you gotta get the stall regardless of motor...So $300 or so IS CHEAP.

You will need more than a 400 crank, you will need pistons and to clearance whatever block you use it in as well as balance the entire rotating assembly.

Youre looking at $550 for cam, springs, and intake. Proform 750 $500. $500 for the converter. And it likely get you 8.0's.

You can run a stock 400 crank and rods (5.565") and a stock 350 piston to get a 383 though not ideal.

DO NOT listen to the dope smoker and get a 4000 converter as its waaaay more than you need and will only hurt you rather than help. Sorry 420 man but your plain wrong about that its a heavy ride......

A 2500-3000 converter is PLENTY for your package and the weight of your car, also dont waste money on a camshaft thats too big as well. Keep it simple and use a moderate hyd roller in the 238*-244*ish @.050" range and around .525-540" lift at most with your heads and compression that should be more than sufficient. Bigger is not always better, and when your heads flow a certain max number at a given lift going more lift will not increase flow or power in any way shape or form so its a watse on can actullly cost you power down where it really counts on an engine like this.....

There's a place called Redneck that makes some very good converters for the money, and you can find them on eBay they have a store. VERY GOOD for the money, I had so spend $1200 for a 9" Continental Steel stator nitrous converter LOL! So be thankful you can get away with a very modest converter......

Sounds like a crappy converter, if its built right it should not break and last a long long time. Assuming the fluid is changed after each trip to the track.....

Both if possible, I sometimes install a tiny pipe plug to drain the converter, though you get an idea of how things look when you drian the fluid from the pan as its the same throughout. Its not really a must to change it after every trip, but when your making over 1000hp at the crank its not a bad idea to keep an eye on everything. Better safe than sorry IMO... I always have several gallons of Mikes fluid on hand, and that stuff aint so cheap if ya know what I mean....

A Mikes Transmission is by far the best I've ever owned and a bunch of my buddies agree, I even had a Rossler TH210 in my drag radial 71 Chevelle when i sold it and like the Mikes better.

never heard of mikes either but i currently have a redneck th350 & stall that flashes around 4300 and have had no troubles from either. like above, if you get a good convertor then you will be money ahead.
