Both ways can get you there: high compression stock cubes or stock compression with more displacement.
The OP was looking for an NA SBE LT1 600rwhp build on an automatic. It can be done, but that recipe requires some ingredients that the OP does not want to use. I also get a sense of some denial and false hope that an LT2 intake and LT5 throttle body could ever flow what is required for the OP's goal. Sometimes you just have to see it for yourself I guess. |

I appreciate the input from all of you guys. I KNOW a whole lot more about a boosted application than I do about NA so this is helpful.

Everyone builds differently and your right compression will get you there. But, my build Nitrous is my Ace in the hole.

On an aggressive heads cam setup the lt2 will be more than 10-15 hp behind a ported msd. Probably around 30
The 95 tb will be fine IMO. Not leaving much on the table with that in the 6-700 hp range |

Compression EFFECT
Quote:
Running E85 should provide enough octane to support that compression level in my case. No doubt you would probably have to run 100 octane if E85 was NOT available.

You’re going to be in the 540-550 area with that setup. Also the higher you go with compression the less gain you’ll start to see. You can run 14:1 on pump E with no issues.

580-600whp has been achieved several times with a ported MSD on E85. RPM has at least 3 cars now, Pray Performance has done several...GPI has some too.
Ported MSD Ported 95 Good Heads(FED/Pray/CID) Compression bump (12.5 ) Stage 3 cam (230's on the intake) E85 Proper tuning You need more compression with larger cams to gain back some low end efficiency since you lose a lot of dynamic compression. This is what effects tip-in throttle and driveability. It also nets more power...with E85 compression can be raised quite a bit, but you have to be careful how high you go if you ever want to run pump gas.

Hennessey, Lingenfelter, KaTech and others have answered such questions long ago. No need to reinvent the wheel, just hire the expertise.

one thing to heavily consider is that peak dyno numbers don't tell the entire story on performance. i don't think a ported stock cast cyl head and LT2 manifold is going to get you anywhere near 600 on a legitimate dyno. how much are those heads milled? what gasket are you planning on using? stock valve? quench? edit: do you care to share the cam specs?

For instance it is NOT a good idea to use a higher stall speed convertor generally in road racing applications because you dont want to affect the shifting characteristics. The A10 does a wonderful job in TRACK MODE in making sure the car is in the RPM power band. RARELY even on slower parts of a road course is the engine rpm EVER below around 4000 RPM. Higher stall speed convertors inherently have more slippage built into them which is great for drag racing to help get the car off the line faster but it is not something that is desirable in my application. The slippage results in higher tranny temps as well. I am rethinking the CAM selection but I will post it up here along with the DYNO when it is installed.

Don't know where you got that. They all build primarily street cars for all types of track applications. Look at https://www.lingenfelter.com/events.html for example.
