350 swap... exhaust manifold problem

Talking about a CJ7....

Got a 1995 350 TBI in there today and as you can see (attached url), the stock exhaust manifolds are way too close to the frame.

Any suggestions?


The picture makes it look closer than it is but still...these wont work.

Larry The block huggers that Leader is talking about are sold at Lopers, you can get them chrome or painted either way.

Re: 350 swap... exhaust manifold problem

The exhaust manifold you show is what I call the "Y" design. Starting in the early 80's are what I call the "TUBE" design. The "Tube" design will sit higher in the block. The only problem I see with the "TUBE" design is that the passenger side exhaust manifold will need a head that has the seven exhaust manifold bolt pattern. Here are my two choices for possible donor vehicles that will have the "Tube" design exhaust manifold. The 49 state federal emission package equipped 1982 GMC with a 305 4 barrel will have the "Tube" design without air tubes or an oxygen sensor. I know this for a fact, I own an 82 GMC that had the 305 like I described. The next choice would be a V8 Chevy car starting in 1980 or newer, which will have the "Tube" design with air tubes, and an oxygen sensor.

When I did my swap i didnt have the $$ to get headers right away, so just pulled off stock manifolds from a 305 in an 80's firebird... fits perfectly fine for me and should be easy to find.

Re: 350 swap... exhaust manifold problem

The Y type factory exhaust from the late 60's thru 70's exhaust they are talking about is commonly called "Ram Horn" exhaust manifolds. There are two different styles of these, one kind will have just straight down dumps on them while the other will have the dumps (collectors) turned rearward. We have used these on several 350 swaps in Jeep since they don't take up near as much room and they are away from the firewall.
Most salvage yards that have older model chevy cars will have these.
Hope this helps.
