FED Build

<< < (5/12) > >>

JEFF/21C:
i've always use 10* inclination and 10* caster on all straight axle cars dirt,drag and ice except for fed caster was set at 12* camber varied 0*-neg. 1* alway handled well.

Still chipping away and making slow progress. I got the rearend and engine jigged up with an alignment bar on my chassis jig. I got the carrier bearings pressed onto my spool today after needing to make tooling for my press to seat them all the way. There always seems to be "just one more step" necessary to get anything done.

I guess I need to buy a dunce cap. I was going to remove my ring gear from the open carrier and didn't notice the giant "L" on the ring gear bolts indicating (thank you Mopar) left hand threads! I buggered up the threads in one of the holes and stretched out most of the bolts before I realized why they weren't loosening up. Doh! So, now instead of "wanting" a different ring and pinion, I "need" a different one. I'd perfectly happy with a used but useable ring and pinion for a 741 case (already have a coupler for 29 spline pinion) and would be interested in 3.23, 3.55 or 3.73 or other ratios that would work. Car is for bracket racing so optimal gear ratio isn't quite so critical. Let me know if you have something and please include price and photo(s) if possible.

Thanks!

I got a few other projects finished up (including my ring gear/spool issue from the last post) and now have a window of time to really make some progress on chassis building. I'm starting with the shoulder hoop and will be working from the back forward. I don't think I'll ever see the need to have my car certified since all I have in mind is bracket racing at unsanctioned tracks, but I'm pretty much following S&W plans as well as construction info from an AHRA rule book, which appear to be copied, from what I've seen, from NHRA. Remember I'm building a 10+ second 1/4 Mi. car but will only be running on potentially 3  local 1/8 Mi. tracks.

My understanding is that the chassis construction regulations/requirements pretty much stop at the mid-plate, or possibly at the front of the engine. Is that accurate? Believe me, I don't have anything crazy in mind, but does a builder have flexibility on chassis construction forward of the engine or mid-plate?

Finnish Fireball:
You got that right, only the cage and cockpit area matters. What comes to never needing a tag and only 10sec comments, I strongly recommend a second thought. Trust me there will be a day you want to go faster, we all have been there done that. There will also be a day when you try to sell the puppy. Hundred times easier with cert. And the list goes on, do it by the book at once. It's a lot easier now than upgrade later. 7.5 sec spec for mild steel is not that bad. It will cost you just as much time and money to fab an unsafe backyard hackjob as it does the other way, when you are starting from scratch.
