BrownStainRacing. I am well aware that you are no fan of any of the dyno cam products. Those 265 turd cams if I remember correctly. No argument from me that the Isky cams sold by small engines cams inc. are probably better. I don't know, I have never run one, but anything connected to ISKY carries a lot of weight with me. On the other hand, for a meseely $62 the ready to run CS grind, with it's low duration ( 225 & 236 ) and .265" lift has worked out pretty good for me. It's in a very heavy ( 340 lb. empty ) 2 seater and pulls VERY good. NO clearance problem whatsoever. You stated that you will NEVER install a billet rod again in a
224 predator. Really. I watched the Grey Goat Garage video prior to doing mine and while it took me longer than I expected, I feel like I could do a second one in half the time of the 1st. I don't know if I would be comfortable grinding away on the center of the cam, but having a feel for where, and about how much on the block wouldn't take nearly as long. I like to get rid of the governors, and. seeing how it's grandchildren driving, feel a lot better with the billet parts inside.
Jus so we stay on the same page, all my builds get ONLY Dyno Cams valve train parts, except for the camshaft. Most get pistons from Dyno Cams.
The CS grind is not a bad cam, it's more of a mid to high range cam. Jus like MOST of the Dyno Cams for track racing.
Look at the specs
Add the intake close and intake open points together, then add 180.
Thats the advertised duration (usally.004"-.006") of the camshaft for the intake side.
Now subtract the .050" duration from the advertised duration and that number is what makes a much better cam in a broader rpm range. The lower the number, the more power you will get out of the cam in the WHOLE rpm range, not jus mid and high.
Heres the bp2 grind. Do the math compared to the CS grind, and you will see what a difference that number will be. The bp2 will bring the valves off seat and back on seat much quicker, making power come in much quicker, rev fast thur the mid and get to the high side of the range much faster, creating a broader, USABLE power range.
Even tho it has more .050" duration, it's a much better cam for the WHOLE rpm range.
People shy away from the bp2 cam because of the stock lift, but it works great for all types of terrain, not jus flat tracks, with tiny people, running small tires.

Here's a small ECCarbs cam, do the math, they are FAST aggressive ramped camshafts.
I don't run em because of the big spring pressures and work it takes to fit the springs correctly.
They make great power, it jus takes more money to set up the head.
But I'm sure you get what I'm trying to say.
Take care, always good to chat with you,
