ok iam looking for 400+ hp 1100+ ftlbs torque

what you think

i have whats in my sig plus a few items on the bench going in in the next few weeks.

got
goerend converter
he351 with 4" downpipe
some more pump tuning
reset on valves
bump the timing some more
cooler tubes
powerstroke intercooler
changing to a amsoil filter with some sort of cold air intake.

 

300 +0/-40

 

Thats an awsome truck.... I think if you spray some w/m you could be getting close, but without maybe 325-340 hp and who knows on torque its harder to guess than hp, maybe 800-850

 

Pretty sure your going to need bigger injectors to see those kind of numbers. I don't think at 400hp your gonna see 1100 ft lbs either.

 

255/660 is my guess

Are you going to go dyno so we know what it actually is ?

 

254hp-569ft.lbs on a dynojet.

maybe less if you have a junk transmission.

what kind of fuel supply do you have?

 

I bet around 290-320 hp, and about 700-800 ft lbs.

 

agreed, and the only way your going to see close to 400 hp with that turbo is if you advance the timing a lot. Then your not going see even close to 1000ft lbs of tq. Your going to need more air and fuel to see the numbers your looking for.

 

You'll need more fuel and air.

 

ok so more air an fuel...

i will dyno it in the spring at dyno days at bd if its not stupid busy

will the he351 support 400 with enough fuel..or egts going to be stupid??

 

I got a 351. It doesn't get hot. But it gets way out of its map range!

 

Not on a ve pumped 12 valve with an unported head. Three whammys against ya!

 

If i made a guess it would be 250/600 my sons 91 hits 407/900 with PODs / twins and w/m EGTs stay at 950
you will need more fuel and more air to get to 400hp

 

****...at least your honest

i should have bought the blown p pump motor i found for $700


before you send me to the search button
point me to suggested inectors...

industrial injection??
dynomite diesel stage III??

90-100hp with a little w/m if the egts get too high.

i tow alot 8000lbs plus.......i will keep spending money till i can outpull all my buddys newer trucks with the chip

but not tell them the mods

 

Are you getting your power to the ground yet?

Personally I'd leave the engine alone and think hard about what you wanna do about your trans. Build your 518 and put a converter in it......Swap to a Rebuilt 47RH lockup and put a Converter in that and have lockup but you gotta find a 47RH core and stuff needed to swap.....Put a shift kit in the 518, converter and wait for it to blow??

Or go to a 5 speed manual......

If you tow 8K I'd build your trans and leave it alone Otherwise you're gonnna have to drop dough on a turbo and airflow upgrades. 8k+ is alot of weight for an Overfueled 12v. You're gonna be on that W/M button like flies on poop trying to keep them under control.

BTw, your truck looks awesome.
