I'm going to get "Roasted " for this I know !! 400 thoughts ?

Update: I spoke to Engle Cams this morning about the specs on my old 383 cam .
Was told its a old solid cam (I knew it was a solid) with the 112 he said maybe a blower motor- at one time it did apparently have a blower on the engine.
lift is .515 exhaust (342x1.5)
,495 intake (330x1.5)
was told its going to have low cranking cyl pressure

I'm tempted to use it ..... or should i pony up and get the Thumper cam ?
