RE: cam and carb combo
Hold on a second, What block do yo have? The B-303 is a roller and the one you listed from Summit is a flat tappet. You need to come up with a plan on how you realy want this thing to perform.
Again what heads are we talking about (if they are stock castings it is very unlikely they will flow 215)

definetely need to step the cam up for the 351 look at a comp cam or like a trickflow stage 2
...thats what i have in my 306 and it would work good for you.and a 750 carb is too big look for something around a 650 thats plenty for what your doing with it it sounds like.

RE: cam and carb combo
if you dont wanna buy my carb ([8D][8D][8D][8D] ) may i STRONGLY suggest either a proform or a quickfuel. i've come to learn that having TOTAL adjustability is worth its weight in gold.
oh yeah, and your motor is setup for a flat tappet cam - check out the crane Z series. they have new lobe profiles with some modern technology going into them (the first new flat tappet grinds to be made in quite awhile from what i have seen)

RE: cam and carb combo
ok i have a question here the cam specs that i have been told would be good for me are. 230 intake, 240 exhaust with an intake centerline of 104-106. Now i was told by a buddy that my intake centerline is too low and it should be upwards of 114-116. Now i may have heard the guy over the phone wrong but what do you guys think. That cam with a 750cfm vacume secondary demon carb high rise duel plane edelbrock intake mani and some 205cc heads should work nicely and if i mill them bump up my comp a scoch.Now i also have another question i was lookin at another set of heads and i couldnt find the CC for the life of me all i got was the CFM. At .500 lift it flow 218 at .400 it flow 196. Would there be any way to figure out the flow at .300 , .200 , .100?im tryin to find out how nice these heads are.

How can you recommend parts that work for your "306" to go on a 351. 650 on a 351 is too small, it may work for your little 306 on it would choke a 351. Besides you shoud not make a recommendation for a cab not knowing whatthe engine/trans/chassis combo is. This goes for cam aswell.

hey man i have been around fords my whole life even had a big block highboy before i was 16 i totally restored,had too many ford trucks and cars . have built 2wd,4wd cars trucks, big blocks,small blocks,big heads,big cams small cams, big carbs,little carbs,dual carbs,70 ss chevelle,70 chevy truck shortbox.F... y.. man
a 650 will be good for a daily driver and the occasional track time , i ran some of my big blocks with 650 and i had better luck with these that the 750 for a dd and toy.along with the cam it is not to small for a mild 351.
i know a guy with a 408 with a small crane cam ,stock ported heads,rpm2,longtubes that makes 444 rwhp and almost 500 rwtq
u sound like a smart guy but it looked like it was just some mods i did not realize all he was doing to the car

RE: cam and carb combo
if you have a custom cam designed flow aspects at each degree on the head won't be as important as duration can be altered to compensate for it...I'd look into getting a custom cam to maximize your potential
