    I have a 1987 Chevy k5 with a TBI 350, I installed a tachometer by using the hot wire located on the ignition coil. It works great at idle and only goes up to 1000rpm before it jumps to 3000rpm. So I thought it would just be 2000rpm off but when I floor it and it down shifts to a high rpm, it...

    I have an 89 Chevy C15. 350/ 700R. It has 200K on it. I bought it with a blown engine (they let it run out of oil. Bad valve cover gasket.) So I knew it needed a new engine when I bought it. I ordered a crate motor from Summit. Great fit, easy swap. With the new engine I installed new O2...

    I just purchased my first car ever, and made it one that's been a dream car since I was a kid. I bought a 1989 Caprice 9c1 with the 350 TBI engine. I don't have very much knowledge about this thing or how the TBI works, but my plan is to slowly build it out to be a fun cruiser (and burnout...

    I have seen a few Elgin cams mentioned here, If I can't put a GM roller cam/lifters in my 1995 Yukon 5.7 L05 TBI block, I am curious which one of the following three would be the best from idle to 3,000 RPM, (the zone I drive/tow with my Yukon) CAM# W/1.5 LIFT @.050 Opens Closes...

    I have some freshly rebuilt 191 chevy swirl port TBI heads that I'm planning on using for my engine build. I've heard these are terrible heads, but most of the time the people that say this have never used them. I've also heard that they pull hard to 5000 rpm or more. This 350 will be going into...

    Hi, My 1980 Trans Am is running a 305 (non-turbo) linked to a TH350, where as my 1985 Chevy Van20 has a 350 (TBI) linked to a TH400. What I intend doing is swapping the engines, along with the tranny, between the two cars however my concern is blowing up the ECU in the process. I don't want...

    I am going through this problem, this now makes the second time that I have had this happen, that when I go to start my truck, it will not roar to life but crank and crank. The engine keeps flooding just from trying to start it, it does this by me not touching the gas pedal :confused:. And I...

    I just built a 383 stroker. It's now in an '88 Chevy Blazer 4x4. It had a stock 350. I bought a tbi from a friend. The ports are bigger on the new tbi then the stock one. I need to bolt it to the stock intake. I have a tbi spacer with the stock tbi port size. Is there an adapter that will funnel...
