Hi guys , im on a extremely poor budget for my 318 fury :) , bought a new 9905 600cfm edelbrock with an adaptor to convert the 2bbl to a 4bbl , i have tons of magnum manifolds laying around , i want to clean and port the intak and heads...but a big BUT ***** i want to order a cam , AND its like 700$ canadian for a cam kit , is there any cheaper way to have a good 450-480ishh cam and to run with a stockishh 318 and not spend a ton on springs -retainers / , special pushrods bla bla bla , of you guys have a cheap recipe and part numbers i would really appreciate it , i saved a bit but its for the whole car , i cant spend 1 or 2k on the 318 to updrage it neither : * 1st LA for me , always ran rollerized magnums
1.7 rockers and some springs.
Who makes them.

Custom cam, engle has the old masters for Hughes. I had them grind one up years ago for a 318 truck motor 'smog'
.479 208/216 112 or 114
'cant remember' atm.
Its here in a thread of mine somewhere.
Get someone to purchase and mail it, or is the tax/customs fees what gets steep?
Seems like Canada is a costly place to export to... robbing the citizens
