what is the max speed a LSP can achieve with the endorsement?

is there a endorsement for any extra gross weight.......its 1320 can you get say 1450?

I'm not quite sure what you are asking but LSA have a maximum airspeed (Vh) of 120 knots CAS in level flight, max continuous power, standard conditions and the max takeoff weight allowed for LSA is 1320 and 1430 for seaplanes. There is an endorsement for LSP that's needed to fly a LSA that has a Vh greater then 87 knots CAS. There is no endorsement to increase the weight of anything LSA, it's 1320 MTOW and 1430 MTOW period.

so does the endorsement for Vh greater than 87 knots still cap you at the 120 knots?

i guess im trying to ask, is there is no LSA legally capable of speeds over 120 knots constant level flight?

The cap for 120 knots is a ASTM design standard for ALL LSA aircraft. Do some go faster? Absolutely, mine does but not by much. If you want to go fast LSA is not the aircraft for you.

I had just viewed a advertisment of a guy selling a LSA and posted it cruised at 125 knots and it had me wondering

The 120 kts limit is an aircraft design spec, not an operating limitation. Vh (horizontal speed) is defined under very specific conditions (level flight, sea level, 29.92 in Hg, 15 C, zero relative humidity, max continuous power, CAS). You can cruise at higher indicated airspeed, at altitude under non-standard atmospheric conditions. You can also claim anything you want when you're advertising a plane for sale. If it really does perform at 125 kt cruise under the very restrictive conditions by which Vh is defined, then it's not an LSA!

Just for clarification for the OP, it's light sport aircraft and Sport pilot certificate.

As long as you have a Sport Pilot certificate and are flying a legal light sport aircraft, your privileges and limitations are as described here:

If specs for that aircraft is 140 knots, how does it qualify LSA?

Make sure you know exactly what spec you're talking about. The 120 kt CAS limitation applies specifically to Vh. The Vne spec (i.e., redline), for example, can be 140 kts, or 150 kts, or whatever - neither ASTM nor FAA rules specify that.
