I know but I've only have had this engine since December 2021 sorry to bother you guys just figured I'd put my 2 cents in because my car runs on E85 has a 102 mm throttle body and a Z11 fuel pump and injectors l know the post is 8 years old and l didn't see a post with these upgrades and just because the post is old doesn't mean this engine has vanished

 

Happy to hear about your GM LS3 crate engine experience. Please keep us up-to-date.

Did you also consider the 525 ASA cam'd version?

 

I was the original owner of a blue 1984 Monte Carlo SS had it 37 years it had a GM performance LS2 with CNC ported LS3 heads crate engine l got from SDPC it had a simular duration cam as the LS3 525 horsepower crate but it had 600 lift a single plane intake and a Holley HP 850 carberator this was in 2008 but sold it in December 2021 and bought a very clean inferno orange 2011 Camaro SS for 15,000 dollars and put 16,000 dollars in upgrades parts not including labor I've had it now 10 months I've made 3 passes with the Camaro in late February 2022 it ran 7.40 at 94mph with full interior and air conditioning with only 3 passes in the eighth mile it is one tenth faster than the Monte Carlo SS was and much more streetable with the built 6L80e automatic transmission with a Circle D 4200 lockup stall converter and 3.27 gears the Monte Carlo had a built 700r4 3000rpm lockup stall converter and a 1986 Buick GN 8.5 reared with 4.10 gears

 

The Camaro has about 1200-1300 miles on the new setup and these times are naturally aspirated it's equipped with nitrous but l haven't used it yet naturally aspirated I'm running 26 degrees timing running E85 need to back off the timing to 19 degrees for a 150 -250 hit but probably will only hit it with a 150 maybe early next year possibly

 

Great to hear from guys with real-world experience. Appreciate the feedback.

 

Periods at the end of your sentences would make it a Hell of a lot easier to read.

 

I thought it was one long sentence…dang. 😜
