Im doing the GM ls6 ported heads and hot cam swap(not sure on if i will use this cam, suggestions?) on a stock ls1 6 speed-----(s10),I dont think I will have the time to have the headers made,but,using stock camaro manifolds or 1 1/2 tube headers,what do you think the hp/tq would be?I know they did this swap on a stock ls1 but with 1 3/4 headers and it made 510hp.. . . . . .it will be a everyday driver with ac

 

if you are not going to go with headers I would get the CheatR cam and if you are going to get headers I would do a 224/228 cam or a 224/224 cam, thunder racing or Texas-speed.

 

Nothing wrong with the hotcam! Just throw on a set of 1.8's RR's and should give you
.556 lift. A good set of springs like patriot golds, and never have to worry about spring life and you can have your AC on full blast all the time! Just my .02 cents
Goodluck on finding your HP and TQ numbers!

 

You won't be hitting 510 HP with a hot cam an LS6 heads, maybe 380 RWHP which is about 430 HP at the flywheel with 12% drivetrain loss. I would go with a bigger cam.

 

I have those heads in 65cc. I've had a GT2-3, 228/232, and now a 220/224 cam with those heads.

The GT2-3 did 393/380 on a dynojet
The 228/232 did 427/388 on a dynojet
The 220/224 did 405/385 on a Mustang.

The first two had a Corsa Touring cat back and the last has the stock cat back. The usual mods were for all: headers/cats, pulley, CAI, ported TB(except 1st). The last two also had Yella Terra rockers. And finally, the last one had an LS7 clutch compared to the stock LS6 clutch of the first two.

And F-Body would put out a little higher numbers.

 

I made a boo boo..
Erased..

 

The 228 wasn't Ed's. It was an XER gring. I'm sure I would have kept the 228 if it was Ed's.

Seems all his stuff works

 

Now were getting somewhere...
Oops on the Junk reference for good ole EDC...

EDC kicked that XER Cams ***,I am really suprized at that outcome
Very impressive

 

Well, I have the book that says other wise with a dyno sheet.The heads are cnc ported in case you didnt know......these heads,hot cam,ls6 intake made 510 hp on a stock bottom end ls1 motor on a dyno with 1 3/4 LT's,yep,sure did..but anyway,i have everything but the cam,And the reason I was using "stock GM parts" is because i have no idea how to tune these motors.I would like to use a cam witha little rumpity rump,but dont have too...just looking for some advice.

 

I have the hotcam. Combined with 1 3/4 LTS and a cutout, it actually has a lot of lump for being a small cam. I don't mind the cam, but I do wish I would have put a bigger one and better valvesprings in when I was rippin into 'er. I have the stock LS1 heads, mildly ported, ls6 valvesprings. I made 366/350.

 

You should see if that book is gonna give you the 100hp that you come up short if you follow it... just really hate the hot cam.

 

Umm must be engine dyno for the 510.That sounds more believable.

 

yea engine dyno.....but Frost,thats what super chevy did it their book.But I dont know if im going to use the hot cam or not,just looking for other peoples advice.thanks everyone..The thing with mine thats going to hurt me is Im using the stock manifolds or only 1 1/2 tube headers.So I know Ill lose HP..

 

Should be lots of good cams used in the classified. Use an ls6 intake manifold.Doubt the headers would cost you that much hp.Get a underdrive also maybe. S10 is light so thing should fly anyway.Bet you could hit 380 rwhp maybe 400rwhp.

 

Didn't mean too sound harsh, it's just that if you are going to take the time and money to do a cam swap, there are tons and tons that will yield better results than the hotcam.

 

:agree: Hot cam sounds better than it works, a thunder racing 224/224 .563 ^113 would triumph it and sound the same
I ran a GM asa cam for a while with the GM ASA heads. great setup! it only dyno'd about 420/396 but man it had awesome mid range. It was runnig 11.2-11.4 while the rest of the 440-450 rwhp cars were fighting for 11.5

Regardless of the cam, your going to cap yourself without headers. Heads & cam will help move air in the motor, you need to allow the air a way out.

 

yea, I have a 10 second s10 already,but only gets 5 mpg of race gas,not a good street thing..ha.....I figure i will do the lsx swap and get about the same HP with triple or better the gas mileage....on the headers ,unless i have a custom set made,im stuck with 1 1/2 tubes or the manifolds.

 

510HP was at the Flywheels with no accessories. I have the book also.. old chevy high performance.

 

If your using the Speed World GT LS6 heads, 88958622
with the 60.9cc chamber and the GM Grand Am Cup Cam 239/251 570/570 106 spinning to 7200 rpms AND light wt rotating assembly ( not stock bottom end) Then YES 510-to 540 BHP is very possible.
The Speed World GT C5 corvettes used these

No it will not be a streetable head cam combo and is a bitch to tune

 

I have the "Speed world GT LS6 heads" and with the VRX3 cam I put down 410/393. My car also sucks compared to most GTOs in the power department for some reason :-\
