Ok so now that im confused as hell and wasnt really clear about what i want in my previous post I currently have an LS2 block and an 86 I-ROC. My goal is a 550-600 hp driven on the weekends raced about 40% of the time. I would like to know how to achieve this goal and which route would be easier/more cost efficient: Sticking with the LS2 or selling the block and going with the LS3 shortblock from Texas Speed. From some great advice im leaning towards LS3 im confused SOMEONE HELP!!!!!!!

I'd just go with selling your LS2 block and getting the LS3 short block from Texas Speed. No replacement for displacement and the LS3 heads would flow more air through that LS3 short block.

Thats what i was thinking. I do have ported LS3 heads and intake ready to go but i was told for that amount of power get different heads and intake.

Ls3 has the 4.065 bore you'll need and a 416 with a Mast head or TSP's LS7 small bore head will get the goal your looking to get.

Just want to make sure the LS3 is the most bang for the buck and the extra $ spent is worth it

Definitely would go 416... what I plan on doing.

If ur LS2 is stroked already with the 402 package, I would stay with it. I am only saying that because u used the phrase best bang for the buck. If its just a LS2, then sell it and go with the LS3 shortblock. Hell get crazy and just get the LS7 short block with ur LS3 heads and watch them shine!! Think very carefully what u wat to do, it is going to cost money to build the shortblock to the long block. im assuming you dont have an LS engine to remove the other parts like the valley cover, oil pan, etc. If this is true, fork out the cash and buy the long block or the complete turn key engine packages some sponsors offer. Just my opinion, something to think about.

Alls i have is the LS2 block and port matched heads intake. I have someone to buy the oil pan from and stuff. Thinking about it it might just be easier to buy EVERYTHING from texas speed (except the tranny) and hopefully theyll package it up and hopefully give a good military discount right? I have a limit of $25gs for my total project but that includes a moser the LS conversion kit (3rd gen) and tranny.

What heads do you have now? A 402 LS2 based engine with killer cathedral port heads (TFS/AFR 235-245) should be able to make that power.

Sounds like you havent sat down and really calculated out everything you need. If all you have is a short block you are going to need at least a couple thousand dollars of misc not including heads...... Hope you have plenty of ink on that pen of yours. Good luck with the build!

what the OP didnt mention in this thread is that he has $25,000 to spend.

All he has is an ls2 block and some ls3 heads, he could easily sell those and recoupe most of his money and go with something much nicer.


ls3, stroked, forged, mast ls7 heads, fast intake, spec'd cam, he knocking down 600rwhp with driveability to boot

Agreed!^ seems like the best thing he can do is sell what he has now and buy a stroked forged LS3 and go on from there.

yea im def goin with that best bang for my buck cant wait 6 months this will commence

sell the ls2 block but keep the oil pan , front timing and rear covers, keep the ls3 heads and intake you have and get an LS3 stroker bottom end .. good starting point ..

for the same price as a stroker or maybe for a few hundred more, you can resleeve a 5.3 and make a 427.......and have a 4.125 bore......awesome head choices when you get that big of bore

FLYZNTN

Re-sleeve the LS2 block. Go with a 4.125 inch bore.

ERL

Have TSP or ERL (If you go ERL they'll build it then you send them your core) build you a short block with a 4" crank for a 427 or a 4.125 inch crank for a 441.

Port your LS3 heads or sell them and buy an aftermarket set.

You'll hit your number.
