Some of us have been delayed. Trying to get the car running tip top and getting numbers before we slap the 236 in, you know it get's tuff when ya work all the time . Should be getting numbers soon though...

 

Damn I wanna see #'s on this cam-might be in my future mods list.Let us know how it turns out.

 

My Cam is in the car now,just need to check P/V and let her rip.Tha Cam card was around 237/231 .597/.580 lift on 111 and 108 centerline.
I wonder how long my 918's will last

 

Now that is a huge reverse split..

 

It is, and I LIKE it! I believe the exhaust side tends to not see much gain after 230 degrees. That should be an awesome cam.

 

Colonel do you have any proof to your tends to not see much gain after 230 degrees statement? You could start a independent thread and explain if you like to not steal this current topic.

 

I just checked P/V clearance and have plenty.This car will be running tomorrow

 

Slowhawk, are your heads milled any? How will this fit with 5.7 heads milled .025"?

Anyone trying this cam with an A4? I wonder how extreme it would be.

 

I used to run a 320/320 in a '67 Firebird, but that was advertized duration, not at 0.050. That's still pretty big though; probably around 270* @50 thou.

 

HOLY **** !!!!!!!!
there are only 360 degrees on the whole shaft!!!
why bother closing the valves at all???

 

My Heads are LS6's with bigger valves milled .030.The intakes already had valve reliefs cut.My exhaust ended up with .150 Clearence and intake was over .175 at the tightest spot.

 

Slowhawk is it running or what? details details!

 

"Colonel do you have any proof to your tends to not see much gain after 230 degrees statement?"

I believe this to hold some merit based on what MTI has seen in their testing. However, I do not yet have a clear understanding as to why this seems to be so.

 

Actually, there are 720 degrees because cam duration is measured in crankshaft angle, not cam angle. Note that the crank must make two complete rotations to turn the cam over once. If you were to degree that 320 advertised directly on a lathe, you would actually measure 160* @ 3 thou cam shaft angle. Does that make sense?

 

Very interested.... track and dyno numbers.......

 

makes perfect sence thanks...

 

I was just wondering.. I have tested 3 cams with my current heads and my traditional split produced the highest horsepower #'s, but I did lose a little tq. I still need to get some REAL tuning done and get rid of my MAC's for some actual longtubes.. Now granite the cams I tried were from different spectrums.. Let me break it down.

cutout open cutout closed
232/226 .595/.585 415rwhp 394rwtq 404rwhp/382rwtq
226/226 .585/.585 402rwhp 380rwtq 391rwhp/373rwtq
232/236 .595/.598 421rwhp 390rwtq 410rwhp/380rwtq

Cam 1 lsa 110 zero advance
Cam 2 lsa 114 3 degrees of advance
Cam 3 lsa 114 4 degrees of advance

The funny thing is the 226/226 cam felt faster and idled like stock, but the dyno showed my current heads did not like that cam. We even have a local guy name Jim who dyno'd over 405rwhp with the same 226 cam. I sold it to him. The kicker is his car is a A4 with a huge stall and I think he had 3.73's. Go figure. He does have longtubes though. I lost power everywhere compared to Cam #1 and Cam #3 with the 226 cam. Now I have to take into consideration that my car has not been OFFICIALLY tuned since the T1 cam I had in the car. The only thing Ed Wright did was decrease the timing because I was running some pretty high compression b4 my last engine decided to let go. I only did one pull on Cam #3 because my goal was 420rwhp with Stage I heads. I got it and I was happy. Would I see a huge increase if I decide to stay NA and go Stage II? Who knows.. I am still a little skeptical of some of the #'s I read. Until I see 440rwhp plus on one of my local dynos's from a H/C 346ci LS1/LS6 car.. I will continue reading and smiling.. Am I a little curious about Thunders new cam..? Hell yeah, but I am tired of tearing the car apart..

 

will this cam work with the stock heads and stock pistons?

 

What I'd be curious to see is what would happen with a 238/230. It would have the same total duration as the 232/236. My bet is that it would make better power than the 232/236.
