Granted he put down 415rwhp and is on worn out 325/50/15 MTs, but i like mine the best

An actual street race? He can pull me by about 2 cars from 0-120.

a LS1 IS a SBC

technocly its not..

What is the 3rd gen running for exhaust?

brodyscamaro

Technically it is a Generation III SBC.

CashMunson

iTrader: (1)

it's a SBC with a slightly different design. it's still a sbc motor.

SilentNight1647

It is but it isn't traditionally the LS1 is not a Small Block, technically it is, take your pick either way they are both good mills. Nice burnouts by the way.

It is still a small block. GM has 5 generations of small blocks now. The one we are most familiar with is the Gen I which ran from 1955 all the way to 2000 (for some models). The Gen II ran from 1992 to 2001 (in certain vans, only till '97 for the f-bod), the Gen III (LS1, LQ4, etc) went from 1997 till around 2004, the Gen IV went from 2005 till today and the Gen V is now making its appearance (new ZR1 motor, next version of the LS7). A "big" or "small" block is defined by bore spacing and not cubic inches or external dimensions. Every time GM significantly changes the architecture of a new V8 (oiling, valve angle, and bore spacing) it designates it as a new generation.

i thought anything past 400 is bigblock?

Stephen

Small block vs big block has nothing to do with cubic inches. There were 396 big blocks, and 400 small blocks.

It has to do with the architecture and physical size.

I have a 406 small block, bigger than a 396 BBC in cubes but not in bore spacing and stuff like mentioned before.

Going stock LT1 catback shortly with a 3" e cutout, and a 3.5" mid pipe with a dual 3" Y to 3.5".

As mentioned there are 400 big blocks and 400 small blocks. You hear the old statement all the time; "A hot rodder knows the difference between a 400 small block and 400 big block". If anyone ever asks you this question the answer is bore spacing. Yes the physical size of small blocks versus big blocks is different but that is not what separates them. Small blocks (of each generation) share the same bore to bore distance (center to center). Likewise for big blocks.

Despite the major differences between the generations I believe all Gen I, II, III and IV small blocks share a 4.4" bore spacing, thus deeming them "small blocks".

Not at all....

I was just about to mention the World Products Small block 454. You beat me to it. In fact just last weak I was reading a Car Craft article where they tested the World Products 454 small block against an equally built big block 454. Funny thing was that the small block produced higher peak horsepower and torque, and across a much broader power band.

That 4.4" bore spacing is what limited the LT5. Mercury Marine said they could build GM a more efficient engine if they changed the bore spacing but GM wouldn't allow it due to tradition.

ah yes, the elusive lsX block, lol! that thing can handle 500+cubes depending on stroke/bore combos.

I gotta know, does he pull you by 2 cars with you on motor or on spray?

MaxxMitchell

iTrader: (4)

Motor

Weather got crappy before i could use the bottle with him. He lives like 2 streets down, and ill be installing the bottle on his car this winter. Hes got a built 347 LE2 heads/cam package, Fast 90/90 intake, and went 11.40 @ 118

ZONES89RS

iTrader: (2)

Sweet, i have olmost the same motor as you but i think my heads might be a bit more.


When do you shift? My car falls on its face at 6000 rpm but everyone tells me it might be due to the HEI. I dont have MSD but as i have the same cam and cubes and even compression as you i am trying to compare it to mine.

MaxxMitchell

iTrader: (4)

I have a MSD HEI module/coil, im switching to a digital 6 to retard the timing for spray automaticly instead of me turning it back here shortly. Ive also got a edelcrap 750 on there, that runs lean in power mode even with pretty oversized jetting.

Currently im shifting at 6-6300 where i have the limiter set at 6500, the car picks up strong at 4500 and pulls great untill i shift. Air fuel is a bit lean currently in the high 13's range at WOT, but on bottle it held at 11.5, so the car will pick up pretty decently with a new carb.

What heads are you going to run? The protopline vortecs do decently

ZONES89RS

iTrader: (2)

They are a 292 casting from 1970, they are a over the counter part from GM, they flow like old regular heads till ported, theese are ported WAY out. They were pulling 7000 rpm on a different car with a huge cam, but they were not running HEI.

iTrader: (9)

well they screwed it up them selfs. it should be.....

SBC (I, II)
BBC (can't recall all the little names)


GMB (General Motors Block) since it is now a true corp. block and retains the basic shape and size for all cubes now but "LSX" or "LS_" usually is what we use

SO he is right

ZONES89RS

iTrader: (2)

Generally it is Gen I, II, III small block, then Big block, i think goes mark III, IV and what not. Not enough parts swap out for a GEN I, II to a GEN III so it makes it easier to know what is what so we all know the LSx has olmost no parts that swap out.

TTA 1387

Technically it is a Corp Block made by Chevrolet. Just like the 3.8 V6 is a Corp Block made by Buick.

Its a small block chevy. Obviously GM thinks so also or they wouldn't call it Gen I, II, III, IV.

your buddy just needs to learn how to do a burnout. Seems like you've got it down...

jay_d

you know why he pulls on u by 2 cars? cause his car hooks up alot better....just from video i can tell that

MaxxMitchell

iTrader: (4)

not really, i can take him by about 1/2 car from a dig when i have the stickies on while he has to lift to make his bite back up, im stuck and gone, and he will come around me at around 70, and pull to about a car between us at about 120-125.

Ran him again last weekend me on those same little street tires, 25 punch he would pull out his 2 cars while i was spinning, then hold until 110-115 then i would start bringing him back in. I jetted the carb as rich as i can go and im still a bit on the lean side, so ive got another one coming.

Now my car is down for a little while, im pulling the stock suspension off finally, and going QA1 adjustable shocks in the rear, and bolting on my lCAs and brackets and TA. Should help out with the street tires more, and the fact i cant squeeze it until mid to top of first on the stickies.

Hes planning on going all out on the suspension stuff this year as well. Wants to do about every chassy add on you can including a front K member. LOL so we'll see.

Me hooking up a bit better:

Following that standard though, there shouldnt be a sbc2 either. It was a corporate engine also.
