c4 converter

Need a c4 converter for a small block, on a budget but the bigger the better. Going on a 7500 rpm car, I'll have to measure out the bolt circle today.

need the year or the spline count(best)

I have a big spline 8"convertor, I'll be home in January and can ship it then if your interested.

I was trying to avoid pulling the converter that is on it. Don't know the spline but I do know the trans is the style with the dipstick tube through the case if that would tell you the spline.

And I'll let you know if I want to buy that converter, but as of right now that wouldn't be soon enough. Just seeing if anyone has one while my engine is out, but I'll send you a message if we are going to go bigger over winter, thanks
