duanesmith.net - ARP bolts and studs

Plan-	what I want to do
Everyone seems to agree that the best bolts for building the serious engine are made by ARP. While spending the money to have the engine built in my Supra, I might as well go the extra mile and be sure to assemble it with parts that can handle whatever I decide to throw at them. Hopefully these will keep me from having to dig into this thing a fourth time.

Project-	what I did
Not a lot that I can write here as right now these are still sitting in boxes on a shelf.
Top

Difficulty-	things that made it hard
1- This depends of whether I have the engine assembled by the company doing the work, or do it myself.
Top

Problems-	with the product/install or that came up later
1- I need to see if ARP makes bolts for aftemarket rods, the bolts I bought are for the stock rods and won't fit my Crower rods.

Payoff-	what I felt the "bang for the buck" was
Hopefully a big payoff in reliability.
