What will it run with new convertor? Guess

What rpm are you shifting at? With that cam and heads I would think you should be shifting around 6500 or more. My magnum 5.2 has 210/[email protected] cam an ported magnum heads ([email protected]) and I shift it at 6200. That's where I had my best mph.

Up until last time I was shifting by ear...NO TACH
Last run 5200 rpm..
What all of y'all think I should shift at?

Hey no problem, no offense takin by me. I have only ever run 1/8th mile, so the 1/4 mile numbers I don't think about as much. I do think the convertor is going to help quite a bit, I am guessing is it ends up 60 footing about 1.8 or so and running 8:90 or so, at about 78 MPH.... not sure what 1/4 mile would be like.

No offense here...My car is a dog in 1/8 mile,,,at least it was !!

Bummer...

Maybe next weekend we can take both cars.

Might see if my Dad wants to go and throw mine on his trailer if he's in town.

Okay ..why you need a trailer..lol

Got a little done before the rained out race...
Removed the front sway bar ,fixed a vacuum leak to brake booster (got the correct hose instead of tie strapped hose on ends)
Installed a catch can that tech let me slid on for the radiator.
Fine tuned carb and nothing else....will re jet later. (running rich)
I just bent on seeing what difference the convertor does to my time !!!
Oh,I have practiced some 2000 foot brake launchs and what a difference I am right at 4000 rpm out of hole after tire spin ....60ft times will drop.
Is the weekend yet?Can not wait.....:burnout:
