6.980 pushrods for 289, Comp cam, Brodix ST 5.0 heads?

[rgsauger]

Hey guys! I sure do learn a ton here. Thanks!

Building a 65 Mustang for a buddy of mine. Putting the motor back together and had the Machine Shop do the short block. Comp XE 262 cam, comp 1.6 fiull roller rockers, brodix st5.0 heads, intake carb headers, ignition, blah blah blah. Put in some checking Springs today to check pushrod length and it surely seems for all the world like the proper length is 6.980. That seems a little bit long to me but the comp lifters are also a little shorter than my factory ones. The checking Springs only had literally about one to one and a half pounds of force so I'm quite confident that they were not depressing my lifters. Just wanting a sanity check that this does not sound crazy for a pushrod length. Thanks much.

I've moved this thread over to the Fox forums (temporarily) because I think these guys can help with your question. There is a permanent re-direct to this thread back in your home forum.

If you would like it moved back, just hit me up or another staff member.

I think this question will get more action in here.

It is awful quiet in here.

I went with 7.000" Manley pushrods. With about .025 - .030 lifter preload, they were perfect.
