$300 for a set of fast36 which are actually 42lb isnt alot at all.

He seems to be from overseas

Youll need ALOT more intake duration to make 440. Id say about 233-235 intake and 241-244 exhaust would do it. but on stock port 243s....not sure there. top end hp on an ls1 means no bottom end also and very hard to drive down low and cruise also.

Darth makes 520 rwhp with his ls1, revs to 7300+ and it's his daily. Seems to have no issues with bottom end power

Everyone's idea of streetable is different.
Hell look at that street outlaws show, they all believe those are street cars.

He also has a top of the line set of heads. (For the application)

So are many of the other parts.

If the op is overseas, then the main issue is being dead on. Shipping alone is not only a pita but costly.
I would Install the fast and other components first then tune and see what is left.

*Street raced cars :p

But yeah if you have really good heads you can make more power with a milder cam

If you can, order the FAST 36s... they have excellent data and are genuine Bosch injectors and can be had around $300...

If the heads are okay, your existing cam would work. Otherwise, I'd do something in the 226-228 intake range, and add about 12 degrees exhaust.

So, something like 226/238 114+3 would be streetable (with lower overlap) and make good power (with the earlier exhaust valve opening). It's probably the limit of what I'd call perfectly streetable with 4 degrees of overlap. But if Comp Cams does it, I'd do an LSG intake and LXL or XE exhaust lobe. If Cam Motion does it, do the .621/.604 lift lobes.

A 228/240 113+3 would make a little more juice and drive a little worse. But would still drive pretty ok. Same lobe combo.

Both would be more noticeable than the existing BTR cam.

Jake your name getting used in vain a lot lately

Bspeck82

Why so much exhaust duration? Would keeping the valve closed longer not suit a street combo better? Obviously it won't carry as far but it would make more torque in the usable rpm range.

He wants 440 thats the issue. Squeeze 45hp out of 2 or 3 degrees of intake more exhaust duration...i dont see it honestly.
Put the fast on it tune it and see what you need.
Dont just buy a cam and throw it in in hopes itll work. Put the part you have on and see what happens. without cnc heads youll need a bit more duration than that.

In comparison, the hawks kit has 59cc cnc 5.3 heads, fast102/102 and a 230/238 and inj and they say it makes 450 rwhp+. That's alot more cr and more duration than a 226 plus a fast 102 and 102mm maf and cnc port.

Because exhaust duration makes power. You don't lose much torque. But it carries a lot better. This idea of single pattern or 4 degree split isn't how you make your car fast. SBCs, 5.0s, and BBC with similar heads are not cammed like that. Of course, the intake plays a part in that more than the heads, but still, engine physics didn't change. More and more LS guys are going back to the older school for making power. Geoff @ EPS was one of the first to put long exhaust durations back into his shelf grinds.

And you don't need a lot more than 230 duration intake in an LS1. Bigger is not better. The FAST will help. But it still won't hit 440. I suspect the heads, though worked, are not TEA or AI level.

For example, my 227/244 cam carries better than most bigger cams and drives better. It's making more power than the 234/242 111 I had in there...

Some people will argue til their last word they are. Im sure there were a few threads about that on here plus the whole "what is a street car" threads etc

some people dont notice what others will and before there was a tuner around every corner some shops just told "big cam guys" that is how their car will drive and they should get used to it.

I dont want to turn this in to that type of thread, but like i said, with a customer overseas, youd better be right on or have a pissed off customer half a world away.

big hammer

What's "streetable" is very subjective and varies greatly by region. Some places have emission testing, others don't. Some don't mind a little bucking from a large cam while another might get pissed right off by it, etc

Street out laws are street raced cars that they could technically take through a drive through, if they wanted to.

i liked to stay streetbale car !
What do you think about this specs custam cam
231/241 115 !
The overlap 6 !!
