My boss is looking to build one from a LQ4, looking for bottom end kits? I know TSP does, any others?
I'm thinking L92 heads, but I'm not sure, I really don't know much about strokers. I know L92 heads can act "funny". He wants to stay Carb.
If someone could point me in the right direction that would be great, and yes I did a search, I wasn't able to find much info.

Thanks.
