8 inch converter can i spray it i have a 62 nova that weighs 2640 with me in it. my friend is selling me a 8 inch ptc converter 5000 stall. my current converter flashes to 3200 on the foot brake and my 60 ft is 1.7 and i am running 7.20s in the 1/8th. is anybody have experience spraying high stall converters. my worry is blowing through the converter, i will be spraying a 150 max shot. my goal in this car is 5.90 in the 1/8, 2 years ago i ran a 6.50 on a 100 shot with my 10 inch super tight converter. the car has been sitting ever since, now im looking to play some more. i know my 60 ft needs some major help being as light as the car is.
please critique my setup i want to get their as cheap as possible.

You can spray a 5000 rpm 8 inch converter, how much, I can't tell you that. A 100 to 150 shot, is gonna make the converter react as if there was another 60 or so CI and 150 motor hp more then what it's making now.
The 5000 stall speed, what was the motor that made it stall to that? That, would be a better question to answer, and will give a better idea what it might do in your car.
It will probably work,, the car's gonna go a TON better on nuts with a 5000 8 inch converter then it did with a 3200 10 inch converter that I am sure of. I think, it will work o.k. for what you're doing, having one built is always the best option though.
fwiw, I spoke with Greg from FTI, I'm going to put one of his glides and 8 inch converters in my car, and I will probably throw a little nitrous at it, no more then 1100 hp total at it, and he said that should work really good. I still have my 9 inch UCC converter sitting here too, in case the one that Greg builds me is a little too loose... but I think it's gonna work.
All depends who you deal with, all the converter parts are essentially the same, as they all come from the same places, just different people doing different things with them.

given the weight of the car i dont think it will be that hard to get to 5.90. what would be the easiest way to get their without throwing on a 200 shot of nitrous. my destop drag software says with 2600 lb car with driver 400hp,400ft lbs and a 5000 stall the car should run 6.70s on motor, between 500 and 550ft lbs should put me on the spot with a 100 to 150 shot. am i going at this the right way or am i lost
. if i wasnt on a budget their would be a turbo under the chevy 2s hood.

It was a general statement... of course the billet stuff is totally different. And, I'll say that stuff like that sometimes really is needed, other times it's not, but one thing is for sure you're spending BIG bucks on that. More then the OP probably has in 1/2 the car.
I think the OP's on the right track. It will need the looser converter, and the n/a performance will substantially pick up from that. Spray it with 150 and see what that gets you, I think it will be enough.

I think a 150 shot is gonna be fine on the 8" with your set up. Your light weight is definately a plus and I really don't think you will blow thru the converter because of your N/A power level and your light weight.
If you are really worried about it I think a progressive shot so you can get outta the hole and get the car moving then bring it on full after the 60'.

I have, looks like this:
10.92 @ 123 mph NA
3300 raceweight
28x10.5
4800 8" stall was a Fuddle
4.10 gear in back
240/244 cam
TFS 215's
11:1
1.48
LS2 intake
shift at 7000
I would see 4800 off the brake
Car was lazy on that 1.48
150 shot wet
10.008@134
1.38 spraying 150 off the transbrake
shift at 7000
Depends on how your converter works. I had also tried a Vig around the same time and the car slowed down 4 tenths on motor and two tenths on the gun.
This car later went 10.7@125 with more converter, and went 9.8@140 on a 100 shot in hands of new owner. I went to a ATI 5500 stall and the car was undrivable on the street.

You might have a shot at a 5.9 but might take some work. 150 shot on top of a car that runs say 10.3's on motor sounds like it will get down around a 9.4-9.5 no problem. I went 5.9's in another car and it was a 9.40 pass.

the 5000 converter was never used but was built for all motor 383 small block with somewhere around 475 to 500 ft lbs of torque, and for a car around 3200 pounds.
