346,370,420,417,427ci?
Well, looks like I'm building a NA car too.This will be on a budget of fairly off the shelf parts.I'm also between a 6 point or 10 point cage/roll bar.
Should I just go huge Cam 346 or go cubes?I'm thinking the 346ci can make around 550rwhp which should bring in low 10's high 9's NA with the race weight of this car.Bigger cube should be 600-700rwhp depending on setup.

what is the car going to be? weight, tranny ect?
i like the idea of the small cube, but big cube is just a tad easier, and with cubes and compression you can go bigger cam, and better heads.
its hard to say, the small cube will also save alot of weight over an iron block, will the cubes make up the weight? thats iffy.
i went big cubes cuz i wanted the lsx block, i personaly would never build a basic iron motor, i like the idea of a nasty *** 402.
little more cubes, and still light weight alum motor.

Also,why not a basic iron block? They've proved themselves over/over to handle power,expecially your level.Obviously the LSX is stronger but I bet you still pop gaskets
Chef- if we ran it on your dyno it would make it Mine probly won't

That with a good set of AFR's or ET's,250+ duration Cam,carb intake ect can make the power but will rev to 7500-8000rpm. With the right gear,tranny it should do fairly well.Also thinking Morel hydrolics with a rocker spring kit to be alittle different

as for the iron block, to go from a 402 alum to a 408 iron you gain what 5 horse power but gain 100 pounds plus the extra heat of an iron block.
to me, ls2 block 402 is way better then iron esp in the setup you are trying to do (cheep, strong and fast) 100 pounds on an na motor is worth it.
i wont pop gaskets, im not spraying. lol just baby shots.
i havent poped a gasket since i found the secret head holder downer flux capasidor, flibbist valve

346 all out setup would be killer but dont you still have that other iron block hanging around still?? that could work real good too no? and go 10 point because you know by the time the cars done your gonna need it regardless

Nothing says worth dealing with like proven times and setups.
If you wan an odd ball motor try the 370, i've seen alot of people do them with good #s, but not as many people know about them. Cost isn't too high either.
That could be another thing to help people will be like a 370? You can then talk to them about it, and possibly snag a customer.

The only reason I'm doing this is to show what these motor's can do up here.We have a ton of built cars but no one is a serious racer.This car will be built to race only
Then,soon my other car will be ready.That is more of a "out of reality" race car.

A 346 would be a great showcase for the shop and the potential of these factory motors. Plus I am very interested to see what you guys could cook up w/ a max effort ls1.
Personally for the money and performance, seeing that you are staying N/A. My vote is for a Alum. 402 (nice squared motor), big cam and some ETP or Trick Flow 240 heads and about 13-1 CR. L92 looks interesting but, I'd probably go w/ the above.
What I'm curious about is the tranny selection. I'm assuming you're gonna go auto, even though that's *cough* cheating *cough* according to some of you guys. I say TH400 w/ a brake if you go more cubes and 4l60E if you stay at stock cubes, I dunno how it will take 7500+ rpm pulls though.

hey, im a raceer!!!!
an all out 346 would be fun, anything all out NA will be fun, im already lovin the new setup. i havent even looked at my car since saturday, and if i wanted to go race tonight i could.
im lovin it.
i am planning on a touch up of the tune befor friday, then logging and see what we can do, but 10.4 at almost 130 NA isnt bad with the intake, heads and gearing i have (i may go to a 430 gear, 3:73 + glide + 7800 rpm just isnt the right setup. lol
love the na thing tho with small spray
