    I checked my carfax thanks to Shawn... and.... it says i have a 305! Its an 87, were 305's even an option or a standard that yr??
    how do i tell if its a 350 or 305..... i dont have a hand booklet thing...
    Hrmm if it is a 305 that would account for the slowness... if its not a 305 then my tiny gears prolly making it slow.

    I run 33"s with 3:73, dual exhaust MSD and a Hypertech Stage 2 chip with a 160' stat. What a ride.
    P.S. I also run a G.M. 350cid, 350 hp crate motor. Like I said, what a ride. You can get all kinds of goodies for your rig from Jamie over at National 4 Wheel Drive in Burlington, Ontario. 1-800-575-7500. Best prices and great service

    is that in a pickup or a k5? I know they had some 305's in the pickups, but as far as I was aware of you couldn't get a 305 FI in the 87 and up Blazers. I couold be wrong though...

    The block has a casting number in the back, on the driver side, just behind the cylinder head. You may have to scrape off some crud.

    Post that number and I can tell you what it is.

    I dunno how right carfax is... it said I had flood damage in 99 and I owned it then and um, well, I don't recall being in a flood... also another person on here SarazK5 did her Honda and it stated her car was never wrecked... yet when she bought it the front was smashed in on it... so who knows how right it all is?

    The one on mine fit pretty well with what I knew about it already - really screwed up mileage figures, and a 305 as OEM. With the wreck, the only way they'd know was if an anal retentive dealer did repair work on it - nobody else would bother reporting/recording it.

    Sure could get a TBI 305 in '87. That's what I've got. Verified from the VIN (8th digit is "H" for the TBI 305), the under-hood emissions sticker, and the sticker in the glovebox with all the option codes (LO3 is the 5.0L TBI).

    "How much does a 350 cost including installation"

    Anywhere from $50-$10,000, depending on what you want.

    I suggest you change your gears. It will net more of a performance increase in my opinion than a 350 will.

    Ditto - the 305 TBI isn't too bad of a motor. A little more gear, and it'll do purty good.
