    Xtreme Blazer V8 LS swap

    Hey guys heres my project

    Here is a little background on the blazer
    Its a Yellow 2002 S10 Blazer Xtreme it had 36k miles on it when i bought it well shortly after buying it i started modding it and got it at its fastest to run a 15.8 1/4 time and i didn't like the way the motor sounded or performed. I started researching what i could do to fix this and i ran across the LS swap and i was hooked. Well needless to say i ended up blowing the V6 and decided to just do the swap.

    Original Plans:
    Stock 5.3
    Stock truck intake
    Stock truck manis
    Stock 4.3 pulley set up rigged to work
    Salvage computer and harness rewired to work by me

    I started this swap over at my buddies house and i was sitting over there one day sweating my ass off in the mid day summer sun and was looking at this rusty nasty looking swap and i said to my self i didn't want this for my car which at the time only had 76k miles on it and i had always taken good care of it well i said f@#^ this and took the swap over to my house and put it in the garage and started planning out the swap the way i wanted it.

    The new and current plan
    02 LM7 5.3
    Texas Speed and Performance Heads and Cam Package
    Which included PRC Stage 2.5 heads 2.02/1.575 stanless valves with 59cc combustion chambers CNC porting with PRC double valve springs good to a .660lift, 7.400 chromemoly pushrods, LS6 ported oil pump, Rollmaster double roller timing chain and a comp cams 224/224 .581/.581 111LSA+2 cam.
    LS2 oil pan from GM with dipstick and tube pickup and windage tray
    LS2/LS7 front drive accessories
    LS2 water pump kit
    LS2 harmonic balancer
    LS1 intale that has been smoothed filled and painted
    Sanderson Shorty Swap Headers with 2000 deg coating
    Current performance engine harness and custom bench tune
    Current Performance Swap Radiator
    Performabuilt Stage 2 trans
    B&M trans cooler with temp controled fan
    Braided stanless steel lines
    02 S10 2.2L Flex Fuel filter regulator
    MSD 8.5s
    thats all i can think of now on to the pictures

    This is the motor when i first started the swap 2 years ago over at my buddies.

    When i started i didn't even know enough about the swap to know that i had to take the front clip off.



    This is the motor in the blazer when i brought it over to my house

    I then took the motor and trans out put the motor on the stand and started working on the frame i cut a notch for the LS2 oil pan and for the LS2 A/C compressor

    The paint plans on the motor are Black block, intake, valve covers, coils and inner fenders all gloss black.
    The fuel rails, throttle body, throttle cable bracket, coil bracket, computer, fuse relay center all color matched yellow in a dupont nason base clear.

    Well i had to take the LS2 balancer back and get a LS1 corvette balancer and i think its going to work. I used the extra money in the difference in the price between the LS2 balancer ($189) and the LS1 balancer ($77) i bought an interior driverside door handle and a GM performance parts catalog and they gave me 26 bucks back that was nice lol. Well here is some pics of the balancer and what not.




    Here is the Harland Sharp roller rockers 1.7:1

    i'm not sure i used a desktop dyno that had stupid amount of info it needed to make the calculation like intake port volume intake port flow CFM at what lift what cam everything and it ended up with 538 flywheel horse but being that i have a stock LS1 intake i would bet 460 or so at the flywheel then with the drivetrain loss it'll be high 3's low 4's at the wheels. which puts me at low 12's till i get the fast 92/92 intake then i'll be in the 11's

    I have a little over $8,250 in it to get to here and i need another $5,000 or so to finish... As far as plans for the rear end i will upgrade that after i get done with the swap and get the bugs worked out. I have been looking at a detroit true track diff with the same gear ratio maybe upgrade the gears with moser axles thats probably all i'm going to do with the rear. It has 3.42 gears with factory limited slip it'll hold for a little while.
