what would a 302 with a racing intake 850 cfm deomon carb a 447/447 lift and a260/260 dur with 1.7 rockers stock ported heads a storker kit hookr super comps and 4.56 gears int he rear end what numkbers will that make in hp and torque if i had the 1.7 rockers will i need to have diffrent push rods so i dont cram a valve in to a piston

 

Don't know what you mean by a racing intake, but any one you use with that cam should be a dual plane. Weiand Stealth is a good one. The 850 cfm carb is too big for a 302. A carb between 500 and 670 cfm's will work fine, depending on what you want out of it. The 4.56 gears are pretty steep for a daily driver. 4.11 at the most with an overdrive transmission, or 3.50 or so without an overdrive will give you better mileage plus good performance. The 1.7 rockers will be just fine with that cam. It isn't a very high lift cam.

 

Not only is an 850 demon too big for a 302, (or a 347 for that matter) a 650 double pumper is usually more than enough. I would not even waste the money to put a set of ported stock heads on a stroker motor. Even if you ported them yourself, by the time you bought good valves, springs, good valve job, etc. you would be better off with a set of aftermarket heads. If it is a matter of horsepower vs money, you would be better off with a 302 w/ good heads than a 347 with stock heads. As for the cam I would look for something with more lift, usually on a 302 you won't have any valve interference issues until you go over .500" lift. In my opinion the 1.7 rockers on a small cam is a more of a "band-aid" fix. As for the intake and gears that all depends on what you are putting the motor in, what trans. you are using, along with their intended use.

 

it is manily for strip use not that much a dallily driver it has 3.75 stock and it has an aod trands but the 850 demon powers that car great it studers a lil be cuz the intake kicks in a 3500 its a hurican but pro products and if i had a 6 something lift on my cam and i had 1.7 what woudl i be lookin at for hp whise adn torque
