440 motor for the 63

[66 Cornpicker]

Just finished the dyno session on saturday before Christmas on the street motor for my 63 and could not be happier. 440 short block, 9.8 comp. KB pistons, 452 heads topped off with Rick Allison's A&A cross ram. Made an EVIL 666 HP and 603 TQ on pump gas from Shell. The kicker is it made 500 ft. lbs. from 2500 to 6500, real nice flat torque curve ! I have to thank Scott Koffel and Dave Cunningham (Woodruff Carbs) for all the help with knowledge & excellent work. Dave's carb work & Distributer re-curving really brought it around into one nice street motor. Scott's magic on the 452 heads helped tremendously along with A&A manifold. I'm going to have to find a good source for rear tires !

Nice. Who did you use for the Dyno work?

so what ci is it 440 or bigger ? thanks

whats been done to those heads? flow numbers?

 

[66 Cornpicker]

The bore is +.040 only because it dropped a valve and nicked that hole. It completely caved in the combustion chamber so the head was not repairable, they were 906 heads and I have a real nicely done one if anyone had a similar problem to match there 906. I figured since I plan on driving it all over and to work I found a set of 452's from a motorhome and Scott installed a larger intake valve and did some bowl work and matched to A&A cross ram intake. I don't have the flow #'s here with me but I will post tomorrow. They really work great with the long intake runners & cam.Could not be happier for not alot of expense ! I'll post flow #'s of the 906 head also. Thanks for looking

Daniel, I don't know how to scan & post a sheet but I'll give you some numbers to compare.The 906 intake peaked @ 254.15 at .600, the ex. was 181.54 at .600.The 452 intake was 278.07 at .700 , the ex. was 205.01 at .700 but the real story was how much he picked up the low & mid range flow, I think that contributed more to the flat torque curve. The cam was a roller with under .600 lift but 260 dur. @ .050 and 110 lobe center. I hope this helps answer your question.

@cornpicker you can take a clear pic with your phone and post it like any other pic. And maybe do one or two of the car and engine while your at it!

 

[66 Cornpicker]

What phone ? I'm still stuck in the late 70's ! LOL but thanks for the info, I'll try to get one of my buddies to get on this site with a couple pics.

 

[SlingLow]

70's? Not a bad place to be. I 'grew up' in the 70's.

Year ago I dynoed my crossram motor. 498", 12-1 compression, untouched Indy-1's, .660" roller cam, original max wedge port window crossram. Car ran a best 10.18@133. It made 657hp@5750 rpm. Acording to Wallace those numbers are pretty close to the dyno numbers.

Doug, I'm really looking forward to driving this car this year. I have a set of slicks mounted on steel wheels and I plan on bringing it out to Norwalk & 42 for the Mopar events. I have the invoice for the convertor from Turbo Action and I'm hoping the convertor will work, again this is 90% street driving getting hamburgers ! If I got into the 11's I would be super happy, I will stop over and see you as I've allways admired your car and it's performance and I have talked to you before when your son was running the 4 door @ Norwalk. Take care

i would think that thing would run low 11's by accident.
