Cam for a 388 All Bore
Re: Cam for a 388 All Bore If/when I do my 388, I'm going BIG.....
reason:
the TR 230/224 is becoming a standard size for 346s so a "comporable cam" in a 388 is going to need more durration to run the same (fill the cylinders).....
So I'm planning:
either a 236 or 238 durration on a 110 or 111 LSA if I do hydrolic lifters....
OR...
if I go solid lifter (which I'm really considering), I'll go with something like a 244 or 246 on the same LSA (since solid needs a about 10 degrees more durration than hydrolic).....
this is my daily driver....BUT....realize this is going in an M6 car so I'm not too worried about idle quality and can always just up the idle rpm some if needed....(you didn't say what tranny you have).

Re: Cam for a 388 All Bore Tiny cam here in my 388: 243/250 .610/.612 114 LSA 
Idles great and is perfectly driveable, SVO 30# for my car too, stock 99 ones definitely were not enough.

1) are you running hydrolic or solid lifters on that 243/250 cam?
2) where did you get it?
3) why did you go so much exhaust vs. intake durration?
4) where does the cam peak at with the 114 LSA?

Re: Cam for a 388 All Bore Camaro Guy:
1) It is a hydraulic cam.
2)Andy's Auto Performance (AAP). It's their J2 cam (after me
), they are a sponsor on this site. (626) 447-3707 call and ask for Mark.
3)I don't know for sure, you'd have to call and ask AAP. I have a pretty beefy exhaust setup (1 7/8 headers, dual cutouts), maybe the extra exahust was to take advantage of that.
4) I made peak power just a little shy of 6300 rpms on the dyno.
Hope this helps. ~Tony

More duration helps the lack of high flow #'s. So a higher intake duration than exhaust would make up for an intake setup that didn't flow as well as the exhaust, where as a higher exhaust duration would make up for a more restrictive exhaust vs. the intake. This is for NA only. With FI and nitrous, you need more exhaust flow than with NA.
Velocity- Would you mind sharing what your shortblock cost?
Re: Cam for a 388 All Bore Yeah, again that was a guess. I originally was going to go with a 236/238 .610/.612 111 lsa cam, but I told AAP that I wanted to push the envelope a little further So again, it was AAP's choice for the cam, maybe Mark from AAP will chime in. I paid around $4k for the block, it is an LS6 non-darton sleeved block.

Re: Cam for a 388 All Bore Did you ever get my email I sent you? I would like to get in touch with the shop that did your block to see if I can get the same sleeves you did.

Re: Cam for a 388 All Bore I going to be trying a third cam for my 388 fairly soon, so here is my input:
Any cam you could use on stock displacement, such as 230/224, 229/229 is too small. The displacement will just eat it up.
My first cam was a 232/236 MTI R1. I think you can stick this in an aggressive stock displacement h/c setup...it was too small. Torque was awesome but peak hp was 6k rpm.
Second cam was a 242/242 595 112 lunati. For me, it made about 14 rwhp peak more than the 232/236, at a cost of 7 rwtq peak. However, I lost a lot of torque in the lower rpm band, too much in my opinion to make it worthwhile.
Now I am going to downgrade a bit and go with either a comp XE-R type 236/236 587 (new Z1 cam offered by MTI) or 238/238 585
I am running around 10.8:1 CR and my goals are street and strip -- I want something that is fun to drive and not just all top end.
I am currently using 42# FMS injectors, for whatever reason the 30 lucas ones were not enough, and I was running out of fuel at 5900 rpm, with AF hitting 14 at 7k rpm.

Re: Cam for a 388 All Bore The cam I am running has almost 20 degrees less total duration at .050" of lift than the one Linear Velocity posted specs on. Just goes to show you don't need a huge cam to make incredible power with an all-bore.
Re: Cam for a 388 All Bore good info ezss!! I just have a little 383 stroker, but cam sizing should be very similar.
I think a 230/227 would be too small.
I've gone through 2 aftermarket cams in mine.
224/224 .539 114lsa. made my car sound STOCK but made 448rwhp/439rwtq. kinda cool having an 11 sec sleeper car.
236/232 .602/.575 112lsa made 457rwhp/448rwtq and gave up nothing down low. sounds great too.
when I go SR and get an aftermarkt intake I'm gonna go about 244/244. .600ish lift.
