New Short Block
Hey guys, getting ready to do some motor mods. I'm looking at getting the 408 Stroker Short Block from Texas Speed & Performance. No rhyme or reason for using that company, other than thats the cheapest I've been able to find that particular short block with those particular parts. Two questions, #1: Is the 408 a good motor vs. the 383? And #2: Does anybody have any opinions on Texas Speed & Performance, good OR bad??

The 408 is far superior to the 383. The 408 starts out on a 4" bore, whereas the 383 is a stock bore LS1. The 408 will always make more power, have a much better cylinder head selection, and will have fewer issues. Although close in displacement, the 383 always seem to come up short on power for their size, often making no more power than a similarly setup 346. They're oversquare.
I highly recommend Texas Speed. Not once have I had a problem with either their product, customer service, or shipping times. I can't say that for any other company that caters to the LSx.

+1 on Texas Speed. The 408 will be heavier cause it's iron tho.. If you can afford the price jump look into the 402 as well.

Thanks guys!! Yeah that 402 sounds like a pretty good deal also!! Any opinions on my heads?? Looking at porting my stock ls1 heads. I'm on somewhat of a limited budget but I know horsepower costs $$$!!!

Don't have your stock heads ported, it won't save you any money. In fact, it will likely cost more and perform worse. Why buy a 408 short block from TSP if you can buy the longblock?

Funny you should say that!! After making my last comment, I started adding up the cost for all the stuff that we were looking at doing (heads, cam, etc.). I already have the FAST intake and throttle body, bigger injectors and larger fuel delivery system. TSP has a pretty sweet long block package that is looking awfully tempting!!

I'm thinking if I stay N/A I would just go 408 long block too..I thought about a 383 at one time but MOST of the times they dont make anymore power than a 346 H/C/I
