i make up a long feeler gage out of cardboard a bout 060 thick or abit thicker and turn it thru by have i do one hole at a time with no rings on the pistons if every thing you have clears the rods if scat could be the they used a short bolt and this will give you more room so you do not have to nip the bolt heads you with a thru bolt rod want to TQ them up so you know the end of the bolt will clear the oil pan rail to this is what we have to do to get them big cranks to swing thru

Thanks Pat, I'll try the cardboard. I was surprised nothing hit, do the rods you use have the edge chamfered where you're doing the clearancing in the pictures. I wanted to take pictures but my camera battery is dead. Maybe tomorrow.

Next question is about push-rod length. I consulted this link that shows the checker I bought from Summit.

http://www.thedirtforum.com/pushrodlengths.htm

From this I got my max lift of .48 subtracted from .60 is .12, divided by 3 gives me .04 gap. With the preload adjustment of .021 My total is .061" total.

So I measured with the lifter fully down but not compressed and I have a gap between the pushrod and the measuring tool of .039. So I guess that means my pushrods are .039" too short??? I'll have to measure the total length and go buy some longer ones tomorrow then do I??? I have comp roller rockers and AFR heads if that makes any difference. Also am I doing this right???


Thanks,
Sean
