Building Revs

[Bonzo]

I have a faily standard 289 in a 67 Coupe 3 speed auto. I have run her down the 1/4 mile a couple of times now and really enjoyed it.
Next week I am planning to go to a RWYB and thought I would practice my lauch on a quiet bit of road which has tarmac.

Two things happened ???

# I struggled to build the revs up to 2000 rpm. but it ran freely when driving on kick down etc.

# Rear paaenger side wheel spun and created a lot of smoke ( I was impressed) the other wheel held on the foot brake.

I am sure I have launched at 2000 rpm before.

Any suggestions or advice would be great.

Thanks Bonzo

PS the car has a Barry Grant 625 carb performance manifold and a better cam.
ignition is standard apart from petronix and 8mm spark plug wires.

your gonna need a differnt torque converter, somthing that will let the engine rev up to 3500 in gear and maybe a 3.55 or 3.80 gear with a track lock posi. Add a set of bolt on traction bars and have fun.

Do as Fastback said but I think a 3500 converter is a bit big. I would with like a 2500-3000 stall. Also get some drag radials too. 255 BFG's fit great and hook awesome.

Also the stuggle to rev might be an out of tune carb.
