Looking for a cam for 383 lt1
Looking for a cam for 383 lt1 Ok guys I'm asking for Cam recommendations for my 383 build.
Here is what I know. Bottom end is almost done. It has a cast 383 stroker kit in it. and I am told it will be 10 to 1 on the compression 54cc head. I am looking at 2 options for heads. 1 trickflows new fast as cast 190/ 54cc chamber N/A head or to save money stock heads just cleaned up( basically stock). I don't have much money and I will drive this car quit a bit. It has a auto trans built to hold 500hp and a 2200 stall that I will part with for a bigger stall if I need to. I have been looking at XFI 466: (218/224 .570/.565 113lsa) w/ 1.6RR's
This motor needs torque. I don't want to be spinning it more than about 6500. I am looking to get what ever power I can out of it and keep some street manners about it. I will be changing the injectors to 36 to 40lbs, stock plenum, I have long tubes off road Y with no cats, cat back, 52mm bbk tb, and egr delete. let me know what your experiences have been and what has worked.

What is your top end? would this cam be good for aftermarket heads or the stock LT1's? For 1500 bucks I can get a set of trickflows, or for a mear 200 bucks I can just get the stock heads ready to go. I know the trickflows flow better but with a stock plenum is it going to be worth it?

Log onto GM HIGH TECH PERFORMANCE magazine's website and use the Search feature for the LT1 Head Shoot Out. GMHTP recently tested five or so different LT1 heads and a couple made over 500 HP with a XFI 467; which is 230/236@ .050", in a 383 engine.
However, the 466 is a NICE cam too, giving more low end grunt with stock rear end gears, auto trans and would have nicer idle too.
Just my view.

I'd have your stock heads ported and add bigger 2.00/1.56 valves...I used Lingenfelter and E.B. Porting for heads and a nice small custom Joe Overton spec'd 226/234 cam with .568" lift on a 111 lsa...Its a great DD cam...and I'm done by 6400 rpms...My egr and AIR stuff is still hooked up and it may pass emissions if I had that in my county...If you want to stay off the shelf I'd use Lingenfelter for the heads and use their 211/219 .533/.560 112 lsa grind...I ran that set up for years on my 383 with a Vig 3600 and street friendly 3.42s and had a lot of fun...The Vig line of converters are extremely efficient and very street friendly...I take drivability very seriously and I run a Vig 4000 now with 4.10s and would drive it everyday if I had to...
I don't know much about the Trick Flow stuff, but for most of us the stock heads are more than fine for our stuff...

Hum, thanks for the info guys. Yea I took a look at the lloyd Elliott stuff and I can get the LE2's with a cam for about 1600 + shipping. I do like tha fact that the xfi 466 has the low end grunt because thats were I am going to be stop light to stop light stuff. I don't go to the track and I will drive it some as the leases on my truck is up and I am going to getting something just to tow my boat and make trips to homedepot so I will end up driving it a bit. I will look at the Lingenfelter and E.B. Porting for heads as well. I am going to be doing something before the end of the year on the topend but I also have to keep the cost down because I am going to try and buy a salt water canal front home as well while the prices are down so anything I can save will be used tward the home. Thanks for all the help guys let you know what I come up with.
Yea this is me fighting my father tooth and nail because he just does not understand this and other modern motors. I told him to have his engine builder buy a kit that would net me 11 to 1 with a 54 cc head, because I knew I wanted a N/A motor with either a stock reworked head or the after market trickflow N/A head. To be honest with you I am praying that it makes 10 to 1 because his engine builder said it was 9.5 dynamic or static but I can't remember because I was so pissed hearing that it was way below 10.5 to 1. I am still trying to find out what the piston + or - cc is. This is what sucks when I live in Florida and he lives in Georgia. His engine guy is doing the machine work and he is putting it all together for me. It seems I can't even trust family to do what I ask lol. I am waiting to hear back from my father about this now. He is thinking old school that I need to stay below 10 so I don't risk detonation with everyday pump gas but the reverse cooling works to my advantage there so,I don't know. I may end up having to run a small blower on it witch that changes the cam as well so I am pissed but what am I going to do It is already asembled and I don't have the funds to fix it at this point and I will barley have enought to get it on the road as it is.
Talked to LLoyd today and we came up with a setup, It is going to be a set of LE2 heads with a 223/230 565 lift 112 lsa cam. He is a great guy to talk to, and after talking this is what he felt would best suit my needs. I came down on the power expectations as well insted opting for a torque motor rather than HP. I don't ever go to the track and most my fun is just stop light to stop light.

It's good to see you talked to Lloyd about your needs with this build. I'm sure you'll be happy with the driveablity of this combo.
Did you happen to mention your concerns about the compression ratio to Lloyd? I'm just wondering if he suggested cutting the heads a little extra or what head gasket to use?

You cant shave them enough to fix 9.5 to 1, time to buy a blower.
I've dealt with the old school guys plenty of times telling me there wasnt a chance in hell my motor came stock over 10 to 1 compression. Then telling me I needed to get some aluminum heads, then saying I should put a Rock crusher in it....
Lloyd gets my approval for setting you up with what you need to meet your goals.

Well I finally found out that the piston is a -16cc piston so the compression with a standard size gasket is going to be 10.8 to 1 or I can go thin and get 11 to 1. so I am good there now as well.
