89 Mustang Pushrod length question
Ok so I have a comp cam p/n 249-35-351-8, gt40x turbo swirl heads, crane 1.72 roller rockers and I need to know if the stock push rods are too long? The lift is .512" intake and exhaust, duration 270/276, with a 114 degree lobe seperation. I think the push rods are too long because the valves are not closing all the way to build proper compression. With 1.6 rockers there are no problems. Has anyone else ran into this problem before? If so, what size push rods are you using?
Thank you in advance.
