727 Small Block Torqueflite Convertor

what you have there is a 904 flex plate....I know because I just went through all this crap LOL....the 727 plate has round holes where as the 904 has triangular'ish holes.

I have a 727 flex plate I will sell you for a hole lot cheaper than you can pick up a new one for....if you want it PM me and let me know.

I have a for sale thread up and the flex plate is pictured in the thread if you want to check it out.

as for converter.....stock stall speed is less than 2500 rpm....considering a 1700 stall converter is a bump up over stock....not by a hole lot but it is higher than stock...according to TCI,stock stall is about 1200 rpm for a small block.

do your research and shop around on a good priced converter, hughes has some decently priced converters and TCI does aswell ( I picked mine up for just under $250.00 shipped.

The most commonly used converters I see guys snatching up are 2500-3500 stall converters.... but if you just want a smidge more than stock than look at 1700-2000 stalls.

also you want to take into consideration things like what gear ratio you have,what cam you have and things like that.

TCI also sells the flex plate you need but they want a whopping $120.00 for it.

you can find cheap multi bolt pattern flex plates on ebay but......you never know what your getting on ebay and who knows if the thing will fall apart at 4500 rpm LOL.
