LS6 243 casting is better than any of the ls1 castings stock and ls6 heads have light weight sodium filled valves

Ok well budget wise this is a save up and get it as i go. But i plan to put this ls1 in my 280zx. Ill put it in now and just swap parts as i go. But mostly topend stuff. Heads, cam, intake, headers ect.

Im also trying to make a hard ground thumper too.

explain "hard ground thumper" please?

Bigmike4098

Loud, deep sound that you can feel in your chest when the car idles.

That is about 95% in the exhaust and 5% in everything else...so if you want a hard thumper look elsewhere besides heads.

Bigmike4098

No i want the heads for power. But if i can make it thump harder by doing something to them then i would like to know.

That would be cam (with tune settings) and headers/exhaust. Yes, heads will make more power matched to the cam, but you don't need heads for sound and power, if I understand your goal correctly.

as far as a certain sound you want thats personal preference.

loud is one thing. you can run straight pipes with TDs and im sure itll be deep and loud as ****.

i run KOOKS with my OE SLP DD with a H/C setup and it works for me.


you might want to listen to different setups to decide whats best for you.

sounds like you could be a happy guy with a cutout..

redtan

Nothing really done to the heads is going to make it thump harder. It's all pretty much in the exhaust.

You can have the most badass heads in the world sound quieter than stock and you can have the stock heads sound like pure hell all with the change of the exhaust.

But I agree, a cutout is what you want at least for the sound.

Bigmike4098

Yeah i need some cutouts. But what are the best heads for a ls1 tho?

HCI2000SS

The best heads are ones like Mast, Trickflow, AFR, etc....certainly not LS6 or LS1 heads lol

Bigmike4098

How much more power can i get with a set of trickflow heads with a big cam?
