It's faster with the 950 over the 750.
Got it to go 12.11 with the new 750( air was terrible)
Ended up at 11.91 with the 950. Best 60 foot to date with car on that pass.
Didn't have a chance to jet it down, know I left ET on the table, but with moving timing around and swapping carbs around it was enough for one night.
Car acts funny with the 750, doesn't rap crisply, accelerates lazy.
Put the 950 on, in the water box car raps so quick it hits the shift light ultra fast, sounds different even, accelerates faster.

Thats the thing with the SB.... they love the air... then you just put enough fuel to it to burn right to make the power... but they love air

After the season think i am going to stick 4.56 gears in it, and remove these 4.10's. Trapping at barely 6k at the stripe
Problem is this hydraulic cam and springs are going to be maxed at 6500.
Might put a solid in it, have to talk to Dwayne about that...

What was the reason it wouldnt rev? I assume its fixed? Timing was off, guys at a shop next door used a fancy setup( digital deal) and set it wrong. I went and bought my own light. Plus this little motor doesn't have a lot of grunt from a roll in high gear. Had too high of fuel pressure( 8), changed it to 6.5, new plugs, and the 750 shiny new carb is a dog

They usually are................good deal and it would be even faster totally dialed in........the carb that is.

Still puzzles me about the 750 not working. Almost think there is internally something wrong with it. Shouldn't be that much difference( and I know the 950 is a wee bit fat)
Just surprised the bigger carb is so much better. I would have thought even a 650 would supply enough fuel.
Learn something every day..... Lol

AIR FLOW........the fuel is not the issue.........LOL!!!! I know, more air, more fuel, equals more power. My point was at 6200 rpm max, how much air can 323 inches gulp in and burn. My guess is some carb guru could probably put a 650 on this little motor and get it to run better than I have gotten it to run with a 950... Lol
