I have a 383 Lt1 it has 11.8-1 comp. Stock heads that have been ported. and a CC306 cam.Here is the issue, it dyno's what I think is a really low RWHP.I have had it dynoed in different places and they have all been about the same. 368.9 RWHP but here is the wild part 499.6 RWTQ.I know the cam has to be holding me back because there are alot of stock cube cars making more power than me. I should also mention these pull's were made through an unlocked TH350 and on ET street's. I would think this engine should be making at least 400 RWHP.But not to say the car don't haul ***.My best time in the 1/8 was a 7.04@98MPH with a 1.41 60'.That was also with 3.23 gears.So any thought's and suggestions on a great cam grind either off the shelf or custom would be appreciated.BTW on a 150 shot the car made 468.4RWHP and 581.7RWTQ.It basically picked up 100RWHP on a 150 shot.

take your dyno #'s with a grain of salt,,,big stall auto's on slicks never dyno well. Your track times are showing you are making power.

My 246/254 .613/.590 112 12.2:1 396 only dyno's 390whp NA, 510whp on a 150 shot, and 530whp on 200.

But she runs better than the # would lead you to believe.

The 7.04 is that NA or on the jug

if i were you i would just let my track numbers do the talking. there are folks dynoing way more and going down the track way slower. your making the power i am through an auto, i have the same cam in my 383. i have stock heads barely ported and i make 370/370 through a 6 speed so you are not in bad shape. i think if you are looking to get over that 400 mark maybe look into some new heads. who did your heads?

Were your track times n/a or on the spray? If they are n/a with 3.23s your car is making plenty of power regardless of what the dyno says...I only dyno 375rwhp...

Gary Saunders, He is not really known for Lt1/ls1 cars but have always had him do my heads with great results. I may just leave the cam since it runs good and I am about done with my L-92 headed 408. He also ported these heads.

My bad that is an important piece of info. The times are NA.

Ray@Nitrous Outlet

I am more concerened with trck times seeing as I dont race a dyno. Just wondering if I could get some more power to go faster cant seem to break 7.00's NA.

I only made 451 rwhp and a pathetic 366 rwtq if that makes you feel any better

the 6`s will come maybe you just need better air

7.04 @ 98 mph in the 1/8th with your set-up and your not happy? Those have got to be some of the best #s I have ever seen with what you have. You must be a hard guy to please.

Dont get me wrong I am happy with the times. It is just that the car was built back in 2002. I thought there would be something better in the way of a cam to pick the car up a little since that was 6 years ago.

If you are asking whether you can make more power with a different cam, I would have to say yes. The 306 is really kind of a small cam for a 383. People have had good results with it, but I don't think its the best by any means.

Call up a sponsor and get a custom cam designed for your setup if you want the most power.

I have seen alot of post on Joe O's cams. Anyone have any info. about his cam's.

Leave that engine alone, put a 4.11 gear in and some more converter.

What does the car weigh?


That engine is making GOOD power, I have seen cars run VERY well with a CC306, and a GTP6 Cam(almost the same).

you could probably switch cams and pick up a little....but the big thing to me is the 3.23 gear...if you run strictly 1/8 mile I would think you want alot more gear.

I am running 3.73's and a 27" tire...I am barely into 3rd by the 1/8 mile on motor.

4.10's and a 28" might work pretty good for you and still let you run 1/4 mile if needed.

I have recently put 4.10's in the car and hooking the fastest I have got the car in the 1/8 is 7.21 and I lost a few MPH. I think it makes since what I had going for me was big low end TQ.I have 26-11.50 ET streets.

Not sure about the weight. The only weght savings I have are no PS or AC. It has a TH350 and drag lites. But it also has BMR subframe connectors so that adds a little weight too.
