Engine build

Post by bezhawk »

So I'm doing another build and want to go "whole hog" on this one. Looking at rods, and wondered if anyone has looked at the 5.4 Ford modular V8 rods? they are close in length, and big end bore. Let me know what you think.
I will be needing good parts soon, let me know.
Already have the R3 heads, ATI dampener, Roller cam blank, Sniper Fuel injection, so anything for a super lower end, and forged pistons would be of interest.

So what would you do about rod bearings. No way to get to the 2.0 inch rod journal size with those rods. You may just have to spend the money for custom rods. Of course you will need custom pistons.

First, what cubic inch are you building toward? What stroke?

FWIW, I've used custom rods costing from $500 to $2000, so what's the budget?

I saw where they were available in 2", now I cant find it. Poop! The budget is not to spend so much as to not build it! I think about $5-7k is where we are thinking But...I don't want it all in the lower end! There has to be room for labor!
I think a .060 bore to 299.28 is where we want to go in order to keep some meat in the cylinders, incase we decide at a later date to up the boost with a turbo instead of the Paxton.

Many of us have been thru this.
But without good details from you, no one is going to be able to do much to help you.
Remember, excellent details are the key to a excellent build.

I looked at those rods at one time and even considered checking to see if someone who built those rods could build a modified version. Long story short I ended up with some custom rods at about $1600 quite a few years ago. Not sure where Jack got rods for $500.

Well, the reason I guess for posting, is to see who has what, and hope that they pm me with some good parts that they might want to sell. Or maybe it was just to be corrected on semantics and spelling. Yeah, that was helpful.

Interesting comment. That is not what you asked in your posts..!
Again, the "details" count.

Hi, David,

Agree, custom Stude rods are closer to $2000 today.

I detailed how we used $500 Eagle flathead Ford rods in a full-race build and so far, so good.

As to other options, I've got probably the last set of Howard's rods for the Studebaker V8. I hadn't really planned to sell them, but would discuss it.

I forgot about those rods. They were not suitable for what I wanted and I didn't like the size of the wrist pins. However if you are only looking for an engine in the 400-500 hp range they should work. I don't remember what rod bearings they use but are for 2.000 journals.

I'd rather use "H" beam rods.
Stronger and can be as, or nearly as light.

My Crower, "H" beam rods are lighter than stock, my pistons are lighter than stock. Balancing the rotating assembly was easy I was told. Almost no work on the crankshaft was needed to complete the balance.

Hi, David,

The flathead Ford rods use a Buick 2.00" rod bearing, but since the Stude crank journal is much wider, the small journal SBC bearings could be used and there is an infinite selection there.

The wrist pin is .750" and if one is ordering custom pistons, a thick-wall race pin can be specified. As light as Stude forged pistons are, I don't think that would be the weak point.

Yes, these went in a normally aspirated 259" required to run the OEM intake and exhaust manifolds and thus far it's making 275hp @ 5500. With the 200 CFM heads Mike did for it, the DynoSim says it could make 400 hp @ 7500 RPM with a 2x4-bbl tunnel ram and and headers. Unfortunately, the good heads are wasted on the stock intake. I'm going to remove all the dividers in a late 2-bbl intake and add a spacer to see if a larger plenum will help at all. Any and all suggestions appreciated.

Ok, so I purchased some good stuff from a retired Bonneville racer, and got some serious parts today. Carillo rods, and Arias pistons, and a good roller cam . The pistons were 8.7 with 68CC heads, so with my heads I'll shoot for around 60 CC if they are not over that already. (I haven't checked, and I don't know...yet). Also 6 bolt billet mains for the center three webs.
I do have a single turbo, but I think it is too small for any serious power, so I'll get a 2nd and I think that is the route I'll go.
I have an old TPI intake that I am going to make a base for and use a megasquirt for the injector controllers, and blow into that. I have a 2 bar map sensor. Already have the roller lifters ordered.
So, things are moving right along.
