new n/a motor...
new n/a motor... If you were going to build a new n/a motor, only limitation being that it needs to be able to run on pump gas, what would you build? Keep in mind that this will see about 2000 miles a year on the street, and see about 30 or so passes at the track a year. What CI, heads, intake, etc.etc. Not looking to buiild something that can run 8's, but anything less then 11 flat would be kind of senseless.
I think the plan for this year is gonna change, car's gonna sit, while I save $ to build a motor, and the tranny swap will happen when the new motor goes in....

402-408 Iron Block
Edlebrock or AFR 205 Heads (225 's haven't proven **** to me yet)
Fast 90MM
N.W. 90MM T/body
Pulley
QTP Headers and Y thru a stock SS/WS6 Muffler
It makes what it makes....450-475 I would be Happy....
Now will it make it into the SS??????
Who knows...LOL

We'll be talking. All of teh above are a possiblity.. along with the ET heads, and some other intake avenues. Not that it's gonna happen anytime soon, gonna take a while to save up 12 grand.
I would go the biggest ci your budget can handle. Probly a LS2 440ci at 11.5-1 to 12.1-1 with ET 240heads,250+ Cam stepped headers,Carb intake ect.Easy 570-620rwhp =9 second 1/4's.
built right 346ci =10's
big ci -10's to low 9's -streetable.
For reference we have a DD Vette running a 408 ,AFR225's,240's Cam ,12-1 comp. and put's out 530hp/500tq on pump gas.Could probly hit mid to high 500's with better gas.

I'm kinda likeing running mid 10's and looking for low 10's on a stock shortblock. LOL
But I would go one of 2 ways;
1:
Stock LS6 Block
Ultra light weight Pistons/Crank/Rods
ET Heads
Solid roller cam
Fast 90/90
Should be good for 9's fairly easily.
2:
LS2 Block 427
ET Heads
255 .598" Cam
Solid roller
Fast 90/90
Should be a pritty stoud set up as well.

The good news is that the failure wasnt' a disaster like a rod thru the block or anything like that, so what I have is most likly rebuildable. I am gonna talk to the shop and see what they say, try to come up with a plan for something that will work well with the th400 that was gonna go in next month and just start saving up to do that. Worst part is that the car is down for the summer, hell probably for a year at this point, maybe even more.... 
I always laugh when I see people really pushing the stock bottom ends to the limits.. windering why would you even do that, and here I am with one that's got issues. I should have known better then to touch it myself, I'm sure that whatever happened is probably the result of that, but what is done is done. FOr all I knwo it could have just been something that was weak in the first place and the compression was enough, I don't know, won't until it comes apart, but at this point i think I am gonna ty to get the car back to my parents house where it gets stored all winter and just sit back and try to figure something out.
I really wasn't ready to build a new motor at this point, I was hoping what I had would stay together for a couple more years so I'd be able to finish teh car with all the lightweight stuff, etc.etc. but fate didn't see that happening I guess.
Sidelines for me this year... but I guess it will give me time to build the garage myself, so I can save some $ on that project anyway.

Gonna talk to the shop today, see what they think. As much as I'd like to just rebuild a 346 and stick it in and go, I just feel like that's a waste as I know I will be looking for more in no time.
Gonna suck having the car down for probably 2 years, but at least when it's done, it's really gonna be done. I mine as well do all the lightweight **** and whatnot while the motor's out, my garage at my house will be up within 6 months, so once that happens, I'll just push her in and start going to work... once the engine's out, mine as well work on all that engine bay stuff lightweight everything, etc.etc.etc. Gonna turn into a long work in progress now I'm sure, but when it gets reborn, it will be a new beast for sure.
I'll have an old parts pile that will rival noyzee's and evil's by the time I get done changing pretty much everything now.

well... at this point, I'm either leaning towards a 408/414 CI iron block.. but with teh time it's gonna take me to get the $ together, world stuff will be readily available by then... so maybe I'll just go for the gusto, a 471 world motor Regardless which route I take, I figure that it's gonna be a 25K job with teh rest of the car's suspension, cage, and all the other crap that will end up getting done before the car ever sees any use again... so the world stuff, may be a viable option.
I wonder, what kind of HP can we really make all motor with pump gas.. guess I may find out in about 2 years

On another note, has anyone seen/tested the trick flow heads yet? any resutles, flow bench, dyno and track? If I do a 408 motor, those, afr's and possibly looking into reworking my ls6 heads if it's worth while.
I think the goal is gonna be 520 to 550 rwhp if a 408 is the route I take. I really don't want to add the iron block's weight to my car, but it's a heavy pig already, mine as well add some more.

jason sorry to read of the engine prob that really is a shame what with all the great work and parts that car of yours has in it, **** luck is what it seems to me.
dont you need to establish a budget before anyone can recommend an engine configuration? so what are we talking about dollar wise that you are willing to spend for the complete engine parts and labor?
meanwhile you should get a summer beater for the dragstrip i see lots of cheap camaros and firebirds pop up in the paper, its better than nothing and could be a lot of fun to beat up on a $1,000, 150 hp camaro for a summer. you'd still beat most of the cars on the Pike right.
btw, i emailed you sunday before you problem, i had a preminition you were going to have an accident and i advised to be careful......my crystal ball isnt tuned in right now but when it's working again i'll let you know what i see.
last question: Grundy.....can they cover this? i wonder.

onr of the pistons on teh passengers side, #5 and #7 plugs were black, but oe on teh passengers side looked like black gold form the beverly hillbilly's
Looking at a 408 setup, I figure it's gonna take a while to get the car back together, so I can contemplate 100 setups a day until I have cash in hand.. but I figure that if I can keep it under 10 grand including the needed fuel stuff, and the intake and bigger headers to go with it I'll be o.k. So much for making the car lighter, looks like it's gonna gain 75 lbs from an iron block now. Still not sure about exactly what I'll put together, but something that is south of 500 rw on motor thru the th400 sounds good to me right now, should get me to where I wanted to be in the end with the car anyway.

Wow that sucks. It seems like **** always happens to the people that try to take extra precaution. Murphy's Law. Sorry to hear!
With the amount of technology that advances every season, I don't know why you are even worring about it at this time. Just going to give you a headache when you will probably end up using something else 2 years down the road. I think in the future when I have money I will be changing my car, but that isn't for 2 years + so I don't even think about it

If your stock block is still good why not go with a forged 383? Should eb able to make close to 500 rwhp NA with the right intake, heads, exhaust, etc and then maybe a little spray for the track. Would def be a stout combo and not break the bank. However if your going to go big CI id say a ls2 stroked out to maybe a 427 or larger. That way you save the weight from the iron block and still make well over 500 rwhp na.
