A lot of parts arrived today. Still have to order a few things. I tried setting up the extension for the pump and ran into fitting problems. I'll have to machine clearance at the bottom of the extension to clear the balancer. Also have to get another extension shaft for the pump. The one sent is too short and wont engage with both drives.

Pretty normal thing to do

Lot of progress today. Shifter is in and working. Throttle is mocked up and should work. Figured out how to mount the water manifold where it doesn't look bad. Also made another parts list. Seems like the parts buying never ends. All the empty boxes are from parts orders. Gotta clean up garage!

Finally got the fuel pump shaft corrected. Pump and returns mounted.

I'm needing to buy a engine diaper. What are some of the better fitting brands out there. RCI makes a SFI 7.2 # 7809A approved diaper. Does it fit well? My engine mount use the two upper mount holes on a SBC.

I have DRE diapers on our SBC FED and our 1964 Mercury Comet SS/MA 289 CID. Great guy and product. I have been to his shop. http://www.enginediapers.com/

Thanks for the link! I'll give them a call.

After getting sick and tired of fighting a blanket , mostly, between the 2 pc oil pan and rear motor plate, we added a belly pan [ with a lip] under the engine , which is NHRA legal.

Belly pans still oil the track when it breaks, run a diaper. Been there done that... Sorry John but it is true for everyone. Had the safety guys at famoso yell at me when I was just with the team at the time.

I sent DRE the pan measurements. I'm really wanting the 7.2 diaper. Hate to think about a oil down, getting burned or hitting the wall.

My oil retion pan has about a 2" lip all the way round the pan, we would have to get allot of oil in the pan to over flow. As you can see on my pan the pan gets installed on the inside of the frame rails. We also put oli absorbing  towels in the pan.
In our 15 years with this car we have only thing we have put on the track was water when a freeze plug rusted out ans leaked. And we have had a couple of busted rods.

More done today. Burndown tubes and finishing hose ends. Ordered a custom DRE Kevlar diaper. Dennis took the order and made sure all things are covered. Building this has been fun but, every time I start to finish a job, I need another piece. I thought I had enough 6AN fitting to finish fuel line. Nope, the old fittings were for Teflon tubing. So another order going out.  I plumed the water manifold from the back of the intake. The Moroso filler is just a little higher than the hoses. I'm running out of excuses.
 Took a few pics.

It should not be an issue with your application but as a matter of principle please lose the clear plastic burn down hoses. In any sort of fire situation those things will be gone in an instant. A few years back I re bodied the Boss Bird Pontiac nostalgia funny car after a fire.  They had a fitting break on the fuel pump to start the incident and the fire was bad enough but it got lots worse when the clear hose connecting the puke tank to the shoulder hoop bosses went away and let the fire get to the nitro diluted oil in the tank.

Good advice from Rooman, we use flex hoses to and from the valve cover going to the vacuum pump and the puke tank.
If you notice , on the photo, we run our vacuum system different than most others. We had Jeff Johnson build an extra camber on top of the left valve cover, because we pull the vacuum from the oli pan not the valve cover. The idea is there is alot of oil in the valve cover at high RPM, that needs to drain thru the head and block to return to the oil pan. Most other racers are pulling vacuum from the valve cover which is pulling up the engine when the oil needs to go down the engine, so you are fighting the flow of oil. Again we have a fitting in the oil pan that gets hooked to the valve cover camber that gets hooked to the vacuum pump, and then the puke tank. There by the vacuum is being pulled down from the oil pan, not up to the vavle cover.
Last year we thought we had a problem with not enough vacuum and put a regular valve cover on her, but we noticed the rod bearings did not look as good, we normally get over 100-120 runs on our rod bearings, so we put the camber cover back on and now the bearings are looking great again.  The camber cover has a few small holes into the VC to drain any oil to the cover.
Any questions feel free to call me, 805-444-4489

Thank you both for some good info. I could see where the hoses would be a problem. This is the way the car was set up before. The puke tank was custom built to fit the frame so I just put it back where it was. 

I do like the vacuum system. I might have to change to that with the next engine.
