Once again I am begging for ideas from folks who have been down this road before ....

We started to stuff the 350 where the stock 6-cylinder was ... block fits, pan fits, exhaust another story. We are trying to use vortec exhaust manifolds from a late-model Chevy truck but they are TIGHT where the frame bends in, just in front of the firewall. Looks like the frame is going to need heated and banged to fit these in.

ALSO, as the car was originally a 6-cyl auto ... we're trying to hook up a 4-spd Muncie w/hydraulic master/slave and it looks like we're going to have to almost run the slave behind the firewall and cut the floor for linkage clearance & then plate back over it.

Anyone else been down this road with exhaust and/or clutch-tranny? We are going the low-buck route and, since everything seems to come from mismatched sources (some truck stuff, some car stuff, all different years), we have taken to calling the car "Muttley" ....

I wonder if regular exhaust manifolds (not sure if they're 2.25" or what) would be much of a drop-off from the vortecs (it's a 355 so I imagine the bigger exhaust would help). I do not know how stock 350 manifolds would fit in regards to the frame but I would imagine they'd be smaller ... I really don't know. We can't run "headers" ....

Also wondering about clutch -- got a master/slave and an old LM pedal but the bellhousing comes RIGHT against the firewall and it really does look like the slave will sit on my side of the firewall if it's going to work at all. Does anyone else run the hydraulic or is a cable a better way to go ....

I know we are probably about the 1,274,592,175th group of folks to put a 350 in a metric Monte so we will appreciate any ideas we get. Thanks again, this is a very good board for info.

What we did with the exact same exhaust was cut the truck exhaust off just after the flange. Then we took three inch exhaust pipe and welded it to the smaller 2.25 pipe. Then we bent the three inch to fit under the car. If you want some pictures, email me at

take it to an exaust shop and have them bend you up some new pipes like he said as far as your bell housing goes you might just need a bfh to beat the fire wall a bit. do you have the motor mounts in the stock holes or did you move it back a little bit? we alway make our own clutch linkage with tubing and a rod and have no problems at all i don';t like to use hydrolics they are just more parts that can fail and then your done

we are having the same problem with the clutch. i got a push type slave out of an s-10 and still can't find a good place to mount it out of the way. racer17j can you explain more on how to make a clutch linkage with tube and a rod? this is our first car, and i'm stuck on this one. thanks.

basicly it's the same as any linkage you will find on older chevy trucks that had manual clutches just weld a tab on the frame to suport it and use the ball off of it too

I am running 97 truck manifolds and I had to cut a crescent shaped hole in the top of the left frame rail and then dent the side of the frame over to meet it and weld it up it worked fine with bolts in the manifold instead of studs.
