I just added a price, thanks for the heads-up.

Hello, These rods are full custom H-beams and are in good condition. They also have the best rod bolts that money can buy (Carr bolts.) The small end is tapered and there is forced pin oiling from the rod to the piston pin. They have a lot of work and detail into them. I purchased an engine...

There was some good info on here that I completely missed. I have bought the parts, but I haven't started the build yet. I'm still trying to decide on if I should run a 2.5" collector or a 3" collector. It would be nice to know the difference in spool time between the two. I don't think I...

That's close to being true. I didn't want to say it because I wanted to get as much help as I could. Truth be told I'm going to the SVO V6 which is a completely aftermarket based engine that is similar to the Stage II engine. It's a 3.400 stroke and a 4.130 bore with 360cfm heads...

I've called them and got anywhere from 7675's with a .81 T4 to 6262 with .82 T3 housings. It's like shooting in the dark to decide. I understand what you mean about the boost. I suppose if I were to keep it at 900rwhp, or 15psi, then I would like to hit that by 5k. Not necessarily all...

Thanks, Dusty. I called Precision up and the tech there told me that I shouldn't go for anything bigger than a 6266 with a .82 A/R T3 turbo. He said it would be too lazy. If I had full boost by 5k, then I would be happy. Optimally I would like to have full boost by 4500 RPM. From what you...

Anymore suggestions?

Do you remember what size tubing you ran to the turbos and the rpm it spooled at?

I was wondering what a good twin turbo setup would be for around 1400rwhp. I was thinking 6766's, but I can't decide on the correct hotside to run. As far as primary sizes go, I am thinking of 1 7/8". As far as turbos go, I was thinking either 2.5" tubing to a .81 A/R T3 or 3" tubing to...

I'm fairly confident in the equilibrium between the each cylinder. My concern is that I may be over powering the 7/16" studs at 90 ftlbs. There are only 8 of them per side. If a head lifts and the flame encroaches the surface of the block, heads, or the gasket, they will become torched. Doesn't...

I'm tuning using the gas scale, on an LC1 wideband. The plugs look very clear, so maybe it still isn't rich enough. I may just go ahead and have the heads decked, although they look good. I'll definitely check the block's deck, too. I'm ordering new head studs. What size are the head studs...

The SC and GN motors are similar, in design. I'm just trying to get some general info as a 3.8L V6 push rod motor. The port configuration is like the GN. The intake also has equal length runners. I'm going to purchase new head studs since I am skeptic of the ones I have. They have been...

I'm running a factory 3.8L (stroked to 4.2L) Ford V6 from a Thunderbird SC. Nobody has really used E85, so this is the closest comparison I can use. Sorry, I generalized to try and get more responses by removing potential bias. I'm using an Aeromotive A1000 fuel pump with a dual -8 AN feed...

I was at the track and started having problems with leaking HGs. I pulled the top end apart and found that the head gaskets were torched on two cylinders. At 25PSI and 750ish RWHP, I didn't expect the motor to detonate, but it seems to be what happened. My timing is at 22* and AFR is...

The injector driver is AEM purchased new. The injectors were also purchased new and flow balanced (154 lb/hr at 43.5 PSI). I only have about 100 miles on both of them. I have some weatherpack connectors that I wired the the factory harness with, so I can easily bypass and/or disconnect the...
