Warning: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in ..../includes/class_bbcode.php on line 2958 Rebuilt engine no compression
Has anyone ever experienced a no compression issue with a rebuilt engine? I have a 304 bored to 310, rebuilt heads,, edelbrock performer intake, cloyes double roller timing chain installed straight up, comp cams 252 cam kit, holley ta 470...I cranked engine over repeatedly and no luck starting, didn't even sound like it wanted to. I thought dizzy was off 180, but made no difference. I notice by pulling #1 plug out to verify tdc I wouldn't get any pressure on my finger. I only noticed some suction on down stroke. I put compression tester on and read zero with throttle wide open.
I thought maybe comp pushrods could be too long, lifters are pumped up, cam timing off? I know I installed can dot to dot on chain sprockets with zero timing. Maybe. Sprockets were marked wrong....it's just very frustrating to sink all this time and money into something like this only to have a major issue. Any advice would be appreciated. Of all the engines I've built, never once had an issue like this.
