i am piecing together my 351w and i was told that the cam i have is not going to be sufficient. the specs are lift:472/496 and the duration is 214/224. i have a typhoon intake. I plan on using 30#injectors and i am hoping for afr 185's. Will this cam match well with all this or should i change the cam, etc? thanks for any suggestions I will getting my fuel injectors/mass air sensor soon hopefully. I am deployed for two months and i am saving back the money for my heads also. Help asap

 

It is an old outdated generic grind like the 6250a312 and others like blue racer and Edelbrock. Would be OK with stock heads and small 4V carb.

With 185s I'd go with a hydraulic roller conversion.

I know its not the $90 answer you wanted.

 

So what kind of lift and duration am i looking for with the combination i am planning on doing?

 

I don't know, it's your car.
You probably want around .512" lift and 224-230 duration @ .050
Since you are EFI, 114* lobe centers would be a good idea.

This would be a hydraulic roller grind.
Go to comps online catalog and pick the lobes you want and have a custom grind made.

Buy your heads first and see how much lift they can take.
