Matt, I didn't come into this thread to **** on one of your sales. Let me ask you this???? How can you recomend a camshaft without knowing what the total setup is on a given engine? I simply stated that the op would be better off with a custom grind cam for HIS specific set up. Lets try not to **** in this thread anymore ok... If you would like to discuss further feel free to PM me.

Oh excuse me Jon did. Texas speed sales posts all look the same.

He didn't "recommend" it either, he was simply answering questions that others had posted about that cam in a 383ci engine. 3 people posted about the Magic Stick before John did.

I was one of them that posted that im running a ms4 cam on my 383 and i love it! My car runs like a champ so you are a little off to say that shelf cams suck because its proven in my situation by the way my cr is 11:1

think my compression ratio was 11.2 or 11.3. could i have made more power with a custom grind? yes. would i swap out my "shelf" cam for another few ponies? NO.

indeed!! i get your point and yes a custom cam will be more efficient then a shelf cam!! but most of us already had a cam before moving into a stroker and to save some cash some people start swapping parts and sometimes it works but yes that is the way to go if you don't have a cam go custom and don't look back!!

We also have a shelf stock cam that started out as a design for a max-effort N/A 383. It is our sTRoker V.3 247/251 112LSA. You can check out info on it here:

Also, here is an idle clip and dyno pull:

Those videos are from a 383 LS1 topped with TFS 225's at 11.25:1 compression.

Power was 537RWHP, 478 RWTQ

Thanks,

Lets to some simple math shall we? Whats the intake closing point on a MS4??? If this post
https://ls1tech.com/forums/generatio...pressures.html

is correct its 51 degrees ABDC. Now on a 3.625 stroke motor this may be fine and nets about a 8.2ish dynamic compression on a 10.5:1 static.

But on a 4 inch stroke motor. Its about 3-4 degrees too early pushing dynamic above 9.

The OP wanted advice on what to do with HIS motor and my advice to get a custom cam is right the **** on.

A MUCH better choice imo. Something spec for the correct length stroke.

Thanks Shane

You would need all of the data to fill of these slots to determine if a setup will work or not. These can be found on the cam card and measurements from your bottom end.

What I find funny is how a lot of people always treat setups for maximum dyno Hp
After all, are you gonna drive it or just watch videos and rollers?
MS3 cams and such make fun drivers in a 382/3 cid. MS4 has too much intake lobe for sensible street setup.
Let the koolaid flow

yeh i was just after an idea of what guys are running and if what i was looking at was in the ball park for a good/decent 383 cam or if i should bump up to the second cam i mentioned.
Don't want it as a dyno Queen as its to be driven not sit on dynos every second weekend, want a good 383 stroker that can be driven on weekends and have plenty of ***** on the street Anyway
This has really increased in momentum in the last day, Matt at Texas Speed is doing a great job and look forward to the final setup he has in mind and ordering it, Thanks again for all the info and to Matt as well for his help so far.

The problem is that you still don't have a clue about the 383 rotating assembly I am selling the OP. You are still making assumptions.

Thanks, Ben! I will have that email over to you shortly, just a few loose ends to tie up on it

Thank Matt got the email, all sounds good, can't wait to get this kit in my hands and start putting it together 
