The key is they need to stay tight and that doesn't always happen.  If it moves, you are done

On my Mustang, I didn't like the front upwards bolt over 30 years ago and was able to fish a nut on the back through a seam on the top of the rail.  That one of course tightened solid sandwhiching the bracket and frame and the rear tightened nicely, so I put the remaining bolt in and history has been good to me

great build for a killer car.how did the oil pan do on the dyno?as for oil presure.i am trying to decide for my build between that pan and the wide pan they offer.

Oil pressure was steady on the dyno with the deep Canton pan and screen tray. I'll be using an accumulator in the car, just to be safe. I stayed away from the wide pan because it limits the available space for header primary tubes. Things are already tight in a Mustang compartment.

Not sure what you’re looking at in the fuel pump area, I went Magnafuel MP-4601.  So, adjustable bypass, 10AN in and out, and the volume I wanted, then an adjustable 4 port regulator at the engine, so far very pleased.

I already have an adjustable Aeromotive regulator, so just need to get a pump, which I haven't looked at yet. I'll probably go with size 10's also, just to know I won't be running out of fuel, along with a custom pickup to feed it.

Wicked pump gas engine.
Might need more gear? How tall are the slicks?
Congrats!

I have 28" slicks, and I don't want to go modifying my wheelwells, so likely stuck with that size, although I may be able to pick up a couple of inches if I relocate the rear. My Currie housing is narrowed 2" so I could try and keep things tucked in, and I have clearance with my springs with the backspacing on my rims, so that's not an issue. Currently have 4.30 gears, which puts me through the traps at 6500 with my current tires and combo. I may be able to keep that gearing with the goal of going through at 7500, but I'll just have to wait and see how it plays out.

I calculated 4.750 Stroke! Amazing what can be done with the cam missing. 

Very nice ! Killer combo and not huge cubic inch. I can attest to Blair helping on the dyno, we had several issues when he helped me to dyno my engine , that he didn't build but offered to let me dyno there and he helped me a lot with cousin Johnny!
