Nice results but;
That is not THE "El Torro" cam. The valve events might be similar but that is a copy. Nicely done, good trq.

Well I'm sure it's very similar, just goes to show how well it works. I'm more than pleased with it. It has tq everywhere and pulls hard to 6,800. Hats off to you sir. If it were a perfect world I would have liked the cam to be a 230/232. Who's knows how much it would change things, but I feel like it would be the perfect cam for a street/strip car. And I equate the tq a result of the compression increase. The car feels torquier right of the get go, which is weird when adding a cam, you expect to lose some.

Thank you, as I said, it must have similar valve events. my original is on XFI intake and XER exhaust.
I run a variation of it (see sig) mine got cut at 232/228 .612, .588 110-1 LSA
The original El Torro is 232/230 .612, .592 111+2 LSA

I didnt know the original El Toro was a reverse split? Thats really cool. Predator how does your setup perform? What heads did you use and what kind of number did you make?

PREDATOR-Z

Advertised specs are 230/230, but once it is cut it will come out as 232/230. XFI intake lobe most of the times cuts at 2* bigger than advertised.
472rwhp/426rwtq, pretty similar power curve than in above graph. Pulls to 6800+ but I shift at 6600. Too much trq down low, it is a tire frier for sure. No need to clutch dump at 5K rpm to have eyepopping acceleration.
The heads I used are Cartek 243 4X milled to 59cc.

thats great numbers i can't wait till next saturday when i've got some dyno time booked to see what i've got out of my set up with a eps 236/242

nice results...i had a set of the livernois stage 3's a while back but didnt run them cuz i had them milled to 59cc's and decided i didnt want to flycut. Before selling them i flowbenched them against some other heads and made a thread about it on here, they actually flowed what they claimed which was good considering i flowed a very popular competitors set of ported 5.3's which were supposed to flow over 310 cfm and they flowed about 20 cfm less then what they claimed. I may pick up another set in the future because from the results i have seen they are great heads for the price.

Where did u get that cam from? Is it like a costum grind EPS cam?

what size cam were you going to go with that you would of had to flycut?

it was a 230/234 cam..dont know if i would of had to flycut for sure but im pretty sure i would have since they were milled to 59cc's. They were good heads though like i said flowed what they claimed and actually slightly outflowed the afr 205's i ended up putting on the car.

Awesome numbers OP. I have Pred-Z's original El Torro and i absolutely love it. Its a perfect street cam.Won a lot of races i shouldnt have because of the broad powerband it makes. Now we get to see how it does with boost.

OP, just wanted to clarify, you did NOT need to flycut with those heads milled to 61cc? Ive been looking at these heads and was trying to decide whether I wanted to mill them or not. Im running a 230/232 592/295 111 comp cam.

I did not flycut. The guy I bought them from on vette forum says they were cut .030 and I resurfaced and he took .004. So roughly .034 I what I know... This put me right around 59-60cc. He ran a tsp tv2 with them and he measured and said it was tight but ok. My cam is smaller with 1* less OL. So I said to hell with it. Lol kind of irresponsible but it worked...

ok, I was planning on going 61cc so I imagine I would be ok with the factory head gasket? My real concern is the piston kissing the intake valve as it starts to open with the cam on the 111 lsa.

Yes. OEM MLS gaskets..

Cool, thanks for the input and feedback on the heads. Ive been looking for an "affordable" 243 head that made good low end power and torque since my car spends 90% of the time on the street and I really dont care about heroic dyno numbers.

Would these numbers equate to a 2002 Trans Am, or would they be lower? Also, who specked out the cam and was the cam designed around these heads. Lots of AFR/TFS headed cars are not making that much power and torque with larger cams.

Great numbers!
Now for the icing on the cake post up a idle clip!

Phoenix, I think they would be lower by how much I dont know. Im pretty sure our 4th Gens have more of a drivetrain loss than Vettes do.

Yeah, I think you're right. Just trying to figure out what the numbers would be on my car. Would still be very impressive I'm sure.
