Thats very cool stuff Im gonna have to look into that.....It would bend before it would snap. Add some rear sopports and that thing is good and anchored.

 

Do you have the 6.5 power valve still? That probably is a little high.

 

Congrats Scouder. Sounds like she's all there. It must be making a lot more power than mine. Mine will not spin them for 48ft! And my tires are smaller.

Of course, I'm sitting 500 lbs of gas just ahead of the axle :-)


Have fun, but watch out or OEI (operator equipment inversion, had to correct a few recent misinterpretations).

 

It's got the 6.5. Which would probably be OK at sea level, but up here on the hill I'm sure it's opening too soon. I'll have to get a vacuum gauge on this thing so I can tell what valve to get.

Another interesting note. When I first got the cam back in, and fired it up, I was messing with the timing just by ear. I thought I could just advance it until it kicked back against the starter, then back it up a little to get it close. It finally started kicking back with the engine hot, so I backed it up and left it. The problem was that when it got to around 3000rpm it would get real ratty on me, and wouldn't gain rpm anymore. So I put in a blue spring to slow the advance down, and put in the 18 degree bumbpstop. Didn't help so I figured I would just find the problem during my test runs. Yesterday, before I took it for it's maiden voyage I put a timing light on it and found it was set at almost 36 degrees initial! It was starting fine! I pulled it back to 18 degrees and did my runs just fine. Next set of runs I'm putting the light silver springs in, and setting the initial to 24 degrees. This will give me 42 total. We will see soon. Just interesting to have it that far ahead with no starting problems.

That is awesome scoot, cant wait to see it run on the video, and greg hows the 446 runnin now does it feel strong, and I must have missed the 500lbs of gas thing.

 

I took the ol' girl out for another stretch of the legs tonite. I advanced the timing to 24 degrees initial, put in the lighter springs, and left the 18 degree bumpstop in. After warming her up I did another roll on from 2000 rpm. There was a very slight hesitation since I haven't tuned the carb yet, but she dug hard to about 4000 then broke the tires loose. It went ratty just as I let off the throttle and I was concerned because it should have been smooth. As it turns out it was the rev limiter at 6500. The next run I watched it spike the rpm and sure enough it went from 4000 to 6500 in a blink. I think I'm gonna back the timing to 20-22 degrees and leave it there for now and start working on the carb to clean up my transitions. I'm impressed though how fast it takes those big heavy tires loose, especially when you consider that with my 38.5" tires and a 4.11 my effective gear ratio is the same as someone with a 30" tire and 3.20 gears.

Scouder, refresh my memory, what heads are you running on that?

 

Scoot...Seems like eveytime you post a run..I seem to see it in my minds eye...awesome!! and Kurt he's running KC Stage III Heads on that beast!

 

In addition to what I posted on last nights run, I thought I would make and initial assessment of the engine. It is still too early to say for sure how She is going to be, but I am starting to get a feel for it, and I thought it might be useful to some of you guys who are building some pretty hot engines to have a baseline for comparison. I know I love it when somebody posts their build list, then describes the engines behavior so I can form some opinions. I will post the build sheet at the bottom.

The engine idles fast and rough. I would guess I'm gonna end up with an idle in the 900 range, though I have it set at 1100 right now. Off idle it still makes gobs of torque even with the KCIII's, Victor, and big cam. I would say it is more than any FE I have had in the past. It starts to really dig at around 3000-3500. That is the stage that you can tell you are putting some serious power to the ground. At 4000 it hits again with a vengence. I am assuming that this is where everything starts to work together. From 4000-6500 it is spinning to tires for me, so all I can say is it gets there in a hell of a hurry. It is obvious that this engine has big ports and big cam. When it gets up around that 4000 range it is in it's element. My feeling when I hit the rev limiter was that the engine was no where close to done. In fact it was so smooth that I was surprised I was at 6500 already. I am thinking that since I want to keep it limited to 6500 that I may entertain something like the 348801 crane in the future just to compare.

Here's the build list for anybody interested:

LAE Kryptonite 4.25 billet crank
Oliver 6.535 BBC Rods
Arias forged 12:1 pistons
KC Stage III heads
Victor

Erson Rockers
Melling M57 HV oil pump
Canton T pan with windage tray
2 1/8 fenderwell exit headers with 4" collector
CSI electric water pump
BG 220gph electric pump to Aeromotive bypass regulator
-10an lines from tank to reg and back, -6an to each floatbowl

Are you running on 93 Octane pump gas?

 

man you have to be pushing like over 650 hp.....Thats my rough estimate.

 

My initial test runs were done on 110. I am going to come down to a 50/50 mix of 110 and 91 for the next set of tests, then finally the big test, straight 91. We don't get 93 up on the hill. Apparently the oil companies know we don't need as much octane up here.

-Scouder

 

My sea level HP should be at least that. Maybe more. That is if I can tune it sufficiently to let the HP out!

-Scouder

 

do you overheat at stoplights and stuff with that much power?

 

I haven't seen any tendency to overheat. With the aluminum block, heads and radiator it seems to be just the opposite. It takes the engine quite a while to come up to temp. I'll know more as I get more miles on it and start to make longer trips from the house.
