I got a 305 & T350 in a trade for some stuff and am thinking about using the engine along with a 700R4 that I have in my 1957 3100.
Thanks, all input is appreciated.

The factory put 305 with 700r4's together in fullsize trucks and even vans . | | | | | Joined: Sep 2008 Posts: 293 'Bolter | | 'Bolter Joined: Sep 2008 Posts: 293 | Go for it, it is way enough engine for around town. I had an '88 Caprice wagon with this set-up and it was really nice, even loaded on the highway.
You will not burn the tires though, ever! Even in the rain!

If a little 6 will push it around, that 305 will. 700R4 is a good choice, also.
Performance and fuel mileage will depend on rear end ratio, carburation, tire size, etc.

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.1965 Chevy C10 | | | | | Joined: Dec 2003 Posts: 1,554 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 1,554 | Should be a good setup.I am running a 350 with a 700R4 and it performes very nice.Also using the stock 3:90 rear,and the OD makes all the difference,economy wise. | | | | | Joined: Oct 2010 Posts: 33 Geezer | | Geezer Joined: Oct 2010 Posts: 33 | Sorry, did not cover the rear end.. I am leaving the stock 3.90 rear gear and am going to run 235-75X15 tires that have an overall height of 28.8".
This will give me 2230 RPM @ 70 MPH..
I will probably build a 350 later, but I have this 305 & it was basically free...
Thanks,
