thats the advantage of spray, maybe one of their ultrastreet motors with a plate.

Quickin

I love it....and you get a 2yr/unlimited mileage warranty with that 1,000 HP pump gas bad bitch. Now thats builder with confidence in his engines. He sells it as a STREET ENGINE too

but with a big shot I would have to worry about race gas and refills.. i think im leaning more towards the procharger 540 since it will be "easier" to handle in its street form

i also dont have the funds to buy a motor outright... its more of buying a couple parts at a time..

Quickin

Whats your budget?

I know, isn't it nice to hear people on an LSx forum tell you not to use one, it shows we're not just BS'ing you.

The LSx is great, but its not as good as BBC, and NEVER will be.

No you don't. There are dual fuel intakes with 16 injectors that are fed from a stand alone tank with race gas for when you hit the nitrous. Drive around all the time on pump gas and when you're ready to hit the nitrous your timing tuner will drop the timing and you're rewady for the funny button.

The best of both worlds is here.

ahh always something ha... its a tough call but I just think the 632 wuld have way too much power to be enjoyed on the street.. I wouldnt even be able to play with the throttle... 540 built for a procharger wuld have "only" about 650 hp in "street form" as compared to a home built 632 havin about 850 in "street form"


as for budget.. I havent punched numbers yet but its more of a long term project so im in no rush.. If I have to wait a couple months to save for a better part I will.. I will prolly drive the car around without the blower for a while and then bolt it on when I get the funds. I guess you can say however much it costs to build a n EFI procharged 540 will be my max...

Keep in mind you also have to beef up the drivetrain, so add another little chunk to your budget.

ha ofcourse.... money pit

I don't know man, my friend has a 1200+ RWHP Viper and he has alot of fun on the street. Either way, on the street, you will never be able to anil it from a dig no matter what tires you have...without spinning. So you might as well have it on tap for those rolling races.

NRE makes those dual fuel intakes to work up to 2,300 hp Twin-Turbo small block 454ci's.

man u guys are good... throwing be back and forth between both combos.. what is involved in a dual fuel intake with a seperate tanke for race gas?

2 fuel systems, and a $3000 ECM

Quickin

8 more injectors, a fuel pump, lines, and a fuel system like the Electromotive lap top programmable. You need a kickass fuel management system like this anyway.

that seems pricey... I would also have to factor in all the bottle refills.. with a big shot refills will add up quick.. i think id rather put up with the bigger initial cost of a procharger and always be able to add an intercooler in the future and dial up the boost.. i think a procharger sitting on the side of a big block just looks dead sexy..

while we are on the topic of ecm and fuel management what would you suggest with a budget in mind... ive looked at FAST and ACCEL DFI so far...

Quickin

Big Stuff 3...I think its around $3,000. Electromotive is also very good, don;'t know the price though.

Might want to ask thois in the "PCM" section.

Another builder FTM (Fast Times Motorworks) builds a BBC, I think its 598ci and a Procharger at 6psi. 1,000 hp. He told me if I want for $3,000 additional it can make 1,500 hp., upgraded blower.

wasn't W2W going to offer a complete kit for the 16 injector setup? I know Kurt used it on his Nova.

And Steve morris racing engines makes a PUMP GAS 1200HP procharged 572 for 24K.

I don't think a F1A will support 1500 hp. When doing a FI engine, the blower/turbo will determine max power output. A F1A is only good for around 1200 hp IIRC.


Granted, the ultimate power potential is higher with a BBC. The OP wanted to know about for 1000 fwhp. For that hp level I wouldn' build anything but a ls.

lsx block 427 with the F1A/C/R. Correct internals, correct builder. It will be dead nuts reliable, and last a long time. JMPO

Shafiroff BB gets my vote.
He's been around for years - with a great reputation.

Keep it simple. Carbureted. Simple fuel system. Gobs of TQ and HP.

Drivetrain and chassis??

im pretty set on a 540 with a procharger for simplicity as opposed to a 632 with a NO2 shot with separate fuel tank and 16 injectors and all.

for drivetrain i plan on a worked T56 or the Gforce T56.. usual beefed up rear end with axles with a form of trac lock with 3.50 or so gears.

for chassis ill do any kind of weld in or bolt in stiffeners or connectors i can find.. new A-arms and all... for the rear no sure if im gonna stick with the stock geometry or go for a 4 link...

Quickin

The Procharged BBC would be sweet....but to do 9's like you want the 632/1000 will do it without nitrous, with ease. If you want some more power, just put a 100-150 dry shot on it and maybe go 8's.

Then pull off the track and drive it 150 miles back home on pump gas with no problem at all.

Decisions, decisions....woo-hoo, it'll drive ya ****** NUTS!!!!!!

I've been in the same boat for almost a year with what the hell I want to stuff into a car next. I drive people CRAZY around here.

But ya gotta keep asking and driving everyone batty if you want to get what you really want in the end.
