Building a 340 engine

I like the howards or a Lunati Voodoo also
but he owns a cam that is slightly larger than the 340 HP cam at .050
slightly shorter exhaust, but that's good a as he has headers
so
IMHO not worth spending money on a cam change unless he could do a swap/ exchange
I do not like comp but he has what he has and it will work with the rest of his parts and heavy vehicle
cheers
