Future Plans (Engine Advice Inquiry)
I am having issues on what route to take with my engine after the next twelve months....
My current mods are: (Lid, Lt headers, 3inch ORY, no cats, 3inch electric cutout, flowmaster cb, PCM tune, sfc's and stb)
My main issue is: I do not know whether to keep my LS1, bore it to a 383, or just get a 6.0 block...However I do know I want to definitely go with forced induction/supercharger, don't have the money for an Eaton.....I do know I need a bigger displacement for the desired numbers. I want to be around 600+rwhp
{My main concern is reliability and longevity}
What is the best bang for the buck as far as horsepower gains and reliability??
I know if I keep my LS1 I will have to re-do the bottom end probably, is 71k too much?? I will prob end up doing all this in a year and it will probably have around 80k then until I purchase another car for a dd and the end of this summer...I have heard recent great things for the last few years about the 6.0 block
Your help, input, and advice is all greatly appreciated. Thank you
I def agree with you, However 600rwhp is what I want at least..but down the road have future ambitions of being able to up the boost. In the end I really want to build a reliable blower motor

Take your 346 block, send it to ERL and have it transformed into a Superdeck 427 or 440. Put a set of MAST LS7 heads on top and you have a foundation that can take a good shot of nitrous in the future should you get bored with 600 rwhp. While not a cheap build, it will be stone reliable, make great power and most everything you now own will fit including your A/C. Best part is with an LS7 intake, it will look "stock" to the Ford guys.
This is my current plan - too bad I can't afford it now.

If you are set on FI, you really don't need a 427. The new AES 390 short block looks like a great foundation for a FI engine and there are lots of options here too.
Don't forget to save a ton of money for your drive train and suspension - 600+ rwhp will find the weakest point very quickly
Next R&D "bullet" about to hit the dyno.... - LS1TECH
An AES or Kurt Urban 370 (.030 over 6.0), with freshened stock 317's (stock 6.0), an LS6 cam, and a 76GTS turbo, with Kentucky Turbo kit (don't be fooled by the name) will do what you want and be reliable. Your LS1 built for boost will do it too.
Do a search for NicD build thread. His new PB 9.17 post is a few pages down on the FI board. (347 w/76GTS)
You'll need an aftermarket rear axle and suspension with a built T56 and twin disc clutch or a 4L80E with a shift kit at this level. Figure on $900ish for a converter or clutch.
Just skip the 4L60E unless you NEVER plan on slicks or DR's. Maybe not then either.
And another $1k for the fuel system......

Do you think with having 71k miles on my LS1, and itll prob have round 85k in two years when I do this, would it be an issue for future reliability and longevity...Since its an aluminum block over iron
