XE268 and XE274 cams

Well I have thought about xe284 cam but way Ken talked with this going in my 83 D150 shortbed He thought i needed to step down to the 274 or 275HL!Just gonna be mostly street duty!He said he has used the xe274 in alot of sb strokers and performs well but I came up with the xe275hl cam and he liked the idea so we agreed on it!If I dont like the cam I am gonna switch to a Voodoo cam!Thought about solid cam but dont think I want to have to adjust valve lash alot!Plan on driving it as much as i can!Almost everything in the motor and heads is from Comp Cams so i wanted the cam to be Comp!The heads have double springs matched for the cam and is getting valve job!How many rpms does the cam come down in stroker?
