EVIL 6.0

This is my first motor build and I'm no expert but I believe that is just describing the heads. My bore shouldnt change. I know the block will probably be honed.

I'm kinda learning as I go along here.

EVIL 6.0

See I did alot of research on a LS3 fast 102 vs ported LS3/L76 intake and the results were poor for the 102. There were gains but they were minimal. I could spend the extra several hundred on a 102 and 102 TB and maybe see a 8hp gain. It just wasnt worth it to me. If anything restricts me it will probably be my MAF in which case I may just go with a SD tune.

After labor and parts this build will be around 10K so I have to save where I can. If Ryan at RPM says the intake is really choking the motor I will wait till tax season and do the Fast 102.

you have a slightly bigger cam and way better heads, I dont see why this car shouldnt break 550rwhp with the 6 speed. Plan on a mcleod twin disk! I also agree with your choice on the ported ls3/l76 over the fast 102. The ls3 is 230 new and will get you within 10 hp of the 102 setup. I had no complains about mine on my prc l92 combo. Whats the timeframe of completion?

EVIL 6.0

Thanks for the advice. You dont think my Monster level 3 will hold for long then?

And Shane has my car now. I'm waiting on new motor mounts to come in and then he is taking it to RPM. Should be going this month. I don't know how long it will take them to do everything though. My guess is a month.

I dont think there is really a single disk that will hold a stout motor setup at that weight, at least for track purposes. You could probably street drive it easily. But the mcleod will be worlds above what you have now,.

EVIL 6.0

Yeah makes sense. I seen Monster came out with a twin disc. I'm sure I'll switch to that or the Mcleod.

Nonsense. The level 3 monster will hold that power. If not monster will warranty it. The level 3 is good for over 700 ftlbs and there are other levels above that.

Let me clarify...I agree a twin would be a much better choice, however, why fix what ain't broken?

EVIL 6.0

It may hold for a while. And your right, I do plan to throw all I can at my current clutch unitl it goes. We'll see how long that will be.

Going back to your FAST intake vs. L76. I did the same research you did before deciding on a FAST. Most of the engines that were stock cube whether it was 364,376, or 370 with a FAST 102 didnt pick up anything or even lost with a 102 on there. When it came to stroker setups I noticed the bigger cam motors would pick up more vs. the smaller cam motors but the strokers would pick up period, over smaller cubed motors. If it didn't there was another issue.

The L76/LS3 was designed well for stock cubed motors and a little bit bigger, but when you go 400+ cubes a FAST becomes the last piece of the puzzle to complement everything else.

I made 554rwhp through an unported l76 intake, i dont see a fast picking up enough power to justify the $6-700 price difference. I annihilated a single disk that was rated to 750 ft/lbs in less than 15 passes in a 3700 lb f-body. I would just do the upgrade to the twin disk now, while the engine/trans are out rather than worry about it leaving you stranded and having to pull it all back out again.I'm Proactive vice reactive I suppose.

EVIL 6.0

I see your power Brandon and it makes me happy I went with the ported L76. Maybe if I get a bonus down the road I will get the Fast. Really, the highest HP 402 I have seen was in Nick Williams 402 Vette which made 470 I believe.

Theres alot I want to buy right now like a twin disc, new drive shaft, and a tru trac LSD but I really dont have the money now. I still have to pay for the rotating assembly and labor which should be around 5K total.

Trust me I know. It will peak early. Check out my motor it peaked at 5800. It will spin to 7400 but why when its all done by 6400. Your build will still be a fun ride. mine has been for 2 years. I have a Mamo 102 waiting to replace my 76 intake. Then we will really know.

EVIL 6.0

Its hard to tell what my power curve will look like right now. I have not seen these heads ran on another stroker. I have about a year left in the Marine Corps and trying to save a bit before I get out. The heads alone cost alot so I had to make smart cuts in the build with something.

This is one of the thread I read through and it gave me no reason to buy a LS3 Fast 102. Even another 402 guy said he gained nothing going from a stock L76 to a Fast 102.

just buy a short block from one of the sponsors, and sell your ls2, you'll come out only spending maybe $2-2500

EVIL 6.0

I've looked into that. TSP's 402 short block is around 4500. I would still have to have things like my link bar lifters,head bolts, and oil pump pulled off my motor. I have a buyer for the heads and cam but not for the block. If I was home I could assemble the longblock and install it. I will shoot Ryan an email and see what options I have.

If this what you did? If so could you shoot me an email explaining how it all went down and what you got for your block?

I'm in for the #'s this puts down. Nice build.

EVIL 6.0

Motor mounts shipped out yesterday. And I just got these Fast fuel rails from a friend. New fuel pump is getting installed now and the car goes in this weekend.
