Main Bolts
Hi,
I'm trying to find the right main bolt kit for my upcoming 351w swap and I've encountered a suprisingly large selection of different options and don't know where I should go.
I know you need to replace the mount bolts each time, once they've been stretched they are useless to use again. Is the same true for the main bolts? Is this a 2-bolt main such as the one found at ARP 154-5003 - ARP Main Bolt Kits - Overview - SummitRacing.com or, does it require the full stud kit? What else will be an absolute necessity for my upcoming swap?
I want to do a quality job with the swap but haven't ever really tackled this project without knowledgeable assistance. If I go over budget too far my S.O. is gonna kill me.
As usual, thanks to the awesome folks here who help out the newbs!

Sorry, yes I shouldnt even need to touch the main bolts.. I'm showing off my maximum newb today.
I'm swapping an 84 351w with no oil pressure and signficant knock to an 85 351w that's got good compression and is running right. Just a straightforward swap, nothing fancy. Coming out of an 85 F-150 2wd into my 84 F-250 4x4, both 4spd manual transaxle.

The bolts that hold the engine to the mounts. I've always thought they needed to be replaced each time as they are torque to yield and once stretched they are no good to use again. I could just save myself some money if the consensus is that I'll be fine

The mount bolts had me a little bedazzled too. None of the bolts are torque to yield on a 351w. I think he's thinking of the newer engines that are "torque to xx ft lbs then turn an extra 1/4 turn". Those are throw-away bolts.
On another note, check the pilot bearing (bushing), better to do it now, then when it's together.

This is good news then! It means all I really need from the auto parts store is some water/coolant.
Don't mind me, just making more useless threads.

I may just move over the whole intake assembly too but I'll burn that bridge when I get to it tomorrow its a shame, brand new carb sitting on my swap candidate..
Thanks for the help! I'll take pictures tomorrow.
