work well with FE's have a fairly long advertised duration. When you combine that with a higher desired rpm peak, you end up with longer advertised durations than usual. We can only lengthen the LSA so much without having to go to a $$$ custom core, so trying to hit 13-14" of vacuum in this scenario would have been an exercise in futility.

question,i forgot what the benefits of the plugs in the lifter valley are.can you tell me more about them? never mind,i just read an article on this aubject

Just a follow up....
Always nice when customers provide feedback/photos/videos.
In this case, he sent me a nice video... Crank up the volume.

She's a runner!

Can’t get tired of that!

I like it

Customer sent me a little more footage this weekend. This is the Mustang against a 500ci Charger.... A little traction limited on that 2nd gear hit. I love it.

Brent, where do you get those hose barbs with the internal hex drive?

I'll have to dig that up, not sure off the top of my head.
