Re: 383

I looked around on Summit and found one that is close to the duration and LSA that he gave me. Is a 113 LSA going to be good enough? That's what the COMP Cams guy gave me as a LSA. Here's the specs of the one he gave me...

Grind # CS-3016S/30375HR113
230/236 @ 50
576/571 Lift
113 LSA

It has a 2000-6000 RPM Range and he also said that I needed to specify "small base circle +4" when I ordered it. What is that?? I'm so confused. The part number he gave me for the cam is 08-000-8. Summit has one that is very close to what he gave me but has a part number of CCA08-467-8.

They also seemed a little rude...

that cam with a 112 lsa would be great for a 383. the small base circle comes into play when you put in the stroker kit. alot of stroker kits already come clearanced for regular cams, the ones that don't, require a small base circle cam. i'd get ahold of CNC and find out from them which kind you will need to run their 383 setup that you plan to buy. you said you were keeping the LTR setup correct? that cam is also a little more towards the hsr intake. you'd want something more like 1k-5.5k for a powerband.

Re: 383

I don't have LTRs...I have the SLP Runners and an Edelbrock baseplate. I'll give them a call on Monday. I'm really debating on letting the garage chose the cam instead since they'll be the ones building the motor and tuning.

Re: 383

I wouldnt if it were me. I would go by what Comp Cams recommended. That kit you are gettin should have the rod bolts already cleared so that you dont have to get a sm base circle cam. If you cant get aholt of Comp lmk, ok, and give me all of your specs and I will see what I can do ok.

slp runners and edel base are still the LTR setup, they just flow better. they definitely won't flow to 6k rpm though. i would choose the cam if i were you, i wouldn't leave that up to any garage. that cam that CC recommended on a 112 lsa would be a great cam. i'd look for something in the 1k-5k range though. or if you want that motor to really scream, sell those runners and base and throw on an hsr with the cam CC said to use. local buddy of mine just dyno'd his 383 hsr motor, made 378/426 to the tires. it's planted in an 87 GTA.

Re: 383

Sorry Munson, but I'm going to be keeping the setup I have for now. I dropped about $1200 on it and I'm already up to around $2500 in parts for the 383. If I hadn't just put that stuff on before my oil pump failed then I'd look at the upgrade to another setup, but I can't justify spending another large sum of money for a new intake, runners, etc to replace what I just bought.

Why would you not let the garage pick the cam? If it was a regular fly-by night garage then I could understand, but if I'm taking the car to a performance shop that has a focus on F-Bodies I don't see why not. As for the cam reccommended by CC, how do I get one that runs on a 112 LSA? Even through Summit the similar cam was set on a 113 LSA.

Re: 383

That shop may be familiar with fbodies ,but its probably LT1's and LS1's. I would still go with the CC one, and then get a custom chip burnt.

the setup you want to use is up to you man, i'm just here to put in some info. but basically what i was saying is the money you'd get from selling those aftermarket intake parts would pay for the hsr, you wouldn't be spending any extra money really. but i'm sure with the LTR setup and a 383, you'll never stop smiling, the torque will be great.

i wouldn't trust anything up to a shop when it's something that important. take your time and research and you'll find the perfect cam for your engine, that shop would just pick something close and throw it in.

Re: 383

Also, the LT4 Hotcam and the HSR would work great together as well and you can find those cams CHEAP!
I agree with Munson 100%!! TAKE YOUR TIME!!! DONT be in a rush! I have seen more projects go south b/c the one doin it got in a rush. Remember, Rome wasnt built in a day,lol. As far as the HSR I agree, you will be ALOT happier with it as well, and the TPI stuff, you can sell to get one.
You put that with a 2500+stall and that Hotcam, HSR and a set of 3.73' s and HOLD ON!!! You will look like Jack Nicholson when he played the Joker in the first Batman, they will never be aboe to take that grin off of your face.
