New best ET at Woodburn

I towed over to Woodburn for the Mopar Nats. this morning, I made three time trails and one round, spun the heck out of the tires on the 1st TT and 1st round against Forest Fincher The 1st TT I had 11.0 lbs. in the tires and it spun so bad on the line it shifted into high at 7250 RPM according to the Biondo 400 box on the play back after the run, it did run 10.088 ET at 148.24 MPH after letting off to recover and making the rest of the run in high gear
2nd run I made sure the tires where at 9.0 lbs. and I redlighted with a -.049 light jerking the front tires out of the beams while running 8.866 at 148.33 MPH
I change the shift RPM from 7000 RPM up to 7300 RPM and change the trans brake delay from .993 to 1.00. I removed the 7600 RPM chip from the MSD three step which made it run a bunch better the last two hundred feet That netted a .037 light with a 8.862 ET at 150.77 MPH, slightly slower MPH than I expected
I spun the heck out of the tires on the first round due to me not being ready when they called us out which made me hurry with out checking the tires and not doing a good burn out
All in all I'm happy with the ET but I need to figure out where this new motor wants to be shifted at and see if there is some power missing due to ignition issues, possibly

What's the new combo? and this is in your cuda correct?

Always great to get a new bestie! And a bad day at the track is always better than a day at work!

Any pictures Cab?

Nice pass, congrats Cab.

Nice job!

Very nice Cab!

Good job Cab! Missed another one here. Life getting in the way of having fun

8.80 is hauling for a door slammer E body car. Nice looking car too. How much were you asking for the car and did you get any offers on it?

This motor is a 400 block cast on 8-25-1977 that sonic tested oaky bored to 4.375 with 440 Source aluminum main caps and ARP Main studs with no fill or girdle. 4.300 forged steel stroke crankshaft, Molnar 6.700 long forged steel BB Chevy type H beam rods with ARP 2000 bolts. Diamond pistons with a +8.0 CC effective dome, Indy 440-1 CNC ported heads with 2.25 intake valves s and 1.81 exhaust valves, Jesel paired shaft 1.55 ratio rocker arms, Bullet solid roller cam with 282 @ .050 on both lobes with .457 lobe lift on both lobes, ground on a 108 LSA installed at 104 ILC.
Indy older 400-3 intake with a custom built Holley 1150 CFM Dominator converted to E 85 by AJ at Bob George racing mounted on top of a Wilson Manifold 2.0 inch tall reversion spacer:up
I change the distributor this morning due to the old one causing hard starting, back firing while trying to start it and a lot of other ignition problems, dang Chinese junk anyways It took me this long, half the summer racing season, to figure out what was causing these problems
I'm hoping the rest of this year will go better
This motor had issues with the Mopar brand bronze oil pump drive on the engine dyno in March causing the distributor to wobble around while trying to start it
I discovered the original rotor and cap on this new distributor was bad in June after it starting to miss in high gear and the intermittent hard starting has been occurring since day one on this motor
I hate MURPHY

Good job Cab. Congratulations on the new best.

Congrats on the new best Cab. I am sure you will work through the details bitting you in the butt.

Congrats on the new best.
That’s a nice running combo.
Cam looks very similar to the old UD 680/280R8

What’s the rest of the car set up like? Weight?

It is a chrome moly tube chassis with A arm and coil over A arm front suspension with Koni steel single adjustable front shocks, 4 link Dana 60 with Mark Williams 40 spline axles, 4.56 dana Corp gears on a Moser 40 spline steel spool, double adjustable steel rear coil over Koni shocks, Power glide tranny w/Shiftnoid air shifter and throttle controller, 400 Biondo box.
Steel front end that slides off, Fibreglas doors, bumpers, hood and rear deck lid, all Lexan windows except a stock windshield.
I had Forest Fincher update the chassis this past winter to meet 7.50 SFI specs, he had it certified also
it weighs right at 2800 lbs. wet with me in it.
The Ultra Dyne cam card shows CRB 312/312-08R. Part # 503000.
The car goes straight and repeats time if I do the burn out correctly and make sure the tire pressures are correct
I would like to sell this one so I can get the back half 1966 Dart done and start racing it

Well that is good news...congrats!

good deal cab !

Nice job Cab. I was parked right next to you at the trailer, just never got a chance to come say hello. Was a good weekend.
I was in the 4 speed class and was trying to watch you guys from my car since we were right after.

Back out in fine fashion Cab! Nice passes!

!Not that it matters! ...but I can't make sense of which cam you're using? I have an older Ultradyne cam list and this cam has ANY PAIRING of the numbers you listed it is not from them. I wonder if the cam wasn't reground by Bullet and the PN is the original grind. Anyway NICE to hear you out having fun and running good!

I had remembered that as a cataloged cam from UD, but I looked in my old catalog and it’s not there.

Then I remembered the two that I used were just something I had ground.
Only 3 lobes in that lobe family, 296, 308, 312.
The 312 is listed as 280@.050, but since they didn’t use different(bigger OD) masters for the BBM core size, it would grow 2* @.050 from the design spec.

Listed as 312@.020, 280@.050, 201@.200, .4567 lobe lift.

I had really good results with those.

The 311R8 was also quite popular.
Very similar, but slower lobes.

Damn, I'm definitely coming prepared to stay on Saturday next year. It snuck up on me this year and I was there Friday for the test and tune.

Hey Cab, what is your compression ratio? I love E85 but I've only run it on turbo motors.

Congrats on the new best Cab ! Ron

It is close to 15.0 to one on 7 cylinders and close to 14.5 to 1 due to combustion chamber volume and deck height differences, it is not perfect
I think I will recheck all eight cylinders again to make sure on the true compression ratio
EDITED: I recheck all 8 cylinders on the compression ratio on United(KB) web site and it has between 14.56 to 1 lowest with 15.01 as the highest compression ratio due to deck height and combustion chamber volume differences

Way to go Cab! You still have it!

Wow!

I had no idea that E85 would support that much compression. That's impressive.

I'm thinking of upping the alcohol percentage to 90+ % to see if it will go faster or not with that mix

Good idea to try e98, or the highest you can get. I have been told there is better performance with pure ethanol, but never switched from methanol to see how pure ethanol and methanol compare.

Cab- Do you have photos of your cars available somewhere??

I do, but I don't know how to put them on here

Sorry for being late to the party. That car's haulin' a$$!

Cab, big congrats on the new best. That's hauling the mail with a stock block build😁
Back to the ethanol; it lands somewhere between race gas and methanol for power produced. Best thing though is if you can buy it directly from an ethanol plant? Never done it, but have been told some plants will sell it that way if you bring your own barrel. Then you know exactly what you have. Mix in 1 at Klotz and you are good to go!

Good to hear you're back at it.. I would imagine once it's all sorted out it's going to be fun

I have this one...no action shots from Woodburn though...
