It's back and slmost ready!
 
Well my truck is back from my chassis builder and I've been working on it every night after work till 11:00pm for the last week trying to get it done for this weekend. No time for celebration pics just yet maybe tomorrow night, or Thur. before it goes in the trailer I'll snap a few.

Anyway truck is now 100-125lbs. lighter then last time it was there scaled 4003lbs. with 1/4 tank fuel. last time 4128lbs. with about 2/3 of a tank. The front drag springs settled too much though and couldn't get another pair that day so I'm not running the springs I wanted for some wheels up launches :( that only looks cool but eats time anyway. Incase anybodys new or didn't see and or care to read last post I made on the upcoming changes they are as follows. Tubular front upper and lower arms (Fat Man some day but not in the budget this year), dual pistion aluminum calipers and QA1 adjustable front drag shocks, 2" drop spindles and new small block springs. Willwood master cylinder, and Willwood 4 pistion discs in the rear. Narrowed Comp Engineering 9" fab housing, Moser aluminum center section, spool, and 35 spline Moser axles. New Comp Engineering 4-link, notched frame rails and QA1 coilovers with a 31x16.5" tire in the rear now. Pro Systems Nitrous Pro IV 1000cfm carb, fed by a Areomotive A1000 pump and A2000 return reg. system, on the carb side and a Areomotive non-return system reg. for the nitrous side. And a Harwood glass cowl hood to cover it all. And that's about it, a couple of changes and a few new parts.

Wow, that is awesome!

Can you tell me where you got the adjustable valve for the rear brakes? I like the looks of it.

Thanks, it's a Willwood valve, Summit, Jegs most performance places can get them for you. I'm in Canada got mine from Mopac.

Thank Dj, saw your motor pics I was lost for words but feel your pain!!

Once I get things sorted out I'll likely go to a 180 shot and hope to see low 10's with that??

What control arms are those and where did you find the alum calipers?

Nice..... can you post up a pic of the rear showing how wide tires are. im looking to fit some bigguns and wanna see if a 32x14.0 will fit on a 12'' wheel with a 8 inch backspacing, from sidewall to sidewall they are 18'' on a 14'' wheel. im hoping going to a 12'' wheel will suck it in some and i can tuck the tire. any help would be greatly appreciated, thanks

I think they are CPP??? I got them from a board member last year. He did tell me what they are but can't remember. The calipers are Howe, and took a bit of work to fit my rims.

I'll try tomorrow if I remember and have time, still have lots to do if I'm racing this weekend. My tires are 31x16.5 on a 12" rim 7.5 backspacing and I have lots of room, tubs are 1to1-1/2 from the frame rail and I have over a 1" room on the inside and room enough on the outside to go out another 1-2" and still tuck them up. My rear is 6" narrower then the stock 71 rear was

Man that is a clean truck . What lower control arm is that ? How much weight difference from the stock one ? You know Harwood test fitted those hoods on my truck . My friend worked there and he even gave me one but I traded it off to the guy who fixed my steel hood for me . Does yours fit good against the fenders? Mine had a huge gap (you could see the flat edge of the fender seam under the hood)

Thanks, I think they are CPP??? I got them from a board member last year. He did tell me what they are but can't remember. New front end parts are about 10lbs. lighter so not very much at all, bottom arms are are about the same as the stock, they are alot heavier then they look that's for sure. No gaps on my hood, fits good that way but sticks up alot more then my stock hood, I worked the slots on my hinges to drop it down. Pasenger side still sticks up, but it needs some taken off the edges and the front just haven't done that yet. Besides that the back of the cowl didn't clear my aircleaner and I had to cut it out, must be built more for show I guess.

71,
That truck looks GOOD!! The hood really looks good on it. I wish that Harwood made a hood for the '60-'66s, as I would have bought on from them.
Have you ran it since you put the Pro-Systems carb on it? I'm kinda curious how much difference you'll see with it. What carb was on it before?
The truck really looks good with the lowered stance!!
Let us know when you make some passes with it!

Didn't see those before, might have went that route if they work and would have seen them and they wouldn't have required work to fit my rims. Too late now I guess, but let me know if you get them and they work, for future info.

Will do.. I'm not sure where to start on the weight reduction first though. So I just bought a game scale that goes up to 550lbs. Since the truck is apart for the most part, I'm going to start weighing things, then divide the weight savings by cost. Figure I'll start with the most cost effective parts..

Awesome!

Just a little something to think about, it is not legal (NHRA) to mount a fuel pressure regulator on the firewall.

The mount can be on the firewall, but it has to be designed to move the reg out min 6" away. It's not so much the firewall persay that they are worried about, the rule is more worded to move it out away from the flexplate/flywheel.

I know where your coming from though, when I first ran my old N2O fuel system I had the reg. mounted direct on the firewall and got busted by tech the first time out. That's when I built a extension to move it out 7" and no problem after that (even though it didn't look any safer to me) they were happy so I said that's much better hey, because getting on the bad side of the tech guys is a loosing battle, seen guys do that before LOL!

I hear ya, everything left on my list is expensive! I'd like to go to a Fat Man front end with coilovers and a rack, that would save around 200-250lbs. and and would like to go with an aluminum block on my next engine build. I know a glass front clip doors and such would be cheaper, I just like the all steel thing, raises eyebrows at the track, even though I have a glass hood it's not really a race hood.
