6262 Gen 1 JB turbo converter help

[TireFryer]

Scored a 6262 jb turbo for $100 along with a roller cam. I’ll be finishing my engine with ported heads and a different converter. I have a friend with a 2800 stall lockup. I’m already blowing through my ancient Vigilante 3200 stall at 24psi with my blown te62, barely drops 300rpm on shifts at wot. Single disc so I can’t wot lock it. Is a 2800 stall enough for a .63 ar housing on a 6262? Thanks for any input. Mods in signature with the addition of a 212/212 roller cam and cnc champion iron heads and this 6262 and e85

Think you should be looking at a 3200 non lock up for that combination
Maybe a 9.5” PTC 17 blade ?

I ran a 2800 AC non lock with my 6262 JB...but I know how to tune. Most will need a 3200. Most LU's slip like a whore unlocked...hence why guys were always wondering why my MPH was better than theirs.

I’m a good tuner. I may look into a non lock. Any mods needed to run a non lock converter?

What's the combo. in the car now that you are wanting to use the new 6262 with?
My Vigilante 0 pump 3K stall dropped 475 rpm on the 1-2 shift racing, locking it in 3rd gear around 85mph dropped approx. 700 rpm.
RWHP at about 400.

Forged pistons. Stock crank and rods. ARP main studs and rod bolts (line honed). Roller 212/212 cam. This new 6262 turbo, champion cnc iron heads. Champion ported intake. E85. I’m blowing through my vig 3200 and it’s a single disk, not made to lock at wot.

when you say it drops 300 on the 2-3 shift, what RPM is it shifting at?

Yes. Talk to a trusted 200 builder. it's not much. The TC is the most important piece of the puzzle. Most fuck it up.

The stock short block can handle bottom 10's all day with zero KR. Bison will tell you the same. Eventually the stock piston will crack across the top of the piston along the piston pin. The worry is this. The more you bore the block...the closer you get to the water jackets. I picked up a used .030 over short block from a local and cracked into the water jackets twice and sleeved it...and the third time it cracked a cylinder to the top of the block and I had to scrap the block. No one beat on these blocks more than I did so I know their weaknesses.
