Look for EXAMPLES, AI has several cars making 500+ at the wheels NA even through non-lockup converters.

I would NOT be looking at a 396, or AFRs either. Solid roller will be a given at this level, sure it can be done with hydraulic too but at what cost???

 

you guys are really getting ripped off! I just checked current prices, I would gladly sell those parts for $8k!

This is exactly what I am talking about!

 

Oh yeah, and an MSD Opti.

 

yeah i thought afr's were the best but i gues the tfs pieces are on top ?

 

500 to the wheels?

Forged, studed 383, solid roller, ported stock (or aftermarket castings), the usual
supporting mods (including a proper tune); call it a day and run a 250-shot to your heart's content.

500rwhp on solids is not as uncommon as you might think.
500rwhp on hyd is going to be a bigger challenge, but it's doable.
I don't advise making peak HP your goal though.

Remember to upgrade the fuel system and read end so you don't break anything.
Consider a trans rebuild/upgrade while you are at it.


Do you need a 396? No.... it'll just cause you more headaches than gains over a 383 (personal opinion)
Do you need AFR castings? No ... but ported aftermarket castings sure do make filling those cyls a hell of a lot easier with a big cam.
Custom grind? .... seems like a wise investment to get the most out of your setup, but certainly not required.

Good luck with the build

 

assuming you can get the parts for $8k, will it throw itself together? forget about the nickle and dime stuff, but $8k is a bit optimistic. I get your point about buying right instead of buying names though...

 

so is the 383 just safer due to thicker cylinder wall for a big shot? the cars already got a cpt race built 4l60 and a narrowed 9"

 

The difference between a 383 and 396 is stroke.
The longer stroke "compresses" the power curve, which allows you to run a bigger cam without revving to the moon.
But the .100" increase between a 383 and 396 has very little effect there.

Longer strokes expose more cylinder wall (closer to the edge of the casting) and require
more block machining (breaking into the water jacket) and possibly having to machine the rods to avoid the cam.
Neither spells instant death, it's just a whole lot of hassle.

If you WANT to run a 396, go for it. Just don't expect it to be a huge improvement over the 383.
There are guys running 4" strokes (408CID) and doing just fine.
(The 408's stroke is .250" longer than the 383's; you see a huge difference in the curve)

Make sure that you stud the mains (2 or 4 bolt) to contain the pressure created by the N20.
The last thing you need is for the bolt to stretch enough to allow a spun bearing
Studs use the stock coarse thread to get into the block, then a finer thread to allow better clamping force.
I'd do the same with the heads.

CPT does excellent work, good choice
9" should do just fine.

 

give me 12 grand and i'll send you this turnkey....



made 486 RWHP thru a 4400 stall converter and a TH400/9" combo... Put a T56 behind it and you're talking an EASY 530-540 RWHP.... The 486 was a very conservative tune with a lazy cam (motorwise) that RIPS on spray....

Car just made 822 RWHP spraying it.... 11.5:1 AF Ratio and gorgeous plugs after the pull too.... and we haven't pulled out the BIG jets yet.....

like others have said you can throw parts at it but a car has to support BIG horsepower so when you say dream LT1 you have to budget for dream fuel system, dream tranny, dream rearend and dream suspension.... don't forget dream cage that will save your dream *** if you put it into the wall at 150 plus... This car has complete fuel system 83lb injectors, FAST XFI, etc..... TH400, 9", 12 point cage, window net, etc..... all that **** adds up quick... you can build a motor like this for cheap but you'll drop it in a death machine if you haven't budgeted for the rest...

 

You mean you can't just bolt on the holey grail AI heads and run 8s? that's what I keep hearing


Shoot me a call man.

 

id like to make 400horse overall how hard would that b

 

put that on hold till christmas, christmas 2020 that is. j/k whats the gas mileage u get in that just wondering

 

400 to the wheels is very doable with heads and hyd cam on a stock bottom end.
Nothing extreme and lots of very streetable setups out there.

LMAO

Yes, every one of which is doing so with a solid roller cam, not much of a challenge in that.
Not to say Ai doesn't make decent stuff, but (as TwoFast4Lv pointed out) it's nothing magic.

 

If it is so easy list more examples. I know there are other examples, I can think of a few specifically but why don't you enlighten us?

 

Just please stop Ellis, we all know your dream sets up is a set of Macs and a LT4 hot cam...

 

heheheheheh..... no AI needed, i've got CSMRE power under the hood.....

pm me you # again. my cellphone shot out of my pocket on a rollercoaster... it's permanently MIA....

probably like 5mpg..... maybe 7-8 if i mess with the XFI a bit..... i really don't know tho for sure.... LOL!

 

When your car is as bad *** as outlaws, you dont care about gas milage anymore!!

 

My dream LT1? Well as long as we are dreaming....think you can make 1000 hp on pumpgas? This might get there.

383
SB2.2 heads
Matching intake
Hyd roller
Monoblade
4340 bottom end
9 to 1 comp

AND a 88mm turbo, WOW would that be fun or what?

But, 500whp with a stick or an auto is two VERY different animals.

500whp with an auto DAMN sure aint happenin with 8 grand. Not all motor anyway.

 

Haha, best reply in the whole thread.

 

yes I had that dream....then it was brutaly Violated by the wet dream I posted
