I just wanted to know the difference between power ranging as far as from a LT-4 hotcam vs LT-1 LE1 Heads? Just wanna know the pros and cons to both. I am on a budget as well. Thank you for your help.

The LT4 hotcam is an ok cam if you're not really looking for big power...although there are much worse cams. Ramps are a little lazy. The CC503 cam is probably the best cam for a street car, easy to tune since a bunch of people run them and tuners have been tuning them for years. My old man has a 94 Firehawk with LE1 heads and a CC503 and it runs hard. He's got all the supporting mods too though.

There is probably 15-20 hp difference between the two cams above...Lloyds version makes about 10-12 hp more than a CC503 and doesnt cost much more. AI also has some excellent grinds but they do cost a little more.

What's your budget and what mods do you currently have?

Right. LT4 hotcam setups when properly done on a stock block in the low 12's to high 11's due to their "lazy lobes." These ignorant parroted statements are always comical.

Only mods done to my car so far are a K&N Filter, Muffler delete. I plan on having a wet shot of nitrous as well. My budget for the most part is 5K

Lol the lobes are lazy no matter what you want them to be dude. 12's doesn't mean much anymore.

And why would you choose a hotcam when for $40 more you can have a superior grind in the CC503?

Have you ever posted without insulting people? Why do you choose to live your life like that?

Your asking about the difference in power between a hotcam with stock heads vs LE1 heads with a stock cam? The stock cam is the bigger limiting factor than the stock heads, doing heads on the stock cam will yield close to nothing, but doing a cam on stock heads can give you up to 70rwhp (hotcam closer to 30). I think you need to slow down and do a lot of research before you break out your wallet and regret a purchase.

If that's the case then the LT1 doesn't mean much anymore. I am not sure how long you've been around LT1's, but the average setup for a heads/cam/stock block/supporting mods setup, if set up properly is in the ballpark of mid 11's to low 12's. There are a handful here and there that are in the low 11's, and some with the right amount of weight reduction are in the 10's. That's just the way it's been since the 90's to now. What I said is not a direct slam at you. This "lazy lobe" bullshit has been around awhile, and seems to be repeated more by fans of LE. The same has been said about the CC306 when that cam was putting cars in the mid to low 11's on the stock block almost 20 years ago. I don't know what you know about the LT4 hotcam, but it's a cam that will pass a smog test, so going low 12's/high 11's and dynoing between 370 to 390rwhp with that kind of cam (and a good pair of ported heads/supp. mods) is pretty impressive for a LT1. Honestly I haven't seen a lot of 503 setups that are not doing all that much better?

I did this very thing with LPE ported heads on the stock block. Ran it at Texas Motorplex many times and stock the car went 13.9@100mph. With LPE ported heads/intake, 1.6 rockers and Edelbrock shorties going into the stock y-pipe with cats still in place the car went 13.2 @ 106. The car dynoed 282/300 stock. With heads it was at 310/310. Power and torque curve had exact characteristics of stock, only higher. I can't believe for a second the 6mph improvement through the traps was caused by crap Edelbrock shorty headers backed into the stock cats and 1.6 rockers. Problem is there isn't a whole lot of data to back this up since it's cheaper to do a cam, therefore most everyone who started modding these cars would do a cam first.

13.2 at 106 310/310 is still what hp a car with long tubes would put down on stock heads and cam but less torque. I'd be curious what you would have done with the shortys and rockers and without the heads, I bet it would be close.

With the cats and stock y-pipe? Not a chance. It was widely known soon after that those shorties were useless. The collectors were the same diameter as stock. It was a gadget, but back then that's all that was available for OBDII. With just rockers/supporting mods it has been well documented it's good for maybe a .10th and perhaps 1mph. I am not sure if that is with or without cats/headers/stock exhaust/etc. Remember, I was running the stock cats and y-pipe with those junk headers. What I wonder is how well the car would have done with a good set of headers and ORY. When I did the cam install (LPE 211/219) I ran 12.5 @ 110. Once Hooker LT's became available I put those on along with a shitty non-mandrel bent y-pipe that skeeter welded up for me and ran a 12.2 @ 114. Then put 3.73 gears in to replace the 4.10's and ran 12.0 @ 115.

LE says to go with a 227/235 .565/.579 110 LSAcam.... it gives tons of mid range power and raises the red line to 6300. This will provide a choppy idle also.

With this, you'd need RRs, pushrods, a tune, and probably a chain, etc.

How does the LT4 hot cam stand up to this?

Someone here is trolling hard....

That cam is more aggressive than a LT4 therefore, in theory, it should have a stronger output. The hotcam is a very close profile to one of the cams suggested with the le1 heads.
Typical response. Whenever there's a counterpoint the butt hurt claim it's trolling.

Do you have the atmospheric conditions for your radical claims? Did you use A-B-A testing? Or is it a one and done?

SS RRR is right on the money with LT1 knowledge.

IMO, You really don't need a giant cam to go fast. I mild cam will do better on a street set-up because the power is more in the mid range where your rpm is most of the time anyways. Your car is in the 3500-6000 rpm range most of the time when getting on the gas so if it makes 500 hp at 6400 whoop de due because you are only at that rpm for a quick moment before you shift. into the next gear.

Lazy lobes, to me mean stuff from the sixtys maybe early 70s

You can still get a little more aggressive with great results and longevity of valvetrain. Ive done the real aggressive ramp thing and all it did was wear out the valvetrain prematurely..all of it. Some guys like them to each their own. Not worth a few lbs of torque and a touch of vacuum;I could never feel the performance gain.

No, sorry. I do not have a data sheet. Either that or my dog ate it. I don't quite remember. The runs done were before calculating DA was cool. All runs mentioned were done on opening days during the same month where weather conditions were similar. The only constant is the dyno used. My "A-B-A testing" is I ran the car stock, then put mods on it and it seemed to go a little faster. LOL @ radical claims. Either try or troll harder.

The CC306 and hotcam grinds have been around a long time, before the GenII LT1 was around. All I am trying to say is comparable cams to both the 306 and hotcam aren't doing anything any more astounding than what was done years prior.

Good luck bullshitting your car faster.

Oh c'mon. You can either cry, try or troll better than that!
