So I snagged a "roller ready" short block from a 1990 Bronco with low miles. I tapped the two holes for the spider and slid in an E-303 before putting on a pair of Edelbrock E-Street heads (with an lsx valve spring kit from Alex'S Parts).
I have a pushrod checker that goes from 6.125-7.50 and with it adjusted all the way down I still have the valves hitting the pistons. This is with the head gasket installed and the head torqued. I set the lash on the 1.6 roller rockers and went to hand crank it and felt it contact.
My question is I'm not sure if a shorter pushrod would fix it, because the cam would still lift it the same distance correct? I have read lots of threads with people using the E streets on 5.0s with all sorts of cam setups with no issues mentioned.
Any ideas on what's wrong?
