This is what I have laying around, so this what is going to be used for a test car engine. The car will not see the street.
350 2 bolt main
.40 forged flat tops
993 stock heads (no port work will be done)
std/std gm steel crank (ext. bal)
5.7 h-beams

Questions:
1. How much NOS should be safe
2. what cam
3. what carb (holley suggestion only)
4. what intake
5. front acc. suggestions

This motor will be used to track test my '82 pro street camaro build. The last experance I've had with SBC engines (for that matter carbs or race fuel) was 10+ years ago.

 

well, ****......
my other 993 is...well.....****. unfixable, junk, etc.. game over.
Ok, I've purchaed a set of sportsman II 200 w/ 72cc that will take the stock valves from the 993.
Please advise with this update info.
Thanks,
Bryan

 

Ok, so two days.....
Are these no answer questions because:
"search yourself"
"everybody should know this"
Or
"we have no ideas"

 

depends on what ur application will be. drag racing engines need different components then bracket racing. a 4 bolt mains would be a better option, but you can still work alot with what you have. with 72CC heads, it will be lower compression. however what u are asking is ver generic. more details would be helpful. There are TONS of parts for a 350, so we need to narrow down this list u ask for.

 

May have confussed people with this: . TEST CAR?????
Did you mean RACE CAR?

 

I guess what I ment by "test car engine" was engine to work out any "bugs" the car may have. Slowly step up the N02 from 50-250 and see how the car works. Something to test with.
There are tons of sbc parts, I guess that's why my question is generic, I don't know. I'm just looking for a cam, piston, rod & compression combo that has worked for other people.

I'd been running 463 bbc inj w/ a Flying Toilet on alkey in my pulling truck and traded my Enderle inj 540" engine for this car. Big power chained to sled going 27mph is a whole different game than what I've just jumped into.

 

Well, here is my thoughts.

1. I wouldnt put more than 150-200 shot, but that is just me. I like to play it safe.
2. Im running a Lunati 41050 cam. http://www.lunatipower.com/Product.aspx?id=1889&gid=269 With 10.4 to 1, Dart Pro1 Platinum 200s, air-gap intake, Im putting about 435 at the crank. Nice little combo.
3. I would run a 650 DP. Nitrous likes a carb on the small side.
4. I love my RPM air gap, but you would probably be better off going up to a Victor Jr.
5. As far as front accessories goes, I would run a low mount alternator and an electric water pump.

your going to try adn run a race motor with nitrious on a 2 bolt main...dont even thing about it...if al you have is a 2 bolt block, take it to an engine shop and have them drill and tap the 4 bolt mains for you. it will make your motor that much stronger
also whats your goal?

if you wanna make a nice street strip car your gonna wanna run any dual plane intake mannifold but again you have not given us any specifics on what your planning to do with this motor.

id use a torker II manifold its good for like 2500-6500 and a nice power band and still dual plane
carb i wouldnt go much higher then a 600, to figure out your carb cfm use this formula

CID x RPM x V.E. / 3456 = CFM

for a cam it also depends on how high you want to rev this motor, pick a cam that meets your power band and power needs, try lunati voodoo sereis they are nice high quality cams

i wouldnt run any nitrious on a 2 bolt maybe like a 50 shot but not much more i wouldnt trust it

as for acc. if its a race motor just run a water pump lol
if its a weekender have some luxieres and run ps, and an altenator and a water pump idk what else to tell you...give us some specifics on what you want to do with this like what type of car your trying to bild and we can help you out a little more

 

2 bolt mains are standard in LT1 engines. It's common for head/cam cars to run 150hp worth of nitrous. Around the 500-600+hp area you can run into weak factory rods. I have no clue what kind of power factory heads will make.

1. 200hp max shot (2 bolt main scares me. GET ARP STUDS)
2. Xtreme Energy XE274H Hydraulic Flat Tappet 12-246-3
3. Pro Systems custom carb. www.pro-system.com Worth every penny!
4. Edelbrock Victor Jr.
5. I run a March Mid Mount Alternator bracket, 6/12 o-clock alternator, Edelbrock water pump with a Moroso Electric drive for it. Works GREAT for many years now. Street and race time. Clean looking setup.

Shoot for a 3000rpm torque converter. It will flash to 4200+ on the hose. It will be making good steam at 4000+rpm. I reccomend a single plane for GOOD nitrous distrabution and the fact that there is no need for off idle or low rpm Torque when you have a 3000+ rpm converter.

Goodluck!
