383 Cam Choice Okay guys need alil bit of advice. Heres the history of my motor. Its a 383 11:1 compression. Trick Flow 215cc heads with 5 angle valve job. Super Vic Intake with 4150 TB. Need advice on which Cam to use.
First choice 233/276 585/595 107
Second choice 232/242 625/625 108
Or a better Cam if anyone has input?
I have 475 to the wheel right now with 383, Trick Flow heads & Super Vic with a Low Profile Elbow & a 90mm TB. The Cam is 238/242 595/595 112... I wanna make close to 550 to the wheel this time.

Verdad Gallardo Geoff@EPS has this one for the single plane setup. The problem is, once you introduce a 4" stroke, it changes the optimal valve events. The cam specs are 236/248 108 LSA. The cam I mentioned was a custom. If I were to do a 383, I'd actually have Geoff do a 242/246 113+3... but that's with a FAST. You need to bring the intake valve closing point down with a tighter LSA/advanced intake centerline (ICL).
Here is his 236/248 cam: http://www.engpwrsys.com/index.php?a...d&productId=12
For reference, I have his 234/242 111+3 in my 346.

I actually talked to you Martin & you recommender a 237/247 641/632 107.5... Its huge lol kinda wondering if its gonna be alil much for a mostly street car. It already jumps around alot with the 238/242 595/595 112.

Ya the one in it now is monstrous already. So i can just imagine what the even bigger one would be like, that Martin at Tick recommended. You cant take off with out ripping up the pavement already 😆
You also said you wanted it nasty, so I gave you nasty!
If you wanted something that drove exactly like you have right now and would make the most power from 3500-7000rpm possible, I would recommend this cam:
233/243 .635"/.627" 110.5+3
Also, with a low profile elbow or any kind of elbow on a single plane, you're never going to hit 550rwhp. I understand you want to keep the stock cowl and the wipers, but it's going to choke air flow a good bit versus a 4150 TB.
I think you can make 500rwhp with the smaller cam I specified and 450-460rwtq, but 550rwhp is going to take a serious cam to carry the power upstairs and it's going to have 24+ degrees of overlap@.050" lobe lift.

Remember what I told you about overlap and single plane manifolds over the phone. You also said you wanted it nasty, so I gave you nasty!
