NOVACRAZY2007

Hello everyone. My name is anthony and i'm new to the awesome ls world. Well i have a 70 nova that i drag race. It has a sbc 350 gen 1. Well i run a 6.70 1/8th mile at 101mph on 150 shot of nos. Well thats not fast enough. There's a new index class next year that i want to be in. Its a 5.50 index. So i'm pulling the motor and selling it. I bought a 2002 lq4. Want to build an insane carbureted high hp engine. Looking for help with forged pistons, head choice,cam, and intake for it. Going to run on race fuel. 600hp minimum. I'm going to use the same tranny which is a rossler th400 with brake. Strange axles s60 with spool and 4.10 gears. Need help with ls family engines. My first one. Thanks.

I think a 408 stroker with ported ls3 heads in your future. Look at the sponsor list and talk to Geoff at EPS for a cam. He can give you good advice on what you need.

If I were you, I would just punch that lq4 .030 over and build a 370. My 370 with mahle l92 pistons, eagle rods, stock crank, ls3 heads, victor jr intake and a Patrick g cam. I should be extremely close to 500 wheel which is near 600 at the crank. All this is before my nitrous.

Whta kind of heads should i use. What compression?

whats your budget like? parts like forged internals are like triple the price of a SBC. you can make 600 rwhp fairly easy if you still want to use nitrous. what are your class rules? or is there none you just have to run a certain time?

i would keep your stock internals and fly cut your pistons depending on cam size, use ARP 2000 rod bolts, ARP Main Studs (optional), ARP Head Studs, a good set of nitrous rings, mill your 317 casting heads .030 and clean up and gasket match them, use a super vic intake, custom cam, some 1 7/8 longtube headers, and a 200-250 shot. should get you past the 600 rwhp range and be a fast inexpensive reliable combo if its tuned right. than upgrade to a forged 408 later

I have a 3000 budget. So i should go with the l92 heads. There the same as a ls3 head? I'm going to use nos. Going to keep my sniper kit that i have already. I was thinking stock crank, block .030 over, scat rods, probe pistions, victor jr intake, 750 hp carb, custom ground cam.

Since a low budget build is the goal, and keeping it at a $3000.00 budget is really wishful thinking....
....I would spend the money on a stroker shortblock and run some stock L92 heads for now.

You can get a pair of used L92's complete with rockers for around $300-$400.
They will flow 320cfm and you can always have them ported next season. I would run the Victor Jr L92.

If you are planning on spending the cash for new rods and forged pistons, you might as well get a stroker crank to match.
- Overall it's only a few hundred more. Cheap performance increase, really.

A complete stroker 4"- 408" or 4.1"- 418" rotating assembly can be had for around $1550.00
- crank, rods, pistons, bearings, rings.

Several vendors on here could also sell you a complete rotating assembly.

Will 6.125 rods work in my block. I know the deck hights vary.

The deck heights only vary in LSX blocks. Being a lsx block offers a High deck version.
So yes, 6.125 rods will work, they are actually the most common aftermarket rod and the most easy to find a matching piston.

From my understanding.

I would go super victor intake, for a little more money its a much better intake. If you have a 750 carb already it will work but I think a 950 would be much better for this set up. Scat 6.125 I beam rods with the 7/16 bolt is actually a nice rod. I have them in my Nova engine and not to heavy yet very durable. An ls1 makes a lot of avg power so even if you dont quite make 600 hp, the car will still run very strong with this set up and the right cam shaft. Make sure to get the cam custom ground as the l92 heads dont usually work well with a cam built for cathedral ports and also the single plane intake requires a different design then a stock type intake.

try to use ls3 casting heads with the hollow valves instead of l92 heads. they are basically the same head other then the valves.

im assuming your gonna build the motor yourself? is so you can get it done with 3k. and you already have the LQ4 paid for correct? with 3k your really just gonna have to decide were you want to spend your money. also if you spend all of that 3k on the motor whats the rest of the car looking like safety and suspension wise? do you already have enough cage for how fast your wanting to go? is your current suspension gonna hold up to the added ET?

NOVACRAZY2007

yes i'm going to build it myself. the motor is paid for. got it for 500 bucks. my cousin ownes a salvage yard. the 3000 is for the build and swap. i have the chasis already set up with 8 point rollcage.

Welcome to the world of LS Anthony.

5.50 is flying. That is 8.70s in the quarter. You are going to index race running nitrous on every pass? I don't see you running 5.50 index with anything but a 408 stroker. That will not fit the 3k budget.

Anyway you look at it, for 5.50 index, you will need big ported heads, Super Victor and 1000 cfm+ carb, maybe just go dominator.

The way it sounds to me, you can either increase your budget or consider running 6.50 index next season.

How heavy is your car Anthony?

NOVACRAZY2007

car weighs 3028 now but more wieght is coming off. going to slim down to 2800lbs

Heres a pic of my nova

well with 3k i think your best bet would be to go 370ci with callies 6.125 forged rods wiesco 4.030 nitrous domed pistions, ARP Head Studs, ARP Mains, the best heads you can afford, and spray ALOT of nitrous at the built shortblock. i would say atleast 300 to a 350 or more. probably through a progressive. i think your money is gonna run out quick so spend it wisely.

maybe just port the crap out of your heads the RIGHT way and use those and a super vic until you can upgrade to like some AFRs or All Pros.

if you stay with cathedral heads go super vic, and if you go square port i guess your limited to a vic jr, holley high ram, or a nice high dollar piece like the mast intake

and try to get your car under 2800 with you in it race ready. nice nova by the way.

check this thread out. car ran 9.87 on a 175 shot. its not as fast as your wanting but if you do what i posted above you will have more motor, way more cr, way more nitrous, more everything. so it could be possible to hit your times its just gonna be hard.

dont forget your gonna need a engine diaper and all that. and good brakes

yeah i think i'm going to stay with the stock crank with new rods and pistons. do they have those pistons in a 4.005 bore? how far can i mill down a 317 head?

NOVACRAZY2007

I found stock ls3 heads from pace perf. They were like 350 each. Does this sound right?

$314.95 actually.

You can use the exhaust rockers off of your lq4, but you will need to get the offset intake rocker arms.
