So If im reading this right, my Z06 would like the "El Toro" cam with lg super pros, no cats and borla stingers and be reasonable to drive with a proper tune? And by reasonable, I mean as a dd and not have surging or bucking issues in parking lots and traffic? Im also ready to order a cam. What specs do I need to have it ground?

i'm looking at gettin the El Torro, a few questions first. how do i go about ordering it? lol since it's predator-z's spec i was gonna try to get a hold of him but last i checked his PM has been disabled so i'm wondering if TR has the cam on file somewhere or something and the second question is i though i read somewhere that the el torro cam 230/230 is a reverse split, i can't find where i read it and i'd like to see if i read the right thing. i know when reverse split is said people think of TR230/224 or TR236/230 so to me in my mind a 230/230 is a traditional split. hopefully predator or someone else can confirm or correct this

It's been hinted that it might be worthwile to use a later IVC (even at the detriment of DCR) to gain top end power. It's obvious that a later IVC allows more filling time at higher rpms, what is not obvious is what rpm range equates to which IVC, and how this changes between a 370 and 427? Any insight to the non-obvious would be tramendously appreciated!

from PAtrickG regarding a 346:
"I like to decide where I want my motor to make peak power first. 6000 rpm peak, I'll choose a 40 degree IVC. For a 6300 peak, I'll choose more like 45 degree IVC (ABDC at .050")."
Some say that the IVC/intended peak power range are related to the percentage of cylinder that are left to be filled when the intake valve closes. In which case comments like Patricks above would hold true for all displacemnts.
from Kevin Shasteen on hybridz:
"If you want a streetable engine with a relatively smooth idle in the 700-750 rpm range you will need a cam that offers an IVC that leaves atleast 75-80% cylinder volume after the IVC.
If you had a Crank Angle Chart you would see that 75-80% Cylinder Volume would require an IVC somewhere in the 61-70* (@ 0.006”) IVC ABDC range[with a 230 @ 0.050" xer lobe this would be about a 41 IVC ABDC]."

Check out this link!! another guy with the MTI X1 230/227 reverse split just put down 411/390!!! stock 243 heads and LS6 intake. imagine if he had some ported LS6 heads or even some TFS 215 and a fast 92/92..thats big power for such a small cam. to prove again that reverse splits do work...or should i say retard, band -aid cams..LoL!!

So i recently finished swapping a 01ls1/t56 into my s10 and im already debating on what cam to go with. I know the ls1 is gonna stay cam only so im leaning toward the tr230. With just bolt ons the truck went 12.6 at 110 last week. I was wondering do you think the tr230 would be enough cam to get me into the 11s or should i go bigger. btw the truck is my daily driver.
