TH350 Front Pump

I have 200 turbo action valve body and 200 pump started rework to use 350 converter,housing is bored
for 350 bushing&seal have 200 gears cut for 350 converter need input shaft and stator changed
I was told attach modified 700 shaft to 200 drum. stator from 350 modified to fit 200 pump.There
may be better way but that's what I had came up with.Valve body is used bought from Paul Crowe
he went to PG when he went crate motor.Would sell all for $150.00. Also have some 200 pieces
I'll throw in. Have 350 coan rev pattern manual sell for $100.00.
I'm ashamed to say it but I tried automatics I'm not proud of it but maybe if I warn others maybe I can prevent them from making that same horrible mistake.LOL
I'm a stick man I don't need these auto parts maybe I can turn them something I can use.

This is all very good information on swapping internal components for gear changes, however if I can steer this post back to where we started.
Is it worth the money to go to one of the trick after market pumps or is it a minimal gain for the cost?
I see that TCI lists two options on the pumps one that is more of a modified street version and another that is for "class race" vehicles. Has anyone tried either of these pumps?
Thanks,
Chad

Chad, unless your trans is set up to operate on the lower volume pump I'd steer clear of it . Less fluid volume may result in undesireable operation, not worth the risk unless you're looking for every possible amount of power. If that were the case I'd assume you would have a purpose built trans already equipped with the low volume pump I've never seen H.P. figures in print but have been told as much as 6-8 H.P. with the low volume pumps.
