I've had really good luck in the past with A 1 marv does a hellva good job .he's no stranger to Buick stuff.the converter that's in my car now is a continental which works fine . Just my .02.
Have had one ATI 10" since 1990. It has too many passes to count behind 600+ Buick HP and has been sent back at least 3 times for a stall change (had to change the cover it had been cut so much). I'd go with someone reputable that does this as their primary business as they can be more responsive, accurate and provide very fast turn-around service when and if needed. Cheryl
Ultimate Converter Concepts --ask for Lenny or Dawn and tell him John from the Northeast GS/GN Buick Club recommended him. Great one on one customer service. They are the best and they know Buicks.
ATI,Coan,PTC , just like anything else, You get what you pay for. I have an ATI treemaster in my Wagon('65 Buick special).:3gears:
Deenice, You will get many differing opinions on converters. I suggest when asking about who makes a good converter, to also ask what kind of % of slip they are getting with the converter. Any converter will get the car down the track but the difference between 6% slip and 12% slip makes a big difference in ET. My vote is for Continental Converter in California. When this converter was in my 2850 lb. car it had around 5% slip. In my 2350 lb. car is has about 3.5% slip. Good luck with your search!
Protorque convertors, Neil Chance convertors, are some of the ones that the worlds fastest doorslammer cars use.
X2 I vote for Continental also. Chris is a good guy to deal with and has been in the business for 45 years He is also familiar with the S/P converters. Bob H.
Would have to go with ATI for first choice. Have had good luck with some others in Chevys and stuff but you can't beat the quality of the ATI that I have that has been raced since 1995. Only sent it back once and that was because I was feeling gulity in 2008. They found no problems and have always been great to talk with about stall and lockup. Not many people would tell you what you had was about as good as you could get. Most would want to sell you some new, greater deal even if they knew it would not be faster. One thing about having a data recorder that keeps up with stall and lockup, you can keep up with what's going on your self and know when something is going wrong with a convertor instead of guessing. My 2 cents. Jim Netherland
Jim, A data recorder is a must for the guy who races often! That may be my next investment. I can only use MPH, Tire Circumference, and engine RPM to make the % of slip calculation. The tire circumference is a big variable in my calculation because it doesn't factor in tire growth. I assume your data recorder will monitor engine rpm and drive shaft rpm? If yes, what kind of % of slip do you get with your ATI? Thanks!
Hey Richie.... yes.. a few flashbacks!!! On a side note... if I knew that epoxy would hold up in your intake port runners, i would want to make some changes:idea2:
Yeah I hear ya ...I don't know if it would hold up either.looking back on it should have just had it welded up & been done with it .oh well. Guess will jus have to drink it now EH ? :beer
Unless your running boost, epoxy will hold, but if worried call this guy http://www.marcellamanifolds.net and ask him on a price of welding it, he is one of the best I believe. Just check out some of his pictures and you'll see why I say he is one of the best. He does some of the fastest car on the planet and some of not so fast too. Good luck.
Yes I get driveshaft and engine RPM, slip is at about 9%, transmission fluid temperature will make a alight difference. Jim
