BTW - Hooker makes a BlackHeart Shorty Header that's is CARB approved for LS1 4th Gen's that has 1 3/4 inch primary which is bigger than the JBA 1 5/8 shorty header primary.

Plug changes look fun with those.... well that one side anyways, can’t see those making much power over factory manifolds though

Why so against doing heads?

You were all for doing a cam and wanted to retain driveability and pass smog etc, heads will get you there but a cam won't. But you're avoiding heads like the plague. They're not any harder than a cam swap, honestly I'd rather do heads than a cam swap and I've done both. The heads will do everything you wanted and a cam won't..

If I was going the legal route I'd plan on going with this.

With CARB shorties, ported stock heads and it should net well over 400+ hp daily street power.

I was exploring my options and it seems that heads are one of the most efficient ways of getting where I wanna be. I was under the assumption that a cam with the necessary supporting mods would be enough, but it is now clear to me that there is more to it than just throwing in a cam and calling it a day.

I daily mine with a Torquer V2. Streetability is great and it's tons of fun. It made 413 whp, however, every dyno reads differently, so numbers aren't everything by any means. I have a feeling it wouldn't pass smog though.

Very true on dynos. So what kinda times did it run?

Because the object is really to get better acceleration......not which cam, heads or how much it dyno'd.

Thumbs up 400 hp!

I only want 400 also. What do you think, will i come close with lq9 with a truck cam, 216/220-550 lsa114. Gonna mill my 317`s 30 k and put a tbss on em. All this for fun and an education, lol.

Oh okay, gotcha.

Exactly


OP, if you want to go faster, there's a lot of ways to do it. Many of which won't cause you to fail inspections either. Unfortunately the cam is going to be the worst option you have here. Hio has made a lot more power than I have with a stock long block car, but I used to bust cammed car in my full weight stock long block (stock heads, cam, etc) car. It's all about making everything work to it's potential through a well put together/matching simple setup.

I found a bunch of results from a google search...

The fast is a dead giveaway for visual but without if your not gonna have that all you gotta do is just keep the stock exhaust and swap it back on when you have to smog and do a lil retune. (that is if you cant find someone to "help" you out). Thats all you gotta worry about since the heads look stock, and youll never see the pulley.
LS6 heads would not be an option if you want to keep it 100% legal, but those AI ported 241 heads with welded chambers mentioned above, or AFR 210 heads would get you to your goal.​​​​​

Passing the sniffer test was required so cam size was limited. This was before ls1 edit software was popular and the pcm tuning wasn't as refined as today. There weren't any electric water pumps or affordable roller rockers either. He was stuck with the stainless steel exhaust manifolds which don't flow as well generally as the cast iron ones from 2000 up.​​​​

Ray decided he wanted more power, but he didn't want to spend too much and he had to keep the factory exhaust manifolds.
With help from geoff from engine power systems, we formulated a budget sleeper approach. We would add bone stock 243 heads (unported and unmilled), add comp 918 beehive springs, swap the ls1 intake for an ls6 intake and make a custom cam using engine power systems custom eps lobes. These lobes have been making incredible power with beehive springs. The way this motor revs is a thing of beauty. Cam specs are 218/230 .595"/.600" 115lsa +4 advance. The new power was 403rwhp/392rwtq. A gain of 71rwhp and 45 rwtq.
Again, sub ported 241's or AFR's for the 243 heads...

The size of the intake valve is not relative and that issue is tune related.

-6* overlap, should pass with no issues.

Because i wanted a cam that worked with stock exhaust manifolds as opposed to headers it is relatively mild (218/230, 600 lift) and is on eps lobes. It was originally installed with stock heads and stock rockers with the usual supporting mods (push rods, timing chain, dual valve springs). Later i went to trick flow heads with different push rods, jesel rockers and a fast 102 intake (which is known to amplify valvertrain noise). Neither of these setups exhibit any significant valvertrain noise. So i have no reason to conclude that cams with eps lobes are inherently noisy. They are known for being easy on other valve train components.
In any event patrickg specs cams on other lobes and can be reached here:

This last poster was from Texas, which is why he would not know if his setup passed smog in CA. It's just another example of a well refined setup with stock exhaust that makes the numbers you are looking for.

Good luck with your build!

Go even further... one of the main benefits of a cam is extending rpm range. Lots of cars in here and elsewhere cammed but not revved. Counter-productive.

The absolute best bang for the buck that can be finished up in a weekend with no chance of an emmissions fiasco is 4.11 gears and a 150 shot.

you would never want 4.11 and a 150 shot on these cars imo.....especially w/o extending the rpm range or running a 28" tire.

now maybe a 150 shot and 3.73/3.90 would work. A 150shot would run over top 4.10s way easy.

You'll want the 4.11's for the extra acceleration on the street all the time. You can easily turn down the 150 shot with a jet change and plug swap if need be.
