This is really the first time I've ventured off into a combo that is 4 digit power capable and I'm trying to get an idea of what to expect for setting up the rest of the truck. Blower is an F2 procharger and I've got a PT2000 A2W. BS3 EFI using an external crank trigger.

Motor should be finished in the next few weeks. Looks like this:

6.0 Iron Block bored to 4.030
4" Crank
6.125 Rods
Compression will be 9.5:1
Solid Roller cam (Hippo lifters and Crower shaft mount rockers)
I don't remember exact specs for the cam but its around .715/.735 248*/258* at .050 on a 116
Heads are 245cc edelbrocks that have had some work done to them (Its been a month or two since on the flow bench but I think they went about 360cfm on the intake and about 260 cfm on the ex. at .700. They where pretty fat in the middle too.
For now I'm gonna use the Vic. Jr. I already have, elbow with a 90mm tb
2" kooks w/3.5" merge

Power is going through a built 4l80e

I've got several questions.

I've got a 77t/54t pulley setup to try which should have the blower around 54000 rpm at 7000 engine rpm. Or about 83% blower speed (of the recommended 65k max).

Anyone have any idea of what kind of power this thing will make? I'd like to start slow and work my way up to avoid tearing **** up.

Also, I'm wondering about my fuel system. Right now I've got a Magnafuel 4303 (-12 feed, -10 split to -8 to each rail), and 120lb lucas injectors. On C-16 will this be enough? I'm thinking I should go ahead and upgrade to 160's or bigger and/or a 4703. Any thoughts?

Also, I'm wondering about the converter. Right now I've got a 9.5" triple from precision that was freshened by chris at circle D. It went about 3500 on the foot brake behind a 346" D1sc combo I had. Am I just gonna blow through that now?

I'll start with that...

I think with that much compression your going to make too much power. You will have to spin the blower slower I think. That converter probably wont work either. I have one that should work if your interested. I would lower the compression a little more to give yourself some room. with 9.5 you could make around 28-30lbs. At least I think it could. Definitely will need the 160 injectors. I think with that blower speed you will make close to 25lbs which should be around 1200-1500hp depending on how well built your engine is etc.

Unless I missed it, is this still a four bolt per cylinder combo? Bob

I just realized, is this going in a truck?

Yea, going in a truck. '06 rcsb, all chassis work done by madman...

...and yes Bob, this is a 4-bolt cylinder head. Sounds fun huh?

Fun setup for sure but you will not be able take advantage of that F2 with 4bolt heads how much boost are going to run?

Keep us posted what are the goals from this setup other than 1000rwhp ?

That was exactly what I was thinking, are you going to have it o-ringed? Bob

If you are going to use a 4 bolt head. I would suggest modifying the head and block to use 1/2" head studs. That will help some.

X2...if your going to try using the 4bolt heads get the block and heads machined to run 1/2" head studs and get the block/heads set up to run a pyrymid ring setup. It'll be a nasty combo for sure...I'm getting ready to start something new as well. I would worry about the 4 bolt heads taking that kind of power with regular gaskets.

I know its not the best combination of parts, but I'm using what I got. I got a crazy good deal on the blower and cylinder heads. I didn't have the money for a 6-bolt build. I know there are mixed opinions on the subject, but I don't stay in the 1/2" head bolt camp. My opinion is that clamping force from the bolts isn't the problem, its the distance between them and the head flexing. This is just my opinion from the information I've read. I don't know for a fact.

I'm hoping that I can get the blower slowed down enough for 25lbs to get me started. The goal is to get it to hold about 30-35lbs, but we'll see.

Other than that, I really don't have any goals. I'd be embarrased if it only ran 9 something, 8's wouldn't really suprise anybody and I think 7's is a pipe dream with the weight.

I bought a BS3 system with external crank trigger and it came with the wheel and pickup but no bracket to mount the pickup. I'm running motor plates so mounting shouldn't be too big of deal, but does anyone make anything that I can buy off the shelf to work with motor plates? Below is a pic of the front of the motor with plates, blower brackets and water pump. I still need room for alternator. Can anybody point me in the right direction for this or will we just have to fab one up. Also, I need to incorporate a timing pointer as well, any ideas or something I can buy off the shelf that will "bolt right up"?

That seems like a pretty stout bracket on that their motor

Post some pics of this beast. Sounds like a cool project!

If it isn't too late I would get your engine builder to o ring the block and heads for piece of mind. Seems people forget these motors were able to hold good power before they made a 6 bolt block.

I'm hoping I can keep it together around 1000rwhp for now. If the F2 will let me back it down enough. I can always shift it early to keep boost down till Im sure everything is perfect in the tune.

Here's a couple pics for ya

Clean truck! It is going to be an interesting build. Bob

You can hold it with 4-bolt heads. I made 1021RWHP with a YSi, 408 iron block, ARP 2000 studs and LS9 gaskets installed clean and dry. Then I added a 150 shot on top of that. I recently took the motor out after deciding to go to a 434LSX and 6-bolt heads, but I can tell you that I paid close attention to how well that combo held up and there was no breach across the sealing rings of the head gaskets. None. For a reference, a friend of mine picked up 136RWHP off a 100 shot from the same nitrous supplier. That should put me at 1200RWHP easily on the 150.
Taylor from Dallas Performance has been doing F2's on a few cars lately. Based on his results of 1400RWHP from one car, I would guess you to be around 1050 since you're going through an auto.

Here's what I'm finishing up.



Great looking truck!! Can't wait to see the finished product!

Everything except the converter looks good for an F1 but the F2 is going to show week spots real fast.
