6.4 cam in a 5.7
 
was wondering if anyone has attempted this yet.....the new 4th gen hemi's share the same deck height as far as i can tell.....the 6.4 has some decent cam specs (close to what these crower cams spec at).....im really debating on trying this over the weekend...id just hate to have to put it all back together with the stock cam due to some unforseen clearance issue....according to the numbers ive been able to find i should have enough clearance....the reason for all this is im not to impressed with the results of the regrinds (crower,inertia,arrington,etc) for the price....i can get the 6.4 cam at the parts counter for 60 bucks!!!!!!
not sure about the springs but im pretty sure ill also need the pushrods...either way its all pretty cheap......so whats you guys opinion on all this?

I think the price you were quoted is wrong. Also, I belive you would need to change to the 6.1L valvesprings and pushrods.

price is right....looked it up myself......unsure about springs/pushrods....i have a couple sets of 6.1 springs/pushrods......even have a set of pac racing 6.1 springs.....i was under the impression the 6.1 parts were a no go....
