Alright So I found some HC pistons for a steal. I've got a couple questions. I searched all over the Patrick Racing web site and couldnt find the answers so naturally I came here. The part number for this kit is an old p/n and I can't find any info on it but it's a complete kit. What do I need to do a complete HC swap. Do I need cams? Head work? Crank work? Valve springs? I know Alan H is going to look at this post and put up about 500 hundred links. I searched High Compression pistons in the forum and didnt get the answers I was looking for. Anyone that has done this mod, please help. The Patrick Racing p/n for this kit is 3004 or at least thats the number that this company is listing as an OLD STOCK item..I'M also having problems determining what the overall compression ratio is. I've got an email in to the company selling the kit..no reply yet.
