CENTER LINK DIMENSIONS, WHICH ONE DO YOU NEED?

Every build is different and there is no guarantee that what works on one car will be right for another. Its important to set your steering sector arm and idle arm exactly parallel with a center link that matches that requirement.

SPARK PLUG HEAT RANGING

I have had good success with the NGK spark plugs running my builds that use vortec heads. Here's what I have learned about finding the ideal heat range. The crate 602 likes the #8 due to it's limited compression. In a 10 to1 compression build the #9 was perfect and when I have run more than 11 to 1 compression, the #10 plug worked well. Remember, for NGK plugs ranging is higher number = cooler plug!
