Well, can i still get a 30-60 min run time with lead acid batteries and them alone are $100-$200 each and also, anyone have any good plans for a shifter or racing kart chassis? One more thing is it still possible to go 30-40 MPH with keeping everything under 650?

This guy made one and only used 24 so... i would only need like 16...

Sure but they only hold 15AH and cost 24 bucks a pop..
making your single set 360 dollars worth and you still would NOT reach an hour of driving time (half an hour maybe)
So still... 30Ah is what you'd be aiming for (double that up... aaaand hoorray you're back at 720 bucks for just battery cells!)
Why a shifter chassis? the main difference is front brakes.. a pair of used front brakes costs you ~700 ; 400+ used mostly...
not a smart choice if you're on a budget.
Pick a 100cc kart chassis instead they're plenty and easy to get hold of for cheaper than you'd be able to make one yourself.
if you're on a budget going electric doesn't make much sense..
staying under 1.5k is difficult if you want mileage and power
staying under 1k is tricky and requires many used parts you got for cheap
staying under 650... nearly impossible!
You can push a small brushed my1020 / zy1020 (48V 1000W) (~
100 bucks) to these kinds of speed if you're patient (it's not powerfull enough for good acceleration and speed.. pick one)
it's mechanical power mind you it draws up to 30Amps IIRC..
say 25 for the full non stalling power.. in an hour that'd be 25Ah (see?)
and it's just a small 1kW motor just barely enough to get to the speeds you want.
add ~50 bucks for a decent controller and just lead acid cells (80 bucks for 30Ah)
and you're at 500 bucks for the electric power (incl some wiring and fuses)
sprockets and chain, chassis and a throttle are going to set you back more than 150 I'm afraid.
So we already cracked your 650 limit!
What you'd really want is a ME0909 instead
(the brushed 5kW variant of the motor used by the instructables guy since it's cheaper)
costing
400 bucks a matching controller sets you back about 70-100 dollars
and you'd want 60Ah cells at least... (130 a piece)
and you end up @ about 1100 plus chassis, mechanical drivetrain and throttle etc..
And all that babble to say one thing:
listen to mckutzy!
if you want to stay below 650... get a gasoline engine,
a predator if you are an american, any gx200 clone if you're not.
120'ish dollars for the engine, 80 for a torque converter
and you have 450 bucks left to find a chassis with brakes and wheels that you can mount it to.
