wanted to know which heads and cam i should get for an LS1... i want to push as much power out of that car as i can... what should i get, and where should i get it? got any other suggestions? thanks guys

btw, dont have emisions down here in florida, so maybe that'll help me

 

There is no best...

First off you really shouldnt be asking most of the guys here because they will tell you to run a thunder ca to get the most hp..

If you want the most power you can get ... the cam will be so large it wont really be streatable anymore...

you need to be looking at different vendors and doin some research etc...

As far as a head.. Stage 3 LS6 heads from ARE / MTI / GTP is what id say to go with. And maybe a Solid Roller somewhere in the 240 ish duration 600 ish lift on a 108ls

 

what should i look for in a cam?

and thanks for all the other info, i really apriciate it

 

hmm
cam selection is more a trade off than "I pay more to get the best one." They all are pretty much the same price with trade offs.

The longer your durration, the more top end you have and the more power your have generally speaking.
now if your heads cant flow enough at those high RPMs, you can get enough air in there to give the motor the air it needs at 6000-6500rpm. so in effect you now have no top or bottom end. So you definatly CAN go overkill on the cam although this is less of an issue with LS1's.
Also, on a hydrolic roller and daily drive, if your powerband is from 4200rpms to 7200's, your probobly not revving that high to see your power.
Another issue-
more durration means a more choppy idle. How choppy can you handle?
Some cams make more power with less durration. they have steeper ramps getting the valve open faster, higher and longer. These are harsher on the valve train.
With more durration you need a bigger torque converter to propperly match it. Do you really want to drive around on a 3500 stall every day?
Gas milage sucks with big cams too.
you also need good air intake and exhuast to propperly take advantage of a good cam.

what to do?
Call/email/send carrier pigion to a vendor/engine builder.
tell them what you want, they will discuss it with you and help you pick the best cam for your application. Get a nice custom ground cam, not one off the shelf.

I usually suggest combination motorsports. they also have a VERY NICE GP going in the GP section. They also grind their own cams so you can get a good custom ground cam!

good luck!

For the money, there's noone better.

 

No such thing as best. Do some research and look at numbers. Thunder has put some good numbers out as well as GTP. Its all about what you want out of the car. What is your goal per 1/4 or HP or do you plan on nitrous or forced induction? Find a company you feel comfortable with and call them, but make sure you know what your goals are or they won't be able to tell you much.

 

my goal is to make my LS1 run into the 10's w/o nitrus... actually, my goal was to get it into the 9's, but i want to do this N/A, no boost - no juice, and that's gonna be a lot harder to do w/o nitrus... guess i'll end up spraying, but that's if i have to. have a bad experience w/ n2o... guess it was because it wasn't installed right, but still... once you blow an engine, you'll do anything to make sure it doesnt happen again

R.I.P. Dodge Neon Rent-A-Car .... sprayed 100 shot in it all day long, toying w/ that freakin' car... took it to saga bay to race, cuz i thought it would be funny, and in 3rd gear, i blew the motor cuz something wasn't connected right (all the lines were ****** rigged... it was bound to happen - suprised it didn't happen sooner! lol). ehh : oh well, i'll get over it, lol

 

You want to go 9s N/A with the stock bottom-end? Good f'ing luck.

You will need a stroker or a power adder to go 9s with an LS1.


10s aren't exactly easy either but it's definitely possible with a nice H/C combo.




As others have said, there is no best heads or cam. Do some more research on other boards and see what kinda gains people are getting with certain H/C combos and then go from there.

 

lol, did i say i was gonna leave the stock bottom end? noooo....

12 bolt w/ either 3.73's or 4.10's... i think imma go w/ 3.73's

and im going to re-do the whole suspension, and some weight reduction

and if getting into the 9's N/A seems almost impossible to do... then i'll probably end up having to spray in it... i've sprayed a 200 shot in my dad's 67 camaro when it had the 427 in it... then my dad got tired of his friends telling him that his son knows how to drive that car better than he does, so he sold the 427 and put a small block 350 on it that's only pushing like 250 hp, LOL - oh well i have memories in that car... hehe

 

No, you didn't say you were going with the stock short block but you're asking about H/C...

H/C for a stock 346 is a little different than H/C for a 382, 383, 409, 422, 427, whatever...

Well, not so much for the 382 or 383 but if you're planning on 400+ CI then there are bigger (better) cams available that you wouldn't run with the stock bottom-end.


9s are possible N/A, Colonel went 9.8 with an N/A MTI 422...so it's possible but it's not easy or cheap.

 

yeah, i know... lol, but i have the money for it... we'll, not right now, but soon thanks for the help

 

I know of a man running 9's on ported heads, streetable cam, stock tranny wiht converter, stock rear with gears
9.96
200 shot

 

a 200 shot is crazy though... i've only done it a few times... i tried a 275 shot on an LT1 T/A built for that much power, and i almost lost control. 275 shots leave stains in your underwear man, lol... i think i'll stick w/ the max of 200 shot... cuz that was jusssttt enough for me, lol, i could handle myself in it, but anything more than that... lol, but for now, ill go w/ a 100 shot again and work my way up back to 200... i'd be a little to shaky to go back to 200 right now since the incident w/ the neon, lol
