how to carb an LS series engine

The Ram Air 5 400 was a unique block.
1 guy used one in past. Boosted to 1500 HP.
Just its a $10 k block to buy today.

The Crower Ti rods I have are rated to 2000 HP.
Other set of Crower forged good to 900 HP.
 
Pretty much back in the day Phil, when Grumpy was growing up...
nothing but factory Iron parts....just kept adding boost & Nitro.
8's the goal.
Only Beswick was sucessfull longterm.
 
if money is no object then having a hemi head does alot in way of making power and preventing detonation.

for the rest of us we just have to be sure we know what the F we're doing. only a couple things i dont like about iron heads:

1. theyre heavier than aluminum.
2. you cant really repair them if you fuck them up like aluminum.

ill take a picture later once this stupid rain stops of a combustion chamber i got in the shed that looks like it was peppered with bird shot... that head is still easily fixable and reusable.

heres what i know to be true about "this motor can only take X horsepower" arguments:

1. if the tune is off, motors gonna give somewhere, detonation is a motherFer
2. if the motor that can allegedly hold 10,000,000 horsepower is not assembled to exacting clearances, that shit gon' blow. (and i usually see this with either hydrolocking or valve to piston contact) grumpy preaches measuring everything over and over because in a low hp (under 600) application, having shit clearances is leaving power on the table and in a high (over 600) hp motor you are basically hurting the life of the motor and hurting your investment.

i've mentioned other places on this forum my good friend who took a stock L series datsun motor to places people literally said "no you cant" with a good tune and rpm control. 26-30psi of boost with a paper head gasket is about double what anyone said was possible. then he did it. then everyone who claimed it was impossible just started calling him a liar. so he started taking their money in street races.

what i mean to say with that story is that everyone is a critic, and as you build something if you believe your science is right, fuck what everyone says is "possible" or "the limit" hell, back into the LS topic, when damn 4th gen camaros were everywhere no one could boost a LS1 with a procharger over like 7 pounds without fucking something up.... now guys blink and 17 pounds is holding steady on the gauge. someone just had to break the barriers to shut the nay-sayers up .

Aftermarket Aluminum Poncho heads won't hold up under Nitromethane of 10-90% Phil.
Its been tried. Blown out combustion chambers immediate.
Too much peak cylinder pressures.
Only Vintage Poncho cast iron holds up to Nitro.
And Ultra Rare Mickey Thompson Hemi heads made fore a Pontiac V8.
Cast iron can be repaired.

yea but my point is you shouldnt need nitro to run 8's in a <3500 lb car... all the science is readily available for you to do that shit in the aftermarket what used to be impossible only because the parts didnt exist
 
My CROWER Ti Rods came from a Nostalgia Super Stock Racer.
Even the piston wrist pins were Titanium.
Money no object. $80k engine build.
$300k Race car.
Guy was broke.
Right place at right time.
Lots of stacks of 100 Benjis handed over.
Ti MINE.
