sling shot 383, no nitro just alky,was recommended a 6000 stall, have 5000 now,just looking for input from guys that have them

8 inch
I have similar combo--I have a 6000  OK now remember  that is 6000 rated WITH my torque and combo--put it in different combo and it will act totally different--converters are like rubber bands--lay the torque to them and they are very different than if behind a milder combo--You need to consult a converter maker not guys on a forum--They will ask you a zillion questions and try to build a unit to work as best they can ---my experience is that dragsters and very light cars like ours are very different than launching a 3000 lb bracket car--in our deal LOOSE is GOOD!!  You just about can't get too loose--totally backwards from door car deal--Our cars love to have a super loose unit and..by being so light just about anything will work well in our cars--I have seen club members run within a few tenths with cheapo tight units and expensive custom units--The cars are easier to drive and seem to launch and act well with crazy loose units--it is all about the car weight


 Kenny at PTC  (a great outfit ) will build you a very high quality converter for less than anyone and stand behind it----they also seem to understand dragsters
Many get them too tight
soft hit just means less tq multiplication I think  also good for our cars
Talk to the experts but if you get an 8 inch for a few hundo grab it and never look back

Also think about used units --they may or may not be set up for use with a plate and then thickness is an issue --you can space a std unit with washers etc and be fine  Coan makes a spacer kit with a piece for the hub as well --value priced as well

You did not say who recommended,probably on purpose.My new converter is from FTI.Its set for 6600 stall.This is for 225" FED with 526 hemi,alky injected,powerglide w/1.69 and 4.11 gears.How well does it work? can't say yet.

FTI is run by some smart guys--they have some very informative videos on Youtube about Powerglide pumps etc--I understand they build a great converter
I have always used Kenny at PTC for GM units--I Think JW, Coan, and Lupo all do nice stuff can't forget about ATI--they build form all new stuff no recycled cores and if you need a class winning super scienced unit they are hard to beat--think spragless on any custom you order--they are Tough but at a cost.
I ran a door car for over 25 years--the converter in a winning bracket car is THE key piece to the entire deal BUT..in a light weight dragster almost anything goes looser the better so that makes our lives much easier than door car guys by far! Continental on the west coast ( I am an east coast guy) builds super units too--I actually have one in my car now and just LOVE the darn thing--never bought form them new but..
