I would go with these guys they can save you $$ by regrinding your cam to about any profile you want. http://deltacam.com/ Give them a call,many positive reviews on the Main board,the pricey part may be the Johnson adjustable lifters,maybe they have a solution.
When flatheads and Y blocks are spoken of, good parts and cheap prices are not used at the same time. I have had both, well built, (expensive), and the feeling of personal satisfaction is wonderful. The good strokes from perfect strangers are always welcome, and seem to come at every stop. Do your home work, spend some bucks, keep it clean on ***embly, use the right oil, and GRIN!
Not trying to be cheap, but if there is a deal to be had we'd like to find it. Every one's price so far is within dollars of each other which makes me wonder why? Don't expect SBC prices but it shouldn't be as high as it is, its a cam, crank etc... not crazy so far. Believe me we'll be GRINNING!
