I actually found a shop who was willing to do either a custom port and polish job on my existing intake manifold , or, using it as a template, build me a custom unit. I haven't sent it to him yet, but I will be doing so this week. He works in a race shop in florida, here'* the link:
I have a 1991 Buick Riviera, in cherry condition. The engine is a brand new factory crate Series 1 Supercharged. I will most likely be sending him my entire head for a performance rebuild. Who knows, since it'* in the crate I may just send him the whole thing and have it Dynotuned too! (pipedream) Wouldn't that be something?
I cant say as I will be back this way again as I am always on the go trying to find a bigger and better performance part for the engine the world forgot. By all means though, if you have found anything really cool, or you want info on my progress please email me email@example.com
. I look forward to trading success/failure stories with my fellow series I owners.
