Get a 572" BB crate motor almost 800FWHP on pump gas and then get the driveline.

 

Only the 602hp GMPP 572cid motor is pump gas, the other one is race fuel.

 

The 12.0:1 motor will run on pump gas too M1.

Hot Rod had an article last year where they knocked ~5º of timing out, installed a knock sensor and made a dyno pull with 91 octane. No detonation audible or otherwise and the engine made close to 790 hp as I recall. With a few cooling system upgrades and a fatter a/f ratio, I have no doubt the thing could live on the street.

-Mindgame

 

MG is right.What a memory.
That HOSS didn't loose much at all to pump gas over the factory spect's. The 12-1 one made more than the factory spect's.
That's 647RWHP with an auto(Turbo 350 or Glide) On pump gas,with the option for MORE.

 

Ho Leash It!!

"$1000+ for intake"...does this include rails, elbow, EFI conversion, and TB?


"$900-$1000 for valvetrain w/out rockers/shaftmounts." I'm assuming the camshaft is in there?


"$700-$1000 for machine work on the block"...exactly what all are we talking abot here? just basic machining for like a 355?

Would some top of the line AFR's be enough head, or would converting some SBC's be necessary?

Bang for the buck (wise), it looks like staying with a good set of LTx heads, a ported intake, damn good valvetrain, and a custom cam is the way to go. And just settle for 450ish rwhp. I dont think it would be worth the extra "cabbage" for the 50+ rwhp you would gain!

 

The 540 BB has caught my eye MORE than once, i admit! If it just wasn't so damn hard to swap everything out and work on it...

 

The 572 comes with the Generals warranty,too.
That 540 don't.

It's not that hard of a swap.Headers are a big thing but several people make them.Working on it HAS to come under the title of "a labor of LOVE"

 

True...

For some reason, i just dont wanna do a BB. Guess i dont wanna hear people mouths about how it's not an LT1 or whatever. Which they'll be saying the same thing if they see a single plane under the hood!

 

Tell them it's a LT-2 and they will be out with these next year. Yours is experimental.

 

hahahahaha....I almost spit my drink out!

You know, some of the dumbasses around here would probably believe it!

Damn...I'm still laughing!

 

Yeah the elbow is what makes it push the $1000 mark, but you can use the same TB you have now.

Yeah cam, lifters, pr's etc... for a SR

Well, balancing, bore, tq plate hone, zero deck, cam bearing install, cleaning are the basics.... Now when you add installing 4 bolt caps, line bore, line hone, lifter true and lifter galley and main cap oil mods you add things up here.

A well done TFS or LT4 casting would do it (all though the LT would cost more to get to the TFS spec) 295-300cfm can do it but expect to pay $1600-$2200 for a ported casting without parts

A set of 215RR LT castings is not cheap. Bare ones make you want to look for good SBC castings and convert them (which some places can do this cheap now) A CNC ported AFR 215 is over $3000k without parts.

For me.... the $1000 set of 18X I saw on ebay with conversion to LT1 and some porting would be a steel compared to AFR RR's

Oh now don't forget valves.... $240-250 for a set of Ferrea 6000, $350 for Ferrea Competition Series Valves and $700 for Hollow Stem Versions.

Springs, Ti Retainers, locators, shims, locks, seals, setup, assembly, flow tests and lapping....

The one I'm working on now...

396 cubes: H Beams, Dragonslayer Crank, Custom Pistons
Race preped block: bushed lifter bores, 4 bolt conversion etc...
TFS Heads: Stage 3 Meaux Porting, Hollow Stem Valves
Super Vic Single Plane: Ported to match heads
Hyd Roller Valvetrain: all the good stuff ;-)

It's for a street car with a small 2800 stall. Tame idle and built to live a long time and take on a new ZO6 in a 3500lbs car. Some of the same tricks in the LS7 I'm using here without all the Ti. I get the advantage of no OEM limits and emissions.

I'm working on a bolt in 388 cube crate motor... just talking to some people about short blocks and heads now to get exactly what I want. A SR will probably be in there and both aftermarket and stock castings... trying for a economical street high 400's-500rwhp for $10K or less.... Might be tough but that's the hope.

Those things ain't bad for the price!

Tell um,Yea man check with your dealer and if they deny it,keep checking back. The General won't put this out until the last minute.. He He

 

Ain't as bad as a 706 but pretty bad for the street.

 

I always thought it used a round TB, like the LS1?

Damn....1000 bux?!?! Didn't those things flow within "less than 10cfm's" ofthe CNC ported ones?

What do you expect this one to make?


That would be sweet as hell!!
