Is the absence of 700R4 a deal killer? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys,
I've got a chance to pick up a fairly nice 86 SWB for what I think is a very reasonable price. The only draw back that I "think" it has is that it has the TH350 rather than a 700R4. I was really hoping to find one with the 700 in it, but couldn't within the price range that I have fixed for myself.
Question is, is the 700R4 such an enhancement or improvement to the truck that I should skip over this one and keep looking, or should I go ahead and take it with the TH350? The transmission is the only thing holding me back at the moment. Thanks for your ideas.

Not at all. It won't get the gas mileage that the 700R4 will, and it wont have as good of acceleration from a dead stop, but the performance and gas mileage are still very satisfactory provided it has a rear end gear around 3.08.

Does it have a V6?

If it has everything else you want and that is the "only" thing that's not to your liking then go for it. You can always change the transmission...

Or rebuild the th350 5 times before you get to the cost of a rebuilt 700r4.

Well, all of the information I've provided you guys so far was from the owner over the phone. I actually went and looked at the truck today and it was indeed a 700R4 tranny

On the down side, both cab corners are going to have to be replaced.

I'm gonna pick it up tomorrow.

ive always preferd the turbo350 over a 700 r4, minus the overdrive

My guess is that the tranny is a Turbo 350C unit. That is a 350 tranny with a lockup converter. (look for a wire connection on the driver's side of the tranny above the oil pan) These are decent trannies, but the 700R4 will gove you a better RPM on the highway. Odds are the rear end gears will be around the 3.08 gear ratiio and if you decide to go with an OD tranny later the gearing will suck your road worhtiness to death.
