Put some injectors on that bitch and then I'll guess 400whp.
I've been doubting this set-up as it seems everyone never gets what they want out of the el torro cam unless everything is perfect. No matter what the master of valve events on here says this cam isn't for everyone.

Funny that when done right, it works as expected
Poeple in general seem to think that cams are magical and just slapping one in will get you where they hope.
Then poeple take shortcuts (no degreing, no preload check, no right tuning etc....)
It is pretty simple, put the time and effort, do it right under the right conditions and it works as it should. It ran 10.6 in the 1/4, cam only.
If done once, it can be duplicated.

I've heard you brag on this cam for a long time and chris is the perfect example of doing it right.
We've come to the conclusion that it takes at least 1 7/8" headers, a 3.5-4" quality merge along with a quality mandrel bent ORY and at least 3" exhaust if not 3.5" or TD's to hit 425whp. Of course every N/A motor's exhaust system should be set-up this way, but not a lot of people have the money to do it like that. We're talking 2500 on just exhaust on the low side here for what I just laid out.
I've just personally seen the 224/228 or 228r cam make just as much power or more and be at 400rwtq. also with 1 3/4" headers, LS6 intake, ORY, cat-back, lid, maf, etc. etc.
I'm not downing the El Torro at all because it's a great cam, I think some people expect to much out of it though because of what chris has done with it, but he has a lot of little things that make his set-up what it is.

Optimising a setup takes attention to detail. Research Tony Mamo's AFR205s/224/228 combo. Not too many poeple reached his goal, why? Because Tony spent probably dozen of hours in fine tuning his setup. Same thing applies to all cams.
As far as it needing 2500$ worth of exhaust, that is not true, it does need a free flowing exhaust (obvious looking at the exhaust duration). It does prefer Corvette setups, after all I did make it first and foremost for my C5
Chris is meticulous and creative in his moddings, so he gets rewarded.
In general, where my life is concerned, I always believed that if one does things half ***, one gets half *** results.
After all, it is still the smallest cam in the quickest advertised 20 top cam only on this site

Pred, in your opinion, which would be more beneficial, going from
1 3/4 to 1 7/8 Headers
or
LS6 to a Fast 90/92/102 manifold
IE, if I were to throw more $$$$ into my car with this cam and my stock 243 heads, which might produce a greater result, or would they be somewhat the same?

will yield best results. Look above for rmtt graphs with 59cc Cartek 243s (stage 1), but if you go 59cc you'll need to flycut .080. On my C5, I gained 43rwhp peak without flycutting with 61cc, PTV was .07 on intake.Intake will then shine after that, but cam only, intake change benefit is minimal. I kept my LS6 intake, but Chris had low returns on intake swap.
rmtt got 58rwhp from heads and 90/90.

This cam was never designed as a drag cam. I put it together for Street performance. it does need certain parameters to reach its potential. It strength is its average trq gains in the curve. Most enthusiasts look at peak numbers to evaluate cams. I don't. I look at the useable power curve from 3k rpm and above.

I'm just saying it's not for everyone like every cam isn't for everyone, but if done right like anything it will shine like you said under the curve, and people won't look at the low peak and say what happened here?
Chris took the torch and ran with it to the fullest in his set-up. If everyone could do what he did, there would be no doubting the set-up like mamo's 224/224 and 224/228 set-ups.
2500 might of been a stretch but, for ARH 1 7/8" LTs, ORY, Merge(vibrant, etc.) and a 3.5" or 4" cat-back and you are at least at 2k almost brand new, which could be had a lot cheaper used obviously.
I love reverse duration cams in the right application, like it's been argued in turbo apps with manifolds vs. headers and deciding on how much split and which way the split should go in those applications, but that's another subject.
I hope the op can get his set-up running like it should. I think once the injectors go on you will be perfectly fine.

idk if this was mentioned but are you sure your valvetrain is correct? I have stock 99 heads (853s) and run 7.425 length pushrods with the el torro.. Im not sure on the details/setup of the prc's but its something to measure and make sure its correct. it just caught my eye cus we have different heads but same length pushrods(not saying its not possible though).

well i was under the impression that 7.425 would work with the 62 cc prc 2.5's but i have been thinking bout purchasing a pr length checker to make sure.I have .660 lift springs and everything looked great on my ptv clearance.

pacesetter long tubes with pacesetter y pipe with qtp cutout cut off at intermediate pipe got rid of the crappy sounding flowmaster.
