I think Steve meant 215-220cc for the ported KRE heads. Definitely to big for a tractor motor

[Steve C.]

Thanks Skip, I corrected it. big differance and big impact on results.

I got those numbers from a discussion about a set of KRE D-ports that were about 323 cfm at .600 lift. Jeff confirmed it. In contrast Bob Davis KRE ported 310 cfm @ .600 head Edelbrock heads have a 236cc runner (SCE 128105 gasket/ 2.3 ports )

Big inches + big roller + small runner volume heads

With a shorter 4.125 stroke the 482 using the Edelbrock heads at a 234 cc runner volume made its peak power at 6900 rpm with a 279 at .050/.704 lift solid roller. With the new revised combo and using the bigger High-Port heads John's motor made it's peak power at a lower 7000/7100 rpm with a 285 at .050 /.850 lift roller.

(I'm trying to keep my new street 505 under 6000 rpm. Should dyno next week)

Don't know where my Desk Top sheets are at the moment but it sems it showed a peak HP(7??) @ 7,400/7,600 RPM.
Jack has told me his predictions are about 7,000-7,300 for shift points..
It's going to be a HO tractor motor !!
Think I just graduated from "streetable" motors....

[Steve C.]

Yes sir, a very cool tractor motor Really looking forward for your results to be posted. I think its really great that we share our combinations and results with the community, good luck.

[Region Warrior]

Sounds like your going to have even more fun this year 60man.
Hope to see ya at Norwalk.

"I hate to part with 8 lugs but I also have a Scarebird front disc conversion setting on the shelf. It's not the 1/4 mile tracks that get me...it's those short little 1/8 mile tracks with even shorter shut downs... Have had to change shorts all ready a few times...."

Troy, I've had the same troubles a few times on short tracks with my little old "street" car. I'm glad to see that you are looking at the brake "issue", I thought that you might have been running the old front drums. I had them on several big cars I used to race, they heat up and go out of shape quickly (causing me to have to change my shorts a few times as well), disks are far superior in every way!

Do you have a 12 bolt or Ford 9" in the works for the rear?......Cliff

Cliff: I really don't race on 1/8 mile tracks if I have a choice...although I would like to see what 4.56's or 4.88's would do in the 1/8th....
I MAY have to go with 4.30's for 505 combo ??
I plan to stay with the 59-64 9.3" rears with spools. I have a supply of different ratios (4) with Strange spools and Moser axles..
Tackling the two piece drive shaft is next project...
Can't see "down sizing".....
CYA at Norwalk...

[Skip Fix]

I'm betting the cam choice not the head cc and flow is making the "proposed" rpm peak that high. I'll still bet the head flow has it lower than the computer estimate for that CI motor.I'll bet 6500 max.
Should make that big tuna boat move on out!

To me there is a lot a Gray areas when entering data to Desk Top Dyno..
To much assuming ....I'll wait on the REAL dyno results...
505 may come sooner than I thought...I screwed up at T&T today...bounced
off a 7,300 chip and I may have hurt my trusty 462...
Only 5-10PSI oil press. at idle...sounds like (hope) I lost ANOTHER oil pump !!
It's yanking time ...again ...505 will be in the hole ASAP..
Time to move this "Tuna boat"....
Just for giggles...I saw a set a SBC heads in TN with ports that looked 1/2 the size of mine....damned things flowed 440 CFM !!! The bowls looked like pint milk containers..

[Gas455]

Hey Mate,

sorry to hear about the 462...But I know that you can't wait for the 505 to go into the bay so you can have some fun.
Did you get my email from [email protected]?

Should be going for a spin in mine tonight hopefully if the weather stays alright. it will be the first outing with the 474back in.

PS: I hope you've got good brakes on that old car, gonna be interesting trying to stop 2 tons at 130mph!!!

Since Troys running a Tuna Boat he just needs to throw out the anchor to stop.

Hey Homo......is that your new ride in Avatar ??

Tuna Boat huh ?? Then it smells OK ??

60's man, are you running stock caps on that rear end? I busted two sets, Mark Williams makes billet caps for that set up. Since I upgraded, no problems.

Thanks for the info...
I have billet caps on two set ups...need one more set for my 4.10's.
Going to try 4.30's with the billet caps this season with the 505, if tires can hold it..
I feel a little uneasy with the stock caps..
What power level are you running and is it a stick..??

Hey Greg. I got your email and sent you one as well...did you get mine ?
Did you take a ride with 474 ??

My 1965 GTO has a 455+.030 with D-port heads, a Jerico 4spd with 4.56 gears on a nine inch tire and weighs 3600lbs. The car has run 10.87@124MPH. What weight will you be running with your 60?

[Skip Fix]

60man Inland Empire makes a beefy two piece driveshaft for the X frame 58-64 Chevies. Beefy support also.

Skip I'll check with Inland Empire but the Chevy center support mounts different than mine. My drive shaft would make a beefy Chevy ..LOL
Thanks ...I will check with them...never hurts..
So far I have not had any problems..only blew one u-joint..the front one ??

[sdbob]

Sounds good 60 man.Hope you didn't hurt the motor. Bob
