I currently have a 383 lt1 with all the bolt-on’s minus a cat-back, a CC306 camshaft 1.6RR’s and a PCMforless mail order tune that kills the plugs and the O2’s about once every two weeks. I also have a TH350. I just bought some AFR 190’s competition port heads that have been hand cleaned and a stock but port matched intake with a 58mm BBK TB, also a 3400 stall converter. I am having second guesses about the cam I purchased. It is the Comp Cams 07-468-8 cam. It has a lift of .584 intake and .579 exhaust the lobe separation is 113 and the duration @ .50 is 242 intake and 248 exhaust. Is this a good combo? Is the cam the wrong size? Is their something I can do to make more horsepower? Maybe a custom cam? The goals that I want for the car is to make around 400-420 rwhp and about the same amount of torque. As far a ET goes I want to run mid to high 11's on motor and in the 10's on a 150 shot. Help is appreciated. This is a street car but not a daily driver. I do take it to the track often. Help is appreciated.

-Thanks

 

the combo you described should easily meet your goals...I was also considering the XFI468 for my 396. The cam should make good power and still have decent street manners. I would expect mid 11's NA and easy 10's on the jug

 

that XFI cam will be a better cam than the cc306 in overall HP. I have one of the XFI468 in a stock bottem end with P&P,milled stock heads, stock pistons/rods,1.6rr,accel ign. 52mm TB, LT's 3in X w/bullets dumped, custom tune 4L65 w/3600 stall. I dyno it last week at 384HP 381TQ N/A 544HP 571TQ N20(175 shot wet) I dont remember the rpms at the moment(I can find out). I havent gotten a chance to hit the track yet and prob wont till next year. B/C i blew a head gasket friday night.

 

you should hit 400 with no problems. I have a similar setup and hit the 400 mark with a wayvsmaller cam

 

If I do decide to go with a custom grind. Who would you guys recommend?
