Check this out folks. Ive got a 1991 Camaro RS V6 with a 3.1 breathing its last breath. The good news is.... I've got a 1970ish 350 possibly from a Chevelle but currently in a 71 RallySport. Somebody say project? I've heard that only engines with center-bolt valve covers will work with third-gens whats that about?? Assuming the 350 works fine in this Camaro, Will this old block mate to a third-gens V8 700R4?? Is this the same bolt pattern? Will a V8 700R4 need a different torque arm? Another thing... I know Im gonna need a larger radiator, but hows the fan setup gonna be? considering the 350 uses a belt driven fan and third-gens use electric fans. Thats all I can think of for now... Anyone with any info?...id greatly appreciate it!

any ch*vy motor will drop in , realatively no prob.
tranny will bolt up
same torque arm, might want an aftermarket one since you're already under
keep fan off block & just use the electric one
put on some subframs also

swap out factory tach w/one from 8cyl model, or get aftermarket.

Anything else?....Anyone?

You might want to find a set of Z-28 springs. Your front springs are designed for your 3.1L engine. With the new found weight, your front end may dip down too far, not to mention throw off your handling. Some people do not change the springs, but if your an avid driver and notice the little things I would say change it.

I would begin to worry about how your giong to wire in your guages using this 71 engine. Few other little things would include motor mounts, and using the eletric engine fan over the stock accesories one on the 71.

Got some springs. Plan on using Thirdgen z28 gauges, or aftermarket. and plan on keeping the electric engine fan, only going to rig it with a manual switch.

Good then. I think your set and ready to start the upgrade. But there is still giong to be a lot of things that will be needed as you go, that you will not thing about until you get it all in.

Good luck with the swap.

So any other suggestions from anyone??

No suggestions but a question. How are you planning to get it through smog checks?

RBob.

Smog is not a problem. Thats all Im gonna say about that. lol

Im wating on a V8 700R4. Is there any preparations or mods I need to do? I should be able to keep my shifter...I know I need a new yoke.... But what about TV cables and so forth anything?

... what about exhaust manifolds? will v8 manifolds bolt on to my v6 pipes?
Need new alternator and bracket right? I know my power steering can stay, master cylinder can stay, new starter right?
