I or H
Which do you guys prefer? This would be for a 355 build. Maybe see some juice but nothing serious.

It really depends on how much power you plan on making and how fast you are going to spin it.

i agree because H beam rods will cost u more at the machine shop clearancing for them. and a set of forged I beam rods r strong unless ur plannin on sprayin lik 200+ or very often

There always been what seems like allot of debating over which is better and why? I think the majority of people run H beams as there is less clearance issues and cost.
My engine was built to support 750+ HP at 7,000+ RPMs, it has Manely I beam rods in it. ( they were not cheap! )

Well its gonna be 355 build with stock crank, and new rods/pistons. I wanna feel safe spinning it past 6200 but prob not much higher. Perhaps some juice later on, which is why I want to go with forged stuff. So its a little past a budget build but not an all out build.
I was thinking Scat H rods.

if i were you id go I beam save yourself about $200 and they're still very strong and i think the crank would go b4 them. and 6200 isnt high at all.

Stock crank is seasoned, people have pushed it pretty far. And I wanna try to go overkill so I decide to upgrade later, I can use the same parts. And I know, 6200 isn't that much for a drag car, but where would you spin it that high on the road? And my cam peaks out around 6200-6300.

So I was doing some window shopping, and Scat forged rods, both I and H are rated to 750 hp, whats the deal with that?
Also, can anyone explain bushed vs. pinned?

H <> I Look at the weight and material used as the main reasons for their HP ratings. The design H or I has less to do with what HP they will support compared to what they are made of. I 'think" some manufactures perfer H or I as well. With mine the I's were listed as stronger then H.
Think they are referring to Pinned/brushed relates to the rod pin that holds the piston to the rod.
Pinned = Rod pins are pressed in. ( most common )
Brushed = Rod is free floating and held in with retaining clips. (Mostly for all out race egines that are trying to squeeze that last 1 HP out).
** I have no idea why it would make more HP? Maybe with it free floating there is less drag as the piston moves/changes angles???

So bushed would be the better bet for longevity?
And now onto the next question, rod length, I have heard a lot of different opinions.
I was even told to go 5.85... any logic?
What do you think of the 5.7 rod allowing for more heat or something?
