I am going to install a Circle D 278 mm 3000-3200 stall in my 02 SS Camaro. I plan on installing a SFI flexplate too. Does anybody have any experience with the Speed Inc house flexplate??. Is it a solid part or should i get another brand name?? They cost $120.00. OR== is the stock one good enough? I keep reading that they will crack etc etc.

 

IfYou have an 01-02 fp then you need a new one. Just did my install and there was cracks in the teeth above every tc bolt. Yank recomended a ls3 fp from gm. Its not sfi rated but it is good for plenty of power.
The speed inc is (or what I thought) the cat power ones that went out of buisness that sold for like 60-80 bucks on ebay. If they still have one I say go for it. If they still had them I would have taken one when I called them.

 

i was told by two converter companies that the stock ls1 flexplate is good for up to 600rwhp... if its cracked then replace it. if your making close to or over 600 then replace it. if not then its good... stock flexplate here...

 

Lets not get that confused with the older style fp. If its a 01-02 fp then replace it
Do a search and you will see

 

I was told by Speed inc last week that they don't have any of there brand fp in stock. I ended up getting a TCI fp. I was also going to keep my stocker. But after I looked up what a stock fp can do, I thought it would be best to just replace it. Cheap insurance I guess.lol
