| Post subject: | Supercharger Camshafts? |
I am thinking of possibly doing a supercharger system from the Supercharger Store and they call for a 114* center line on the camshaft. I have a CompCams 264S with a 110* center line would it have a favorable outcome or should I sell the 264 and look for a new cam? Anyone know of a cam with 114* centerline? What other cam specs would be good for a supercharged slant? Michael |

The Comp 264 is pretty mild and should work fine. The wider 114° lobe separation would be more important with a longer duration cam. Personally I would get a longer duration cam with a wider lobe separation for increased performance. Oregon Cam Grinding has many profiles to choose from that can be ground on the desired lobe center and all cost less than a new Comp Cam. |

Given that NA nts like 2-4 deg ss LSA than most V8s, I would say 110 might be fine, esp with the shorter duration. You could make more power with a longer dur cam, but what are you after here - racecar, street/strip, cruiser?? Lou |

The car is a 64 valiant with a 225, planing on 9.1 compression, .060 over pistons, and oversized valves. It is going to be a street car that will see the track offten. It has A/C and will be running an A904. and the supercharger will be the P1SC. |

How fast do you want it to go? Pump gas or race gas? How much boost will you run? Carb or EFI? Timing retard system? Lou |

Well fast is up to everybodys interpretaion but I am tiered of being left behind by silly imports and preppy mustangs. I know I may be asking alot but hopefully 300-350 hp. This will have to be a street car. It will be EFI and it will have to be pump gas, no more than 93. I do plan to run Methanol Injection so I may not need to us any retarding but if I do I can use the MSD-6BTM that I can get my hands on if it is needed. I figure start with 7pound pulley and work my way to 14 if its needed. And Maybe I could try to break a record someday. |

OK, that is helpful. Since you are spending some coin, I HIGHLY recommend getting a good cylinder head done. Mike Jeffrey can make you a killer head for way less than the SC or the EFI, and it will make all the difference. 300 HP should be no problem with 7lbs of boost, a good head, EFI, and that cam. You might go a little bigger on the cam. I would think something like a 280/280 Erson (228 @ 0.050" or so) and 110 or 112 LSA would work great on a street/strip blower car with true 9:1 comp. Lou |
