engine swap?

[LANCE65]

Ok, I think I have come to a decision about the drivetrain in my '69. Currently I have a 390/C6. It has an Edelbrock performer intake,Holley 600,DS II,headers. I want to swap it out and put a 300 inliner in place w/manual trans. Looking for mileage and coolness factor. Besides, it will cure my exhaust problem I have using headers and auxillary tank on my truck.
What would be a good combo? I also dont mind the thought of EFI,but which years are best? Also is the 6 banger bellhousing specific? I know the FE wont work,but what about small block? Any advice would be appreciated. Thanks

240 300 302 351 w 351 c bellhousing are the same pattern.

I have thought about doing the same thing, but I would like to keep the AT. I have the same combo you do. The biggest ? I have is what fuel milage is with the 300 six?

I have read anywhere from 15-24 depending on your driving habits.

i have a 300 in my 85 van--c4 auto--holley 1 bbl--15 to 18 mpg--this is with the smog off--non feed back carb--ds II dist. with gm hei module--elec fan--haven't looked to see what the gears are but guessing 3.50 to 3.70 range based on pulling ability and highway rpms

Yeah, I have decided to make the swap.............now all I need to do is find someone to trade me drivetrains,or buy my 390 & C6!

What problem do you have with the headers and tank? I have Hedman headers and dual pipes using glasspack mufflers exiting out behind the wheels. Now if you want to exit before the rear wheels then I could see the problem.

You just need to either run the exhaust pipes down the passenger side like this:





...or run the right-side pipe on the outside of the frame, shown in Figs. 6, 7 and 8 on this page:
