Don't forget, 500 hp with Nitrous is an instant hit of power. 500 hp with FI is more of a gradual increase in power. Which is alot more tame on the street.

Plus part-throttle boost is sweet. Can't get that with Nitrous.

 

Haha no doubt about that! I remeber the first time being in his car with him spraying the 150 shot on his 231/237, I thought my neck was gonna snap when it kicked in. It pulled so violently! But yea FI def is more gradual and much more tame on the street, i just dont know if he has been in a 500 rwhp car and knows just how much power that is. FI, nitrous, or NA its still gonna be a beast to handle for someone who hasnt dealt with that much power before. Haha after my ride in my buddies car I realized that I didnt need that much power since I rarely get a chance to go to the track, only enough to handle most cars on the street. BTW your car sounds sick from your sig, any other pics of your set-up?

 

I am currently updating the site. But here are a few.

Birth
After some tuning

 

Yea i was beginning to think that too. Maybe i will onyl need about 500-600 for the street. I am really unsure. I am going to keep asking around until the time coems that i have money in had ready to buy. What do you guys think?

 

looks familiar:wink: hey if u talk to Eric let him now i tried to get in touch with him about when the longblock will be ready.you figure out the boost issue yet?

 

Haha, I have that. And want more.

 

Will do.

I would like to go with the ATI 7.65 pulley. Just don't know if it will work with the ATI Damper or SDCE tensioner. Plus I have to make sure the belt will clear the EWP.
Otherwise I guess I will go with an ASP 3.2 or 3.0 blower pulley.

 

Wow thats one sweet setup...I saw in your sig your running 7 lbs of boost, are you planning on upping it and to how many lbs?

 

Yea i mean if your looking for 500-600 rwhp for the street then you def dont need to go with a 402 or 408 short block. You can just forge your 346 and then get an ati procharger or turbo kit and you will see 500+ rwhp with 8-9 lbs of boost, and a forged 346 should be able to hold up to 12-13 psi (maybe even more depending on how extreme it is built), if you wanted even more power. You could save for a new 346 block, which is much cheaper than a 402 or 408 (I think TSP is having a GP on them now for 2700) and then get a good set of heads, a nice cam, etc and have a 346 for less than a 402 or 408. Then you could still sell your stock 346 and make some money back on the swap.

 

I just got off the phone with Wendy from SDCE. We are trying to figure out what I can do. I would like 10#

But she seems to think I should already be @10# :dunno:

 

Wow can only imagine what you will be putting down once your seeing 10 lbs of boost. Is it due to the 383's bigger displacement so your not seeing the same amount of boost or is it something else? Also, are you gonna continue to spray with the 10lbs of boost? Your vert looks sick too with the roll cage sticking out with the top down, lol must not be much of a sleeper though!

 

Edit....he just emailed me.said the heads are done but he hasnt been able to get ahold of the guy who did them,im HOPING he'll have them by friday and be able to finish putting in the lifters and pushrods and bolt down the heads and rockers and get it ready to ship.Im getting ansy as hell as ive gotta have the car done by dec 1st for a show im planning on taking home at least 1 trophy in.
and superman and 98Z....you have to remember to make 500rwhp on motor alone you need to go all out with a big cam great heads more than likely a FAST 90/90 and ALL the bolts for a 346 and most of what i listed for a 408 as well.....HOWEVER a turbo or s/c d 500rwhp car can be a pleasure to drive and be totally streetable with little to no issues.2 different worlds my friends when it comes to streetability.

 

I am sure part of it is the CI. But I think I should be around 650 rwhp. If I can keep enough fuel. But ya, I want to spray a 50 just to keep the intake charge cool.

Sure its a sleeper. Its all de-badged

 

Yea well i could jsut forge my motor for 5 grand and add the FI kit installed and tuned for about 7 grand. So i can have that for about 12 grand with pretty much maxxed out for power or i can get a 408 long block put in my car and tuned for about 10 and put down the same power as the turbo kit NA for a lot less due to 2 grand cheaper, plus i can sell my current longblock..... And with the 408 running NA i can put a power adder on top of it later if i choose to run a slightly lower comp or spray it...... ya dig, i def think 408 is the way to go for me. But for the street, build it for NA power, or build it with low comp so i can turbo later....?

 

Nice, those would be some awesome numbers. Yea one of the guys I hang with has a turboed 350z (I believe its a twin turbo greddy kit) and he has a nitrous kit simply to spray a 50 shot into his intercooler to keep the air nice and cold. Exotic Performance Plus has like the exact same kit ont heir website I believe, its a real nice set-up though and the small shot of nitrous def helped him keep the intake temps cool. Haha i actually just took the badges off my z28 and ive had multiple people ask "is that a v-8"? I mean my exhaust is plenty loud, and yet some people still dont know. the best was 2 weekends ago I had some middle aged guy pull up next to me in a late 70's earlys 80's C3 vette thats was an absolute mess (rust everywhere, engine sounded like it was on its last leg, etc) and he goes "hey does that have a v-8 in it?. I go "ya, does that have a v-8 in it?" he gives me the strangest look and goes "obviously, its a corvette man!" So i can see how your car could somewhat be a sleeper with the amount of brain-dead people out there haha.

 

Well a well built 402 or 408 is def gonna be expensive if you go with top of the line parts. I mean a forged short block is $4000 + shipping. Then you need heads, which are anywhere from $1400-$2200, cam and all new valvetrain components ($1000+), intake (fast 90/90 combo is about $1200-$1400). I mean right there your looking at about $7000 just in parts, and thats not even counting the rest of the stuff you will need such as an new fuel system, tuning, installation, etc... Figure if you dont put it together and install it yourself your looking at $10,000+ in the engine for a 402 or 408. Even built for low compression you will see 450+ rwhp, then it will be set-up for FI in the future. If your looking for huge numbers (600+ rwhp) in the future with FI then the 402 or the 408 is the way to go. In the orginal post though you said you were looking for 500-600 rwhp, which can still be done on a forged 346 with FI. It will be just about maxing the engine's capabilites out, but it will be cheaper (however the NA number on the 346 are gonna be lower if its made for low compression until you get your FI setup). If you look at the FI list in this section there are some pretty stout numbers coming out of some 346 forged setups. If your set though on the idea of going with a 408 then thats def a sweet setup that will make great power NA and huge numbers once you introduce FI. Cant go wrong with a 408!

 

I would def say to go low compression if you are certain you will be going FI in the future. As DDNSPIDER said, you dont want to have to build the engine twice as it gets real expensive. If you were going for maximum power NA in a 408 you would be going with a different cam, compression ration, etc...which would then need to be swapped out prior to install your FI setup. There are some high compression 402's and 408's with big cams, afr 225's, fast 90/90 setups making well over 500 rwhp NA, but that setup isnt gonna help you if you decide to add a turbo or supercharger down the road. I say build it once, and that would be with low compression.

 

Yea i jsut got done writing an e-mail to Allan Futral... hmmm i have 2 routes right now im willing to take...... 408 built with high comp and big heads and cam for about 500+ NA and add a 150-200 shot to that for whenever needed. So i could be at about 700 to the rears..... or i could build it with low comp and FI friendly heads/cam stuff and run about 450 hp now for a year at least before i get funds for the turbo and than i can turbo it and see 750+. Im jsut right now 50/50 to which set up to go with. One will give me big power now, and more later but o nthe bottle and the other one is less power now but later it will be insanely fast....... still 50/50

 

Since you want a DD, go with your second option

 

Yea gotta agree with Ed, your gonna have much more fun with a DD with a turbo or supercharger. You will have that power all the time with the Turbo/Supercharger. Plus nitrous is around $4 a pound where I am, so a 15 pound bottle is gonna cost ya $60 to fill everytime and trust me you will go through plenty. My buddy sprayed a 150 shot through 2nd, 3rd, and 4th gear (if he got into 4th) and he would run through nitrous like crazy. Everyone of my car friends who use nitrous say its so addicting. You start off by spraying every once in a while but then it turns into a daily thing. My buddy would spray his car on the way to work just because he was bored. So id say turbo will be the best bet. Plus like Ed said mprevious a 200 shot hits like a freight train and wouldnt be the best thing for a street driven DD.
