Well after alot of research, I have decided to go with a pair of T76's w/BB for my 383 ci motor w/AFR225 heads. Question is what size A/R will be ideal for a car that is street/strip (60/40). I was thinking .96 but would .81 be a better choice?
Thanks.

For A/Rs I could dance around the question all day and suggest stuff that I think will work but for your car I would honestly give one of the sales guys at Turbonetics a call and they can spec out an A/R even if its custom for you to perfectly suite your setup. Try Ed or Steve at 805-581-0333 and they can get you set up.

i would go the .81 a/r's
would spool 300- 500 rpm quicker,
make bit more torque down low, for street application

we have 358 cubes, with twin gtk 1000 ( 76mm bb's )
.81 a/r was ok, had to spin the engine harder to make the power...
.68a/r would be ok, if i kept rpm down.

all depends on rpm range..

I'd like to see what this set-up made also. It sounds like a badass ride!!
