Specs: what do I have and what do I need?

VegasJetta said

Hey guys, I have a 273 thats been rebuilt, all stock.
What lift and duration cam came stock in the 273?
what would a good performance upgrade be?
what carb/intake setup would go well for everyday street use, and give a little more power?

I am new to this again (its been 10 years since my last Mopar) and all the old Mopar info I had in my head has been pushed out and replaced.

help!

273 2 bbl cam was.395" on the intake
.405" on the exhaust
the installed spring hight was 1 11/16"
valve spring pressure @ 1 5/16" was 145 lbs
240 degrees duration


4 bbl was a solid lifter cam, I'm not sure about the 2bbl cam but I think it was too.
273 4bbl cam was .415" on the inake
.425" on the exhaust
the installed spring hight was the same
valve spring pressure @ 1 5/16 was 177 lbs
duration ???
I dont know the timing stats but my 273 4bbl was a terror...it revved and made alot of power!
