Well the wait is finally over; I have my motor back together and fired up. For those that may have forgotten or didn’t know, the first time the motor was built it had a major blow up.

Any ways there’s my combo. I can’t wait to get it to the track. I have to do a little work to the car yet, but hopefully in about a week I can take it out. We have a race scheduled for 12-11-04. I’ll be sure and post the numbers if I make it. I still have to come up with some decent tires. Thanks for the help, your support, criticism, and comments.

I need some cam timing numbers to finish loading your combination into my Mr Gasket dyno program. What is the compression ratio? Rect or oval port heads?

The only thing I can find on my cam card about timing is: Valve Timing at 0.02,
Intake Open @ 43 Close @ 83
Exhaust Open @ 90 Close @ 50
The heads are rectangular port with raised exhaust runners, the flow numbers on the heads are 345 cfm on the intake side, no numbers on the exhaust. They have 119 combustion chamber. These are Brodix specs. I think that Mike "aka wolfeplace" said that the compression should be around 9.5 or 10 to 1. I thought it would have more compresion than that, but I'm not real sure how to figure it. A buddy of mine thought it would be about 11.5 to 1. Thanks for the response.

I ran your numbers and uploaded a copy to my showroom. Here is the link. I built my first 396 using this program and when we chassis dyno'd the motor, with the 15% difference figured in for the drivetrain it came out pretty close to what the program said it would be. copy the printout from my shrowroom to your computer.

At 11.0-1 compression I got @ 5500-595HP, 6000-635, 6500-660, 7000-654, 7500-653 HP and torque was max 568 @5500

Thanks Rick, man I didn't think that motor would put those kind of numbers. Well as my luck would have it the local track decided to close for the rest of the year. I can't wait to see what this thing will do on the track. Man Rick that is one fine '67. Anybody else have any comments or input.

Madmarv emailed me and asked me to run his engine comb and he said its pretty darn accurate to what they got on the dyno. He said at 3000, torque was off 20 lbs on the desktop dyno. I know it was close on my 408 but this is the first time I ran someone else combo. Spring won't come soon enough.
I was looking at some of your pics, what kind of roller lifters are you running?
I remember when you posted the pic when the motor went. I took some copy's to work to show 1 of the guys. It's good to see it all back togther, looks good.
Thanks for the compliment on the car.

ricks_67 You have one fine looking 67. Is Whitehall close to Turbotville Pa.

I think the lifters are made by either Crane or Comps. A buddy gave them to me. This freakin motor sounds awesome. I'm having an issue with the rear yoke right now, that's what's keeping me from getting it on the road. I bought a set of those billet u-joint caps. Went to put them on and I'm going to have to pull my rear yoke and do some grinding on it to get the nuts to sit flush on the flats. Oh well thats half of the fun.

Chris looks nice- can you tell me what kind of wire looms those are ?thanks

I got the wire looms from Summit. They are R&M brand, the part # is RNM-1102P. The stands for polished. You can get them in blue, chrome,gold, black, purple, green, polished, red, and satin. I paid $41.69 for them. Thanks for the compliment.

Thanks for the info - do i need special wires to go behind the covers?

You may have to buy a set that you have to make up. I don't know if stock type wires are long enough.

Nice looking motor. I think if I had a failure like that I'd roll the car into a lake and quit the hobby, so good marks on the "keep on trying" aspect.
One note on the dyno thing was it was pretty darn accurate as compared to a very conservative engine dyno, but the one I was talking about was the "pocket port" designation, not the full port. The full port was about 20 ft-lbs and 30hp optimistic, but overall I was surprised at how well it can compute numbers based on relatively little information.
Thanks again for taking the time to test that program out for me.
And having never suffered a catastrophic engine failure, kudos to you Chris for not throwing in the towel..

MadMarv, thanks for the words of encouragement. Sometimes it would be easier to sell it or blow it up or something like that. I love this car so freakin much I just can't quit. I guess it why we all have the passion for our hobby. Thanks again.
