Getting ready to install my new Hughes TH 400 and wanted to know how you guys dealt with your flex plate? New one? Or did you redrill the old one?

 

Do you hav pics for us???

 

I used a TCI flexplate with my TH350

 

I went with a continental ls1-to-th400 converter. Didn't have to drill new hole, elongate any holes or use spacers. I am going to get the tci flexplate just for sfi cert though.

 

Did the LS1 just bolt right up? that simple on the th400???

 

Yeah, it is the same bellhouse bolt pattern except you only use 5 of the bolt holes. The only thing is that the ls1 crankshaft is .400" shorter than a genI chevy so you need a spacer or a converter built with the correct face plate.

 

I used a tci sfi approved flexplate.

thanks guys

 

Invest in a good flexplate, I have a billet steel one peice flexplate made by meziere. Its worth the extra$$$ knowing my foot is safe. I also have the JW Ultra bellousing on my th400

 

I also have the ultra bell on mine. with some other nice parts.

 

how much was the bell housing and do you have a link?

 

TCI here

 

around $200-$300, Search JW ultrabell on

 

Thanks Man....
