engine location
dreracecar:
2.4 spec is plenty, it allows you to run down to 6 sec and a decent size tire because if you plan to sell it a a fuel chassis the rear end and engine plates will have to be re-located because of the spec tire size (smaller).
Now
If you want to make it 2.2 spec capable , cross reference 2.2 and 2.4 where it applys to same components and match dia and wall thickness, but leave any extra tubes that the 2.2 spec calls out for and worry about those at a later time.
Honestly I think you need to go out and buy a car first and start running it
1) its going to be cheaper then building new
2) will prepare you to what changes the new car needs later
3) get you racing so much sooner, If you dont have enough bank to buy a very decent used car now, It will take you a year or two to finance and build new car--- and things change in those 1-2 years

JrFuel Hayden:
Well, my thoughts on engine location has more to do about the kind of power your combo will make. A number of racers suggestions here are talking under 40", which might be race cars built in the 60's, and maybe TF, when tires and tracks didn't have as much bite as now. Also most of the talk has been SBC motors. If you are going to run 454-460 BBC you will be making more torque than SBC, so I would think your motor needs to be a little farther back than the 52-60" out combo's.
If you have time, you might want to come to Bakersfield for the Hot Rod Reunion , Oct 20-23, and look at the 7.0 cars running BBC. You might also talk to Dave Tuttle, [ 530-547-2402] he is near you and has built not only our JF [ 48" out, iron SBC], but the winnest A/F car also near you, the Bates/Adams injected Nitro Hemi. I would think your unblown BBC on alky would run 7.0's. Art [RIP] and Mike Chrisman ran a 399 ci BBC , all iron, JrFuel car a couple of years ago, and they ran 7.30's with it about 150-200lbs over weight. I told Art and Mike they could build a bigger motor, now that they increased the max engine size from 410 ci to 430 ci, I would put a longer stroke in it, like 427 ci, which would help them make weight, [ 3.5 lbs/ ci] and help build enough compression, alky likes high compression.
If you would be interested in running JrFuel, please call me , 805-444-4489, we have a good program and great helpful teams, along with sponsors for the JrFuelDragsterAssociation. If you should decide to run JF you can also race B/ND in Comp Elim, besides working your way up thru NE-1, 7.0 Pro and JF.
Bruce [ dre] is right buying a used dragster will be cheaper and faster to race. BTW there is a great FED car near Sonoma for sale for allot less than what it would cost to build. It's a west coast copy of a Neil & Parks JF, Frank Parks agreed to advise Bob Lander as long as Bob was going to build a JFB car and not JFA like Frank and Scott were racing. It is light , like 1355 lbs with the 165 lb driver and an all iron 387 ci SBC, and has run 6.96. The complete roller is for sale with or with-out the incomplete SBC. Bob Lander is in Sebastopol Ca, 707-486-9875. It might be a good combo for you with the motor out 50", and since Bob built it, if you would need some mods he could handle it. Again call me I may know of another car for sale, that is around 42" out.

noslin:
thank you for the replies. i understand the simplicity of buying a roller that has been on the track already. i have searched a little bit on the net for other roller FED's. as it stands right now, i think i can build a roller for about the same total out-of-pocket cost (or cheaper by hair) then to buy someone elses car and have it modified to fit me and or the cost of picking one up out of state (shipping). im 6'5" 205lb. so, anything i get ill have to have it modified for me. there is one for tall guy in texas, thats going to be a 5000 mile round trip, time off work, etc.. that would cost me 3k by the time i make the trip and back. right now as a roller, ill be less then 20k. i have all the electronics already from past projects and just need the mechanical fuel stuff (hat, valves, j block, cans, etc), trans, torque converter; my buddy is handeling the motor details. nevertheless, im having Bill Comstock build me one new. although Tuttle is 5 miles from my house, i like Bill and will use him to build the chassis. I have been down the road of buying a used car, i ended up totally redoing anyways and that is the other reason i want to have a new one.
Mr. Hayden, i am familiar a little bit with the A fuel, my buddy Steve (with the nitro vw FED), has talked about Jr Fuel too with the rules, a, b, c classes. i haven't looked into either much as not at that point. never thought about being able to run a different nhra class such as B/ND, thank you for mentioning that.
man, all heads up classes are very competitive, shoot the stories i hear of even the index racing with qualifying etc are super competitive. definitely will be excited to even make any of the index fields, that would be an awesome goal first. then to make one round haha.
