Re: pro gram mian caps
is there a reason every one uses pro gram main caps verses another brand? clearance, strength,ect. I droped engine off at machine shop and he will be given me a call in day or so to talk about build and was gonna suggest these but didn't know the reason behind it. didn't want to sound like a ass trying to tell someone there job unless there was a purpose.
thanks
The bottom line here is it is your engine. You build it the way you wish.
The reason people use the Pro-Gram is they are 4 bolt as opposed to a 2 bolt and they offer "Splayed" outer bolts. That is suppose to offer more strength along with an "Air Gap" design. If your builder does not set up the registers correctly and the outer bolt Air Gap then you might as well have any other type of cap. Give these directions to your builder and pay attention to the order of operation for drilling the outer splayed bolts and the air gap specs for those outer holes.
<Pro-Gram Directions> I have seen these installed as a regular main cap and no air gap(mistake) and they walk when not installed correctly.
Note. You will have an issue with your oil dipstick tube fitting with these main caps installed so give him your oil tube and dipstick so he can fit it after the caps are installed it is a bitch to do when the engine is in the truck and you have limited room and an installed oil pan in your way. (I cut the oil tube to fit and the stick goes right past the cap when it is cut down and fitted). Also there is a rear cap available and is very expensive (it has the oil pump provision in it) most skip that but again it is up to you.
LMK if the link above is working for everyone.
