I am beginning the parts gathering for the Single turbo LS1 build that will be put into a '74 Datsun 260Z with an independant 8.8 rear. I am shooting to build an engine capable of 750WHP. My plan is to do Rods, pistons, cam pushrods, oil pump, valve springs, head studs, and maybe main studs(although I'm not sure this is worth it) I do have a set of 317 heads, but with pistons, maybe the 99 LS1 heads will do?

Where do I start with these part selections, and what have you been happy with? Is this HP goal realistic?

I have heard alot of folks go with the AFR 225 heads. Those can put down some impressive #'s at high RPM. Wih aloy of boost and low compression and a cam, you can totally do it. I'd shoot for a cam in the 240's though. It wont be a street car though...

What would I search to look that up? I went through many of your threads started, but only found tidbits of info. And mark what would guys with 600 plus thread replies do if everyone searched and found exactly what they were looking for? Nitro it looks like your combo may be what I need, if I can find the info. Thanks Chris

Just make sure to go with a small cam and quiet exhaust, and you should have an outrageous sleeper. I can see the z06 and porsche owners thinking WTF just passed me?

wow, thats aweful helpful of you.

Attention everyone, may i have your attention please? No one post anything asking for opinions or advice. Just search. Spend 5 hours reading threads that dont answer your question and arent directed to you or your needs. And then even when you do that and then post, we can have people tell you to "do a search".

if he asked whether a maggie or procharger was better, thats one thing. No need for the search reflex comment here though. DOnt respond or read the thread if it is worthless. People will stop when they go unanswered.

It's realistic for sure. You need to use an engine builder that knows what they are doing. Do some browing in here and in internal engine and go from there.

Agree. The shortblock is the most important part, so find a builder that knows what they are doing.

Do you think it would be less expensive to buy a short-long block built for boost, than build my own? I have been toying with the idea of just buying an engine already built, but it goes against my way of doing things. i have always built the engines I have in the past myself. But the one thing I havent accomplished is 750whp, as the most I have is 560, and that is a stock 5.0 t66 Ford.

I have 6 Ls1's ( 2 complete 4l60E, 2 complete T56, 2 long blocks) and was going to take one of the running longblocks and build it myself. This is all assuming that I can save some $ in the process. I was thinking of doing a stock bore, freshened bearing, shortblock with rods, pistons, cam, oil pump, and either using the 317 heads, or purchasing some aftermarket heads (using head studs) GM MLS head gaskets. What do you guys think, am i tripping over a dollar to pick up a dime? Should I just bite the bullet and go with all new stuff? I havent really priced it out either way, since there are so many ways to go, but i think it may be quite a bit less expensive going the rebuild way.


Let me know what you think, and I appreciate your input greatly.
