Looks like my post got deleted, too much shamless plugging it seems.



Umm... Thanks for... ? What did I do now? LOL

Eric McClellan is my real name, Max is my sons name. I've had this screen name for probably 20 years... so it's kind of a family name

This is alone the lines I was thinking about, if I was to do this, because of the Tranny I currently have (and the money tied up in it), as well as the Fast 2.0 system I recently purchased. So I should be able to just get a LS engine with a carb intake, headers, mount, and a tranny adapter, and all the front accessories, and the brackets?? I would like to have a combination set-up that will make at least 500 to the wheels?

To get 500hp to the wheels (rwhp) then you need a stroked LS3 418. LS418 makes around 645 or around 515 rwhp. The other poster is talking about fwhp. I recently talked to Brian Thomson (Builder of Stielow's engines), about FAST being used with the TVS2300 (I have one for sale), but he said that FAST ECU can be used with an LS engine. Although, he said that the LS ECU are more reliable than aftermarket.

This is now on track where I want to be. So if I can build a LS3 418 I should be in the area where I want to be.. You lost me about the Fast being used with the TVS2300?? Also the LS ECU is more reliable?? Would that be the FAST I have?? and whats the TVS2300? With the LS ECU, would relate to having it programed correct? The Fast System I have is more of a self learning, but can change basic things to it. Back to the LS3 418, what type of heads (stock?? LS3), sorry for the 3rd grade questions, but I'm in elementary when it comes to the LS side..

OEM parts from GM have much more testing done on the parts, so they don't fail as compared to aftermarket parts. For example, my 2000 Silverado uses LS ECU with 24x reluctor wheel, the engine has 140,000 miles on it. Never been serviced for the ECU. I doubt if you get that mileage out of your aftermarket ECU (FAST).

I have my Harrop TVS2300 up for Sale, and a person asked if he could use it with his FAST. So, I talked to Brian Thomson and he said that it could be used. Although, he said that LS ECU is more reliable. The only disadvantage is that you have to hire a custom tuner for the factory LS ECU to set it properly.

The best heads is the LS3 or L92 style heads for an LS 418.

Well, I'll be the one to say it - keep what you have and just drive the wheels off it.

In the lsx vs small block thread you said it runs 10.6 quarter miles. And now you want 100 more hp. It doesn't make any sense unless cost is no object to you.

I love the lsx platform, but you are talking about spending a boatload of money for an extra 100 hp that won't make a bit of difference on the street.

An lsx does do everything better than a gen 1 small block, but unless you are really stepping up the hp number, ie to 600-700++, there is no reason to throw out everything you have now.

When your current engine needs a freshening, no question - go lsx. Or by then, the new direct injection platform may be the hot ticket, and an LS3 might look as current as a TPI engine does now.

Not really true I have a stroked 383 LS1 that made 496 rwhp.

Here is the thread that I pulled the dyno numbers. There is actually several on the L92 418. Dyno numbers will vary on several different factors.

Although, if you do a supercharged LS 418, then the numbers will increase. My LS418 with Harrop TVS 2300 at 15lbs of boost was around 691 hp @ 5200 rpm and torque was 787 ft/lbs at 3900 rpm on the engine dyno.
