The stock sleeves aren't capable of stroking to 454, etc. ERL is willing to take my block as a core and sell me one of their ductile iron, resleeved LS7 441's for a nice price. Now, I know I'm not gonna be racing and yes I can do an LS3, etc. These are just thoughts running through my head right now. I'm still debating on superchrged vs. naturally aspirated. An LS3 is still an option, but so is a blown LS7.

Costly option for the resleeved LS7. I saw their price, but that would hard decision to make. Here is a thread on a ERL 441 to give you the dyno results.

The numbers on NA is 662/585 NA

I am way past those numbers with my LS3 418 and the Harrop TVS 2300. I was rather picky on the components, because compstar is made overseas. So my engine builder selected Crower Maxi Light Crank 4" stroke, Crower Maxi Light billet rods, Katech Piston Squirters, and custom Ross pistons. I definitely recommend the piston squirters, and it can be used in an LS7.

The TVS 2300 power is made with CNC cylinder heads, and more porting. I listened to the right engine builders at the time, but there was lot ways to increase power now. Lance Nist of Pantera Efi told me a simple trick with a cam change. Lance does work for Wegner, but is sort of his prototype engine builder. That was one trick that I didn't do on my engine, but I do it soon.


Good luck,

Jeff

That's the way you build a bottom end...

Dang Jeff...sweet engine. I'm a bit envious. Don't know if I can ball out of control like that. Very nice quality parts you have in there too. I'll check into some of those. While I'm going to build a nice motor, I don't have to have the top of the line parts. I'm still gonna save money where I can, because there are a few other things I want to upgrade like a nice interior and an all new stereo system.

Marcus, for the last three days. this is showing that you have replied to your thread. However, I am not seeing anything. What gives?

I don't know....was wondering the same thing as well when it popped up. The only thing I could think of was someone went back in it and voted because there were no new replies.

This is obviously the L-G phantom saying your decision is not made!
