I'm doing well, AJ, thanks for asking. Well for an old man who has the snot beat out of him raising Heather, Kyle, and Kevin. Seriously, a day at a time, I am grateful for each day I can be veritical and taking nourishment.
Kyle wanted to do some chopping on my car....I told him no and he got so mad at me he went out and bought a couple of his own.
Your combo intriques me....it runs so well. You use Cal Tracs, yes? What were the et changes in them, by themselves? What were you using before?
It seems to me, that for the price of Cal Tracs, one could go to a good ladder bar setup and be better off. But, I know you win quite a bit, and are incredibly constistent with them. What are your thoughts?

Your combo looks like it should be going faster than it is. Look at 383man's combo, he's got a great old-school combo putting down excellent numbers for a street/strip car. Nothing fancy there except for some well matched components.
Maybe that cam of yours is hurting you. You say it'll diesel if you run on 91, and with all that duration that makes me wonder. You've got enough duration, but on that 112 lobe seperation you are hurting your top end/mid range.
Thank you for the kind words Daytonaturbo. Ron

Here's one for you with almost all stock components. I run it in a 3700 pound (with me in it) Road Runner. It has a 727 (flashes at 4200), 4.30 gear,
Combo is:
.040 over stock 440
Stock crank
Probe 12.5:1 pistons (actual ratio is 13.1:1) pistons have .990 pins.
Stock rods (non-six pack) that have had the beams ground, bushed,and balanced.
Professionally, race ported heads (452) with 2.14/1.81 valves.
Comp Solid roller cam #23-742-8 .262/.262 @.050, 110 lobe separation, installed on .105 centerline.
Heads are 452's with Crane gold rockers (.015 tapet lift).
I run a stock (non-port matched) 6 pack intake. The carbs are stock with threads tapped into the metering plates for easy jet changes (Pro Max Carbs).
I have run a best ET of 11.178 @121.55 at Atco in NJ. The elevation was just over 600 feet. The car was run with M & H 275-60-15 cheater slicks with open headers (uncapped 2" street Hookers).
The best 60' with this combo is 1.613.
I know the compression ratio is high on this. And yes...race gas is hugely expensive, and I hate the fact that I rarely street drive the car. The truth is, the six pack is not set up ideally. I believe there are 10's in this combo with a good 4-barrel and single plane intake. I wonder what it would do with a 10.5:1 ratio. I bet it would still run low 11's. There was plenty of tire spin with this combo, and I only ran it at the track once.
The reason there is so much compression is the 452's had previously been shaved .100" to gain compression on another combo. I put this together from used parts that were sitting around our shop.
I think if you built a similar combo, but used your Eddy Heads, an M1 or close, and your 850 Holley, you'd be running 10.80's.
I plan to find out what the combo will run with slicks and a good intake and carb combo soon.
Good luck, and the 'lite looks awesome. What color is that?
Tom
