86 k5 305/350 swap

[Justin Fleming]

I had a few more questions:

1. can I use my 305 harmonic balancer

2. I am using the 305 exhaust manifolds, what or where do I get a plug to plug off the old oxygen tubes that entered the manifold. The tubes are rusted through so I cant just bend them over.

3. flywheel. Should I use the one off the 305 or put one on from a 350. I have a nice high performance one.

4. I also have a harmonic balancer that is brand new from a 383 kit that I bought alongtime ago. however it is smaller od than what is on the 305/350. could I use the smaller one or no.

thanks in advance

Justin

1) I think you can, as long as your timing tabs are the same from the 305 and 350.

2) I think the plugs are just pipe thread, if so, any hardware store should have some.

3) As long as the teeth count match up to your starter (153 or 168) it should be fine. Is the HP one stock, or balanced to another rotating assy?

4) Depends, if it is an internal balanced Dampner, you could use it. If its external I'd say no.
