Any updates on this build? Tuning changes net more for you or better track times?

 

I ran a 12.5@107 in my ECSB 5.3.

It had a flt lvl 4, fuddle 3600 converter
I put down 389rwhp/366 on a tr224 (110LSA) and some texas speed stage 2.5 heads milled to 57cc. I was using the stock truck intake as well.

Id sell the intake for a bigger cam and find a new tuner.

 

Big cam or sell those heads if you don't , those heads needs big air improvements

best of luck

 

Any updates?
