really? there are actually just like the comp cams 270. the cams i'd get would have 233/237 @.050. do you think yhis would work without any piston work until i get a new block? How do you degree the cams? thanks

If they are just like comp 270s I know they will fit for shure you wont have to fly cut a damn thing. You will need them degreed in order to work as it will be close. Also with those cams you will needstronger valve springs.The way you check piston to valve clearance is by installing a test spring in the number one cylinder intakevalveplace the piston at top dead center and place push down on the spring or roll the cam over(no chain on it)with the lobe at max lift and push down on the valve if there isnt much room you may need to use a dial indicator but like with my cams it was so much clearance that there was no need for precise measurement. Degreeing is a whole different story. That is complicated and takes alot of time unless you have adjustable cam gears. here is a few pics of us degreeing mine notice the dial indicator on cylinder 1 in the second pic. If you want contact "NeverEnough" over on modulardepot forums. He did my cams for me and it was well worth it because there is a ton of specialty tools needed, like spring compressor, solid lifter, degree wheel, and other handy odd tools, Im shure he would help. He installs a ton of modular cams and in his own personal car had the comp 270's until he went to 4v. So I know for shure they will work.

One more thing....degreeing the cams can add alot of power because it perfectly balances both banks of cilinders. Just degreeing stock cams can add up to 15 hp. My left bank was off 4 degrees and the right was off 2.5 degrees. So there was a 1.5 degree difference between both of them not to mention the 4 degrees off they were from the 110 centerline they needed to be set at.....so thats power just left on the table. I promise you you wont regret taking the time to do it right. You would be suprised how many people just line up the cam gear dots and chain lengths and run there cams and by some miracle they get away with it.....however some do not. Always degree your cams.

Ain't that the truth! Some lucky SOB's out there!!! Always degree the cams if you can.
