That Isky camHL hyd (not) us 50 year old chevy profie Two Strikes and expensive we have much better springs available today We used to sell a lot of Megacams as they will overrev without complaint you can do a lot better than that long duration low lift profile
Wyrmrider, this was a recommendation by my machinest a GM guy because of the gearing and compression. What would you recommend. I have this one sitting on the shelf.
The 272@.004 duration on that summit cam pencils out to need about 9.7 compression ratio, same as 264 @.006 problem is it has no lift or area under the curve what did you figure your compression is now that you have your heads? did you post your deck clerance etc? if you do have around 9.7 true CR check out a 264 lunati or Howards if not post back you can get a fatter lobe down to 256 if your compression is lower like 9:1
If the question is for me, My CR pencils out to be around 9.6-1i have the heads, have not torn the block apart. Was wanting to find the cam to run with my CR ahead of time then shelve it until needed.
Rest assured, no matter what you choose, someone won’t like it and will tell you how poor of a choice it is. Just remember, the only one who has to like it is........ you.
