thorcontr What's the problem?
It will not look right unless you add a set of 58mm TWM 's on the top. KCR has built a few, He would be the one to ask. I know there is a close cam to rod or crank thrown that needs to be check. Who's block, crank and rods are you going with?? IMO the only thing I am carefull with on any stroker is real good
oil pressure, like 60-75 psi at 2,500 rpm and limit the RPM's to 6,200 with max at 6,500rpm. That's alot of mass you are spinning. Barry R. sells a nice stroker kit for what you want. They will balance it for another couple hundred dollars. I installed a 482 kit in my Shelby block and everything worked out fine on clearances. You just have to stretch the rod bolts with a gauge and cut the ring for the pistons. What cam are you looking at. KCR sells some great custom hydro rollers. I have a small one in my 482 and will do the same in my 498 bigger motor with your TWM 58mm on it. I wouldn't over build the motor. There are other guys on the forum that will tell you that bigger and badder is not better in the long run.
10.5 compression and a good set of ported and polished heads will give you more power than you may want. My 482 torque motor is a handful. Your 527 is even more.
Tell us about gears for the rearend,trans, and power you are looking for? This will help fill in the blanks. 600 HP and torque is a safe limit for any cobra, after this, if not very careful is like playing with a loaded gun.
Hope to hear more on this build. What block are you going with? Rick Lake
