1968 chev swb - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Dude68** · 10-10-2011, 05:13 AM

Just hauled in my 68 that was purchased new in 68 . He had an engine exchange as well as a transmission exchange, otherwise I am all original. Now I have had this truck parked since the timing gear broke. I tore into it pulled the head a nd took it with me to have the gear pressed on the cam and head redone. Long story short head was cracked nobody could match my motor with a head so the truck sat in my driveway until I moved a few months later. And of course I moved to a neighborhood that did not allow stalled vehicles or projects In the driveway. So the truck was sent to a friends where it has been for 16 yrs. But I got it yesterday and it is in my dads new shop. So my dilemma is do I try to fix thie exchanged motor, that appears to be a 235, or put my 350 in there that I rebuilt a few years ago for running a dirt track car. If I go with the 350 I would like to change to an automatic trans as well. .???

I guess if I had a 350 on hand and a broke six cyl in the truck I would use the 350 as long as it wasn't too radical. Just get a th350 auto trans and put in at the same time.

i vote 350, i did this swap out a few years ago.... have not missed the 6 cyl.. u will be glad u did..

My vote is the 350 also since the truck isn't stock anyway (235 engine).

You need to check your rear end ratio. A lot of those sixes used a 4.11 or lower ratio and your truck will rev pretty high going down the highway with the 350. May need to change to a friendlier ratio or go with an overdrive trans.

put the 350 in and a 700r4 and you will love it! And welcome from a little south of ya in Jefferson AR!

**Dude68** · 10-10-2011, 09:56 PM

Is 700 r4 an overdrive transmission? What kind of steering column will it need?

**Dude68** · 10-10-2011, 09:51 PM

Its a 4:11 positrac rearend. I like the three speed, but think an automatic will work better.

**Dude68** · 10-10-2011, 09:53 PM

Does anyone know which mirrors were stock on this truck, round or square?

faribran · 10-11-2011, 11:17 AM

yes, it is an overdrive... and a stock column will work...
