I am getting ready to have my motor built. My tuner is suggesting i go with the 5.3 stroker based on the Boss block. Just wondering what you guys think?..Shall i just stay with a 5.0 cobra block stroker or go for it with the Boss ?..I'am not sure what i am getting into i guess so looking for some advise...pros/cons This a weekend driver with very little track. I also run the 2.3 whipple. Thanks for your comments!
