I have a home built twin turbo setup. 306 C.I. 8.25 to 1 comp, t60's @ about 15-16psi boost, flipped MAC shorties, H2O & alky for intercooling. I was running 42lbs injectors till I popped a head gasket, now I am installing 60's. I have been running a 93 cobra intake, but might try my carb victor jr. converted to EFI, just for kicks. But now here is my question, I have 3 different cams to choose from. The first is the stock 1990 5.0 cam, I do not have any specs on it but I know that overlap would be the smallest of the three. Cam #2 is a Crane cam for using the 93 cobra 1.7 rockers. It has about 56 degrees of overlap its ground with 112 lobe seperation. The duration is intake @ 214 and exhaust @ 220. Cam #3 is a Anderson B-4 supercharger cam. It has about 66 degrees of overlap and ground with 112 lobe seperation. The duration is intake @ 224 and exhaust @ 232. Cams #2 & #3 are both ground on the same center lines 107 for the intake and 117 for the exhaust. That puts them both @ 5 degrees advanced when installed straight up. Any help as to what would be the better cam to run would be great. And also I would not be opposed to running any cam advanced to help out running better.

 

im not sure about the cams u have but some people on here run f-cams and tfs stage 1 and 2 cams..if it was me i would try the anderson B-4.. they say its like the stage 2 tfs cam..

You will make more power with the bigger cam.
