whats your thoughts on street stall speeds 727 info inside

727 68 340 x head motor 10.5 to 1
750 eddy
elc ing
mild purple shaft cam
stock hop manifolds
stock intake i may change that to some thing close not to crazy
pretty much a stock motor was fresh last year when i got car
i have no details on motor just going from general knowledge of how the car runs

8 3/4 323

i drive this car all over high ways streets race every now and again
right now the car over powers the stock stall so that needs to go

i may spray the car with 100 125 once in a while
not sure if i need a balloon plate or not for that littel bit

im thinking a 2200 2500 should be just right
whats your input

any good makers any one recommends ive had bad problems with getting screwed by the high dollar places having them built and there 3500 away from what i told them to build not once twice but yes 3 times i sent it back they never got it right and guy wanted car so dont know if he changed it or they fixed it but dont by a EDGE racing converter
