Small Block Chrysler Racer Brown camshafts

Back in the late 60s/early 70s, we ran a lot of wild or non compatible combinations on the street because we basically didn't know any better. I guess with age comes wisdom, but I won't swear to that! LMAO

Lol. How true. I ran a .590 solid lifter cam back in the 1970’s on the street. then in 2008 when I switched back to small blocks my first 9.80 engine had a .520 racer brown cam in it.
 
I like to think I know stuff about cams but I guarantee Jim knows more. I took the plunge and had him custom grind the hyd roller for the 5.9L in my Duster, when he sent me the specs I had that little voice in my head saying "what if this was different, what if that was different" but I trusted him and sure enough it runs (and sounds) like a friggin beast, wouldn't change a thing.

To the OP, you could call Jim and get his recommendation on what kind of combo that cam would run best in.
 
I guess I'm not allowed to reply to the reasoning of this thread where it was mentioned of the racer brown cam being for sale with the price posted. I inquired. My bad
 
I had a 340, back in my racing days built with 13:1 compression with flat top pistons. With that much compression, it required a dual stage ignition; a button to turn the engine over, then turn in the ignition. I ran 10.70s in the 1/4.

What's with all the question marks?

You said you had a 340 with flat tops and 13:1 compression.

Either you milled the crap out of the heads and block to do it or it wasn’t a 340.

My 340 is 12:1 (measured) and the pistons are .048 out of the deck and IIRC the dome is .140 tall. I mean the deck of the piston is .048 out of the hole.

With a 3.313 stroke its very difficult to get that much compression with a flat top.

So I was questioning either your actual compression ratio or your displacement.
 
They were custom pistons that had the wrist pin holes drilled. The block was the original one.
 
Anyone know who ground the .620 - 324 solid flat tappet for Mopar performance?
I'm not sure how long it's been around but I know back in the mid 90s I wanted one but never had enough engine to use it. Anyways I'm buying one and would love to hear some history of it

Racer Brown arguably has the best grinds for Chrysler engines. A lot of these younger guys probably don't know that Racer Brown supplied ALL the camshafts for Chrysler back when it was Direct Connection. All those grinds are still available through Racer Brown.

I loved the old 590-312 Mopar purple shaft. My home ported J headed 340 loved it too. 11.02 @ 123. flat top pistons and 3150 lbs Duster
