.30 over 440

Victor intake with 850dp
1965 coronet 3500 race weight
4500 stall
4.56 gears with 28x10 slick
 
here's a wild guess

These type of questions are so subjective... Just a Wild A$$ Guess.... not much information to go on here... But "optimistically maybe" mid-11's 1/4 mile et's 112-115mph & 525-550hp "maybe", I've seen impressive builds go slower & make less power, I've also seen "not so" impressive builds go faster & make allot of HP too... Maybe it could be much better, depending on many different factors, altitude, what type suspension & shocks, how heavy are the wheels or other reciprocating weight/rotating mass {effecting power & rpm}, are the slicks new or old {& what compound}, what type/size fuel pump & size of fuel lines delivery system {where/how it's set}, what type ignition system {where/how it's set/applied} & type of fuel used {pump gas or racing fuels}, what other trans upgrades other than a 4500rpm stall speed converter... It's a pretty heavy 3500lb car, on a little tire/slick & lose converter... IMHFO as far as HP/TQ it really depends on how good the heads are actually ported, what flow at what lift etc., what thickness of head gasket for final compression & quench, what ratio/style rockers & what valve lash, what valve springs {are they all matched to the camshaft}, what size valves, what size headers & exhaust {optimistically, something in the neighborhood of 2.06-hp/per CFM of flow potential & tuned properly}, what jetting & accel. pumps/squirter's & what fuel pressures, what other carburetor & ignition &/or other tuning improvements, how well it's been built/assembled & what % of leak down tested/cylinder seal & if it's even properly tuned... Then also if the car can hook well &/or if the driver can perform well etc... it has some good potential to go faster maybe, depending on allot of factors... Just a good performance motor, a 4.56:1 rear gears, lose converter & slicks, in a stock chassis, maybe not enough information here to go on... GOOD LUCK there's a great site with some really good calculators to put all your numbers in & get a outline what it "could possibly make/do"..... www.WallaceRacing.com/Calculators.htm
 
Thanks guys, I've been stressing myself to.death about this. But the car is set up pretty good suspension wise with super stock springs and a snubber. It has a factory bore and stroke 383 with .528 mopar cam, street dominator intake with an 850dp headers and stock 65 unmported heads ran 12.51 at 104 so I figure the 440 will have a good bit more
