Re: Math

i know its like this one

.500 x 1.6 divided by 1.5 = .533 ;)

I understand your math even though it is not the way to determine valve lift.
My example on the other hand is for something different. I'm waiting for someone to pick up on the measurements and have an opinion. I need to get two parts in my hand to measure some other things to see if they are the same. If the spread is the same, bingo, new option for us.

Yes. If the center to center distance on the rod bolts is the same as a small block, bore the small block big end and instand rod upgrade. Your choice of small block rods is great and most are better than eagle. I am not a fan of eagle for any of their stuff. Cheap overseas crap imo.

Re: Math

But I thought the width is different too?

Could be. I need to get both in my hands. Going +.125 on a small block rod is easy and has been done before. Must be a reason why peeps have not done this before.

Re: Math

Since small blocks dont have a huge problem braking cranks, why cant we turn our cranks down to fit the rods? We could get the width machined down if they are too wide, if too narrow.....were screwed though.

Re: Math

If you turn the cranks down that much you are taking away material that is needed for strength.

Re: Math

I was under the impression that honda 1.88 where the upgrade in a small block. The theory I heard behind this was less surface area mean revs easier and faster but not sure

That is true for SBC. But we have a split pin crank. The extra material is there for strength & they need it!:2cents:

Re: Math

Stock rods, eagle rods and Olivers rods that are made for our cranks are offset from side to side. You can can narrow a SBC rod +/ .010, but the rod will not be center. Some of us had tried this and had rods that were off center enough that they were cutting into the pin bosses. It is best to keep our rods close to piston center if you are running a decent amount of boost.

The eagle rods are the best rods going for our builds. I don't know of anyone breaking or twisting an eagle unless they had an improper tune and detonated the motor to death. The Olivers are just some added insurance, but a bad tune can get them also.

Re: Math

Thanks John. Always wondered why peeps wern't going there. I'm thinking of a build for big power. I have a builder I work with that has the absolute latest in small block technology and we want some really trick stuff in this build. Neither of us are eagle fans (football or rods/cranks) so we started thinking elsewhere and I just did not have the info for him so he was throwing ideas out. Onto plan B.
