    I have an 87 k5 350 tbi and i was looking at Jim Pace's web site and i was wondering what it would take to get the 383 crate motor that they offer to work with my factory tbi, i want to buy a new motor but not a stock replacement, do you guys have any suggestions ?

    Its next to impossible. Even with custom computer chips sponsered by HotRod magazine, they still couldn't get the motor to run like it was supposed to. At the very minimum you would have to upgrade to a 454 TBI for it to flow enough for that hungry 383 bottom end.
    Far that matter, the stock 350 TBI wont handle much of anything over stock.

    Still trying to figure out why they have brail on drive thru ATM's?? [​IMG]

    Yeah I would go with the 454 TBI. The 383 will probabally run too lean on a stock 350 TBI.
    Then you will still need to get a chip burned. To match the engine.
    The 454 TBI will hook up to all your 350 connections except for the IAC. You will need to get an adapter for that.
    Check out these engines from SDPC<a target="_blank" href=http://www.sdpc2000.com/cart.asp?action=catalog_start&amp;catid=1577>SD 2000 TBI Engines</a>
    Either one of these should run real good on a stock 350 TBI. Altouugh I think I would still get an aftermarket "Performance Chip"
