:D I have built many toys, a 454, 5-speed, 5.13's short bed 1-Ton GMC 4X4 on 39.5's, a 383, 4-speed, 3.73's long bed 1/2 ton Chevy 4X4 on 35's, 5.0, 5.8, and 429 Fox-body Mustangs, a 5.0 Ranger, and a 350 S-10 Blazer 4X4, just to name a few. This is my first Camaro, it's a Z28, and has 115k on it, stock internals. The kid put it on a curb, so I got a really great deal, but I have to replace the K-member, fuel lines, and air bags. I've also picked up a Vortech V1 with the 2 plates. I've ebayed the airbags, an MSD TCM, and an FMU. As long as I am pulling the K-member I am going to pull the motor and have it built into a 383. My machine shop recently did a 383 LT1 using the stock rods, a cast crank, ZZ4 hot cam, ported LT1 heads and intake, and hyper pistons, topping it off with the V1 and 8#'s that car seemed pretty crazy and I am planning to copy this setup. My questions to you are do you think this combo will stand up to 8#'s for very long? I am seeing different opinions on whether to use the FMU or go to 36# or 42# injectors. Whats the best way to go? I am going to install a walbro 255lph pump in the tank, will this support the needed fuel or will I need an inline booster pump? This car will mostly be a cruiser with an occasional trip to the strip. Should I stay with the stock Throttle body or go to a 58mm? I'm also looking for advise on headers, long tube or short? This will be my first supercharger. I have always been a cubic inch kind of guy, but I guess it is time to come into the 21st century. I am also looking for the plumbing and any additional bracketry needed for the Vortech. Any advise would be greatly appreciated and well taken.

Thank you 96slow6, very good information. This seems to be a very informative site and you will probably see me here quite often now. I had my doubts about the stock rods as they are powdered metal, but I don't have much experience with them. Your position on the FMU seems to be the same as many people and just makes my decision final. The heads are not in the funds immediately, but will be soon to come as soon as I diminish some of the other toys. Does anybody have an opinion on the strength of the Scat or Eagle cast crank and KB Hyper pistons on a S/C stroker motor. How about the caps? If I understand correctly they are 2 bolt. Should I go with a 4 bolt spayed?

[Zupercharged28]

yea id go with the bigger injectors (42s just in case you ever wanna up the power)... on 8 lbs. on stock rods and what not.... (depending on how you drive) i might last a goooood maybe 3 trips to the race track? anyone wanna help out here? id definitly put a forged rotating assembly in if i were you (since the motor is being built anyways)... you can get fully forged 383 kits for like $700-900 and that way you could run 11-13 lbs all day long at the track. that will be a nasty car when its done though! welcome and youve had quite an array of vehicles havent you? slow knows exactly what hes talking about dont listen to him say hes not up to date. MOST absolutley go with scat internals they are extremely quality. if you can pick up a cheap 4 bolt main (should be like $100 for a stripped one) then absolutley do that. it would be such a help when youre running high boost. so much more durable.

[chasmosis1]

Wow, this is a great site! Thanks alot Zupercharged28. I think I will go with the 42#'s. $700-$900 sounds like a hell of a deal for a full forged assembly. Have you got any links? I would like to have a solid bottom end to start with as I know that I will eventually need more power (it'll never be enough power). I have had quite a collection of toys, I've always had a head for horsepower. This will be my first time playing with forced induction, but from my research it seems to be the only way to play. Now onto the 4-bolt block. I am a little confused. Is the LT1 block the same as the 1-piece main blocks? If not than my research tells me that the only time the LT1 style block was used is in the Corvette LT4. Is this correct? If so than it seems that it would be somewhat difficult to find a block for $100. Experience with past blocks is that a 2-bolt block drilled for 4-bolt splayed caps is actually stronger than the stock 4-bolt block. Any input on this? I apologize for all of the questions, I hope they don't seem ignorant. I am a newbie to the LT1 motor and forced induction, but I am very experienced to engine building in general.

Here is your website: http://dynoflow.substorm.com/rotating_assemblies/rotating_assemblies.asp
Best value I have seen thus far. Good choice on the forged internals, running 8 lbs otherwise would have been a miracle to make 3 track trips. I have had a handful of LT1 blower cars now and am pretty experienced with them. Anymore question, give me a holla!

i wouldnt worry about the 4 bolt. when was the last time you heard about a main cap of anykind breaking? and no not just lt4 vettes were 4bolt. most of the later lt1 vettes were 4bolt. and all gm aftermarket and replacement lt motors were 4 bolt. and as for drilling a 2 into a 4 i think it is a bad idea. you are drilling into an area not designed for it so there is less material so to me that would be weaker. as per for sure i dont know. and snigga is who i was hoping would pop his head in along with zuper. they have great info. and no question is stupid as long you can get it out in an understandable fashion.

[Snigga]

...and snigga is who i was hoping would pop his head in...
Aww shucks, you're gonna make me blush.:rolleyes:

you know you love the attention.

All I can say is dammmnnnn!!! Snigga! I asked for a site and you gave me a site with the most unbelievable prices that I have ever seen! I will definately be ordering the LT1 383 Top Sportsman kit with the forged crank and H-beam rods. I see that the kits only come with flat-top or domed pistons, but I will give them a call tomorrow and see what my options are and if they offer any dished ones. I am still shocked by these prices. Have you ordered from them before? Shipping shouldn't be too bad as they are only two states away from me. Damn, Merry Christmas to me! It looks like I have found my bottom end. The owner of the largest machine shop in my state is a friend of mine, so I am gonna see what he has as far as 4-bolt LT1/LT4 blocks tomorrow. After doing some more research I do know the difference in the blocks now (I feel a little stupid for asking that question, and by the lack of response I know it was a stupid question). I have been a member of quite a few auto forums in the past few years and I must say that this has been the best welcoming commitee that I have ever experienced. Most sites you would be lucky to recieve 6 views in a 24 hour period, no less 6 replies. Thank you all for the responses, I think I have found my home!:lol:

[Snigga]

Have you ordered from them before?
No, I have not personally ordered from them...yet...My last blown LT1 was a 355 setup and I loved it. It just so happens that I have been looking into building another blower car.

[Zupercharged28]

snigga knows whats going on....everywhere at all times. hes one of the men to go to. slow is another. camtom and grims are always helpful, insightful, and full of tons of info too. chris is a beast too. any of the mods actually. they all know everything. any questions give anyone a holler! dont be shy and thats what everyone is here for, helping eachother out. im jealous of your forged 383 kit :-) i wish i could afford that soon.

[chasmosis1]

Good deal, I appreciate all of the help. I have found that 2 of the local machine shops are willing to get me the forged rotating assembly also. They can get Scat, Eagle, or Probe (never heard of Probe before yesterday)? I'm leaning towards Scat at this point, but would like to hear opinions.

[Zupercharged28]

im going to shoot for scat.... when i can finnaly come close to affording it...
:-(.... i have heard nothing bad about them! and the name kicks butt.
