Hey guys. I have a 1967 GS400 completely stock. Wanted to give it some more power. im dint plan on racing it at the track, but would like a bad *** street car eventually. I'm thinking of starting with new cams, lifters, & torque converter. I would like to eventually drop a 455 in the car down the road. I've been looking at lunati voodoo cams. Particularly the one below:
Hydraulic. High performance street/strip cam for 400 cubic. Excellent camshaft for 455 c.i. in heavier type vehicles with 9:5 compression ratio, Use 2200-2400 stall speed converter with 3.42 gears. Cam has a very noticeable idle quality!
Advertised Duration (Int/Exh): 268/276
Duration @ .050 (Int/Exh): 227/233
Gross Valve Lift (Int/Exh): .505/.521
LSA/ICL: 110/106
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 1600-5800
Includes: Cam Kit
Part Number: 10960702LK
Will this work for what I'm going for, or should I go with something different like TA or Crawford?
Also what would be a good torque converter to go with this?
Thanks,
Josh

Hi Josh. I don't know what to tell you about the cam but, about the tourque converter.....Wire around the stator switch so that YOU control the switch pitch. That way you can have the higher stall speed whenever you want it (at low speeds). I think you can achive around 2500 rpm stall with the brakes on. Then let loose the brakes, shove the throttle to the floor and hang on. As speed increases, the variable pitch looses it's effect. The oil in the converter solidifies around 4700 rpm. So, your not going to have a runaway engine. Also, this costs almost nothing. You didn't mention it but, the carb. Sooner or later some guys are going to tell you to get an expensive carb. Usually a Holly. If you're going racing, it would be ok to start spending money on the fuel system. But the Q-jet that you have is an excellent carb. When set-up properly it is a great carb. And, you already have one, again, little cost. If you need more fuel, you might try cutting the divider out of the intake manifold. Thats been discussed on this site before. And with lower gears you'll probably need a bigger fuel pump. Remember, the most bang for the buck for acceleration is rear end gears. Of course there's the trade-off for street driving. Good luck and have fun with your Buick, they're a lot cooler than Chevys and stuff. Tom Barnes
