Driveability is great. Occasionally I'll have a little tip in hesitation off idle, but it's not bad. I can drive it in 6th down at 1000-1500 rpm without any real bucking...

Here's the before and after graph at the SAME place on the same dyno...

You can see where the retard kicks in and the resulting dip in A/F and power...

Pushrods are TSP stock length chromoly... they look like the TFS pushrods that I had for my mustang... I'm willing to bet they're made by comp.

Valvesprings are PRC duals sourced from TSP.

So, if I understand you correctly, you made 50 RWHP on the cam swap only? If so, very nice! It sounded like you already had the headers and other stuff on when you pulled the 375 RWHP.
Inquiring minds want to know.
Thanks.
