The 448 is a BB (.020 400 block with a 3.75 stroke)

It pulls quite strongly to 5800 and a is little flat after that.



Never thought about that.

Bummer I like to turn mine to about 6k some too 6500.



If you like to turn it up to 6500.... I would see if
you CAN advance the cam.. IF you have the piston to
valve clearance... if so then I would advance it
about 4*-6*... that moves the whole torque and HP
range lower in the rpm's... gives you more effective
stroke so it would up the cyl pressure... I have my
cam advanced 6* in the race car but I have the cam
in my street rod straight up but thats a tight 105
LSA cam and I dont want the added torque because
it would raise the stall point higher than I need
