I have a mild bb stroker but am looking to get into the mid 10's. Can an 18 spline handle the abuse? What mods to the trans would you guys recommend for dual duty? Thanks
1; Yes
2; Face plating
2b; Dual duty can be a PIA at a high power level. Highly adjustable shocks on a 4 corners would be my start. Disconnecting and reconnecting front and rear sway bars is a PIA after a while but good for the dual duty car. Sway bars in the street are a really great addition IMO. Maybe not so much for the drag strip.....
I myself would avoid the old “Hot Rod/Racer June bug stance” in the street unless you like it. Street driven cars react and feel so much nicer when there closer to a stock or level stance. A few friends of mine also have two sets of tires for the track and street. IDK if that is OK with your wallet. Purchasing 8 wheels and tires for one car is a lot of money.
