225 Slant Six Manifold

Quoting all of you so you can see the pics.

I think these are good photos. If you want to see something else or see it a bit better, please let me know. As I understand it, this is not a stock manifold (based on what my mechanic told me probably 8 months ago).

If it’s looks like it’s the manifold that’s the issue, then I’ll probably take you up on the offer pishta

Concerning your current intake manifold, there is a two piece die cast aluminum intake in two bbl and one bbl versions that have leak issues at the seams. But they can be successfully repaired be either welding the seams or sealing the seams with epoxy.
So unless you want to go with a different intake manifold, you do not need to.
It would be helpful if you could post a photo of your current intake manifold. So we can better understand the issue.
If you do change the intake manifold, that change should be made in conjunction with other engine component upgrades. With a 4 bbl you should also consider raising the compression, maybe a better cam and improved exhaust to get your money’s worth out of the larger carb.

I went the 4bbl route,if you do be prepared to spend more money than you think you will(alot more). If its stock its most likely a 1bbl carb with cast iron manifold. Pics would really help.

If you upgrade to a 2 or 4 barrel, you will also have to change the gas pedal linkage over to a cable vs the solid rod...

if you need a good iron 1bbl intake, I can mail you one for cost. Probably <$22.00
