That was actually my original plan, I guess I'll have to take a close look and see if its a usable engine. Thanks again.
Lol 8-10 mpg seems about what I get loaded or not. I have the 4:10's as well with 727 with np205. I use it to carry heavy loads and to get from here to there once in awhile.

Part of that is the 4 brl will always get better mileage than a 2brl...unless its TINY...is because the front primary venturi of the 4 brl is smaller and mixes 'with the higher velocity' fuel better.

Thats why a TQ works so well
pick the small or large primary depending on being able to run on the primary most of the time
otherwise spread bore AVS
let's not just pick on total FPS out on primary flow

dual quad hooked 1 to 1, what is THAT going to do to my gas mileage? 
IF ya gotta ask, ya can't afford it!!!!! ha But the cool factor is priceless!!!!!dual quad hooked 1 to 1, what is THAT going to do to my gas mileage?
Apples to apples comparison.
My dad has a w150 extended cab 360 4-speed 3.55 gears 14.5 mpg. He documented every gallon of gas he put in it since new.
I had a w150 318 4-speed 3.55 gear shortbox truck 14.5 mpg.
The 360 is a way better truck engine.
Both trucks are 1978.
What makes the 974 head more desirable than other J heads for a 318 swap? I've done some searching but wanted to ask while this post is still somewhat current.

They're on the small side compared to other castings, port volume is usually around 150cc and the exhaust ports, 'smaller than a j head exh port l' but with a lot better shape qith a raised floor. J head is a great head, for a 340/360.
People lump them all together because they tend to overlook or are ignorant to the small , but quite significant... and mostly people judge them by max potential or by them flowing within 10 cfm as cast..."same size valve"..ill also add that MOST who tried a set of ported factory iron didnt have the right person performing the porting.
Sadly most who fall into that group, for that reason, will never try another set thats actually done right...in their mind they tried it and it wasnt all that.... but neither was their head porter.

Your post is the exact reason I did the project. Thanks for the kind words, and happy I inspired you to try it. Every porter did their first port job at some point. Wishing you the best with your project!

Got my Accel dual point distributor (20301 ) and Super Coil in the mail today.... I'll see how close it comes to the fire wall.

Everybody thought I was some young guy and that this was my picture LOL
It's from the movie vanishing point I think..
I am young though... make no mistake about it!
Been in this game a long time because I bought my first car, a '72 Duster, when I was 14. I gave 350 dollars worth of guns and had to make payments on the last 150
You know you are OLD when you are older than the cars you restore!!??????//// I need some cars made back in the 40's! so I can feel young again!!!????/
