Another learning curve for sure. Tried a few things to find what it likes and dislikes. I first added more pump gas to the tank diluting out the 2 gallons on 110 I added last weekend at MidMichiganMotorPlex, installed new champion race plugs c63cx(7 heat range) and removed my electric fans and replace with a 17" aluminum flex fan. Off the trailer was the best pass with a 10.666@127.30 vs the best pass last weekend of 10.401@129.75. 2nd pass I had the air bell removed just to see if it would again hurt it with nothing on top on the carb and it did. 10.669@126.19, 1mph loss. 3rd pass I switched the HS air bleed from 28 to a 30 to see if it would help on the bottom and it did not, in fact it leaned it out way too much on the top with 13.9afr thru traps and ran 10.715@126.05. 4th and last pass, put the 28's back in, put the air bell back on and removed the 1" wilsons tapered spacer. It ran a 10.711@126.47 with much cooler air. It should of picked up more than that IMO, so the looks like the spacer stays on. I should have put a bigger jet in the rear, maybe 2 sizes, because it was running 13+afr's every pass. I think the flex fan cost about a 10th or 2 and 2 or 3mph. Timing was left at 36* on every pass. I ran 1 brand new plug 1 time down the track. I will cut it open and post a pic. Only way this cars going any quicker is with some hard parts changing, like 440-1 heads and a nice Roller. Not impressed with these Victors.
Here's a pass down the track.

Good Video, I think it could use more converter. You are still legging out 1st gear for 2000 more RPM after the flash. I am not a big block guy but that seems like a lot to me.

Why did you switch the fans? Your runs you made awhile back I think you said it ran 129MPH or so but 60d in the high 1.4s. I would look on the short end of the track for improvement.

Thanks for the video.You tested a lot and got a lot of info so good job!

Yeah, think so. Lenny must have tightened it up. I did tell him street/strip. It used to stall/flash to 5400 behind my 408 SB. It now stall/flashes to 5100 behine the BB.

Yes and I know what works best for it as is. It is a street car, so fairly happy with it anyway. Here's a pic on a single pass plug.

I switched the fans because I could not get the electric fans to cool at road speed. Ran 218-220* most of the time. If I stopped or slowed, temp would pull down to 200-210. Flex fan cools much better ,205 max, but it does cost a few hp.

No black specs,cool.

Yeah, no black specs. That run was with Dom's original tune. If you watch the AFR's in the vid it was running 13.9 thru the traps. A tad lean with the 30 HSB.

I couldn't see the a/f dial clear and was looking at the color if it changed.
I can read it going full screan.TY!

No ET national at Milan runs a pro tree. Got caught sleeping a couple times.

I have read on other mopar sites guys using these victors disappointed as I unless they have 13:1 or more compression. Not many make over 700hp with the victor head.

IMO, that 63 Champion is a bit cold for that CR on pump gas. You can get that in a 65. That's only 1 range hotter. Without seeing the shell it's hard to say how much hotter you should go, but I'm going to say that 63 is too cold.

I'm not sure, but I was under the understanding the c63cx was the hottest in that style.

Been thinking again lately how much if any the 1.6/1.5 rocker combo is hurting me with the cam lobe spec .403/.410? Most think its not an issue.

Yeah, I had to look it up. The C63CX is the hottest in that style. If you can find them, you can get a C63 which is one range hotter, but it's a fine wire plug with the standard ground wire. The C65YC is the same heat range as the C63 and is one range hotter than that C63CX you are using. So the C63 and the C65YC are the same heat range, with different tip styles. BTW, the C65YC is an extended tip, which IMO is better for pump gas stuff.

I used to remember this stuff off the top of my head. Tonight I had to get the book out! Sucks getting old.

Ok, good to know as I run an extended tip plug on the street. Currently using a Autolite 53. What part of the plug are you reading for heat range? I thought that plug looked kind of on the hot side looking at the ground strap. I understand the getting old part real well.

what kind of electric fan setup did you have on ? OEM style or aftermarket ?

Dave, don't take this as a dig at you or your car, but am I the only one who feels like this combo should be faster than it is?

For comparison, my 3700 lb cuda w/ a stock stroke 440, unported Indy SRs, old Team G intake w/ a 1050 dominator, mid 260s at fifty solid roller, and 14:1 compression went 10.40 at 129.1 mph. 5k stall 727 w/ 4.10s and 28" tires. The only thing my combo had better than yours is higher compression.

If there isn't something up w/ the heads, it might need a lot looser converter to get it moving? Have you had it on a dyno?

Kinda what i thought. Figured on relatively easy 9 sec time slips
