Rod and Main bolts`
OK...so I'm looking at buying a set pof bolts for my rods and main caps. I'm looking at ARP and they have a set of Main bolts for about 25 bucks which look strong... Then I find their "pro series" set for 70 bucks. Now, is it worht getting the $70 set? I'm looking to run NOS after I'm done building this engine. I have a complete forged bottom end so I'm thinkin after i spent so much already might as well go all out. However, don't want to do that if it isnt necessary. Anyone know anything about it? Thanks

Re: Rod and Main bolts` (SRVFAN7)
Bottom end advice? Are you talking BB or SB? Stroker? 2 / or 4 bolt block ?, crank/rods?, how much HP are you going to make and @ what RPMs? I take it you just you plan on short bursts? (1/4 mile). Tell us more...
I use the best fasteners I can find. The 4 bolt 468 on my engine stand right now has ARP main studs, and ARP 7/16" Pro Wave-Loc's.

Re: Rod and Main bolts` (Twin_Turbo)
Studs? I was meaning to ask about those as well. Are studs better? I can find them for the main caps but I don't think they make end for rods? For the Main Studs, it says with or without windage tray. Is a windage trsy s good buy for the pan?

Re: Rod and Main bolts` (SRVFAN7)
The studs dissipate the load better than bolts because you screw them in totally and they distribute the load over more thread area. A windage tray is a good idea too, check your pan. Some pans already have a GM tray in them.
Stock rods only have bolts, no studs. The bolt face is chamfered and the cap is sectured with a nut. The cheapest arp bolts/nuts are a real improvement over the stock bolts/nuts. They could very well be the weakest thing in the stock bottom end (stock X-rods aren't too tough either & the caps are thin)
