Dimensions notwithstanding, that is too much weight IMO.

Regardless of the T-bat diameter, one [of many] weak points in such a plan is the rear anchor point for the T-Bar.

Hypermiling a /6 can get you close to your mpg goal, and not upset the apple cart to the degree you are contemplating.




or search the archives for Hodroddave40's "super-duper gas mileage 318"

basically take a 318, 0 deck with KB167's, run 302's or magnum heads (I'd go magnum), a small solid or hydraulic (he used a stock 273 solid cam, I'd probably go hydraulic with a lunati voodoo 60400), stock 4bbl or performer intake, and a small t-quad. tranny, use an A833OD with a 3.23 or 2.94 rear, auto, use a low gear lockup 904 with a 2.45 or 2.76 rear.

who is it on here that has the 408 stroker, OD, and sorta high gearing and getting 24 mpg? that makes more sense than any diesel




forgot about that car...IIRC its a mag headed 408 with a hydraulic roller in the 216@.050 range, and a tquad...runs low 13's and gets 24-25mpg highway.

If you want 30 mpg and don't want to destroy what little frame your car has, use a 3.9 Cummins instead of the 5.9. It will be a lot friendlier fit and have enough power and will give you the 30mpg you want.
I have a 4BT/727 in my '68 Satellite wagon, and even in cold weather and a blend fuel I can easily get 26.
The 4BT dressed out weighs about 30lbs more than a RB eng.



that sounds neat. How about some pictures and info about thrc
swap?




Shoot me you E-Mail and I'll send pics.

Would be an interesting swap, but sounds like it's gonna be quite nose-heavy.

As far as the T-bars go, talk to Dick at Firm-Feel. They make bars alot bigger than the .920 ones. I have 1.12 bars in my hobby stock, and I believe they go bigger yet.

I really don't have enough time to stay at the 'puter to continue a thread, you guys would get tired of waiting for me to come back.
I'll send pics to you and answer any questions I can.
New complete exhaust on the "Dragon Wagon" today!!

Most are dreamers on these types of projects. What impresses me is the ones that show what they have done. They dont talk about it they do it. The do'ers get the props

Well, since we stole this thread.........
Like I said, I can E-Mail pics of my "Dragon Wagon" with the 3.9 turbo'd Cummins, and answer any questions about it to anyone interested. PM me or E-Mail Deans68plym@hotmail.com
I know of another 4BT swap... in a `73 Satellite.

I dont think a 6bt would fit under the cowl, may be better off putting the shell on a truck chassis.

If you want a weird engine swap that requires a ton of work and gets 30mpg try a honda S2000 motor & trans with a Jackson blower and stick 5.13's in the 8.75, at least it will still be fun to drive still since the motor is light and you can shift it at 9k.

The cummins makes a 1gen Ram drive like a cow on skates, I could only imagine how an A body would drive.
