First....cam

this is a good grind....it will make some power....good gas and conservative timming...or it will detonate...start with 26 deg total and bump it 2 deg at a time till you find the sweet spot....

second....heads... they are fine...sounds like you got a good set...

third....card...850 double pumper is good for street and/or mild tract use and more strip and you'll need a bigger....personally I'd opt for a 950+cfm

fourth.....the strip dominator will work best with that cam but, for the most part I'd go with the dual plane if you going to do a lot of street driving....you'll gain some low-end torque but at the cost of upper HP....

fifth.....the hei you use will be fine...add a MSD or crane ignition box to compliment it....

rear suspension upgrade.....to help it stick
