    Back in the day, I ran a 1970 LT1 in a Z-28 Camaro... It was a great car and engine. I updated the cam to a Racer Brown STX 21 solid lifter(I believe), and the 350 then made right at 400 horsepower and revved out to 7000. Roller rockers were definitely needed then as the Racer Brown cams increased action, burnt up factory rockers. That cam really brought that engine alive. The factory cam was plain lazy...

    • @albertgaspar627

    Does the LT4 make much more power than a standard LT1? I know they had a hotter cam and slightly better heads and intake. I had a customer for years that had 2 LT4 Corvettes and I was impressed in the 1990's by them. One was built by Doug Rippie though and was a 383. It was the only C4 Corvette that would keep up with the later C5 and C6 cars!

    It's all about airflow. The Gen 1 SBC has 23 degree heads, the Gen 2 LT1 has 21 degree heads, and the LS1 has 15 degree heads. All things even, the compression, cam specs, etc, the LS1 will still out perform them all because it will flow more air, because of the more efficient heads. What I would like to see you test is a SBC with same compression, and same cam specs as the LS1, but with 15 degree heads. Who will win?

I made mine an L-89 but that's just for weight and cool factor. It is 1000% factory in a '67 Corvertte coupe, but I'd happily go up against any engine from back in the day.

    I'd truly be delighted to see more LT1 vids. All things LT1 perhaps??ps ? I've seen "the other guys" vid multiple times already and it was great. So I'm confused. In that vid you claimed the LT1 was even more powerful than a 5.3..

    Hey Richard, I knew a guy back in the mid eighties that had a 350 with Bow tie heads and intake and GM off road cam. Possible to test factory hp parts? 450 hp? I believe it was 12 to 1 with GMs biggest off road cam (worked at a dealership) and would run 12.2 in the quarter with a th350 and 5.13 gears shifting at 7600 rpm in a 67 Chevelle.

      I'll have what you're smoking.
      What factory GM came with 12:1 compression and why would GM make an "off-road" cam? They sold street legal vehicles, not offroad. Even if these magic "factory made" parts existed how would he be able to find them today?

      @@theupscriber65 Sorry but you can look this stuff up. Chevy has been making high performance “Bow-Tie” heads and single plane intakes for years and still does. Chevy also made several off road solid lifter cams with extra duration and lift that were never installed in cars. As for the 12 to 1 I believe he milled the heads to keep the piston weight down but he may have used a dome piston. The car screamed, he even had a mechanical tach mounted on the dash which required a special distributor so cool.

    Just a Edebrock high rise added 20 horse on old 350
    Wheres the push rods High Ram HA HA
    The LS6 Didnt Come out for 10 years lol after LS
    the LT1 rockers were same as old 350 Advertised at 1.5 ratio
    But were actualy 1.324 And ment to be a full roller engine
    That would put lt1 cam at 506 and 520 lift evening up the the LS1 cam
    1st a set of crane gold 1.5 roller rockers
    cause its lift x rocker ratio is actual lift
    the actual specs on lt1 heads were 177 intake and 75 ccs exaust
    Yup They actually exeeded the advertised runner lol
    port match the intake ,heads and exaust and push the port match through intake runner
    pinch point and round golf ball bit the floor of intake runner a hole every quarter inch
    And drill the 4 mm hole in bottom of Throttle body to 6 mm
    or find the 96-97 561 heads thinner casting 200 on ebay lol
    and run 1.5 crane gold roller rockers
    and drill the 4mm to 6mm hole in throttle body .
    cause the little throttle body is maxed 48 actualy with the hole 52 mm
    making it 54 thats 50 more cfm at 6000 rpm .
    Thats just what I call a Tune up vs your LS6 high Ram and let titans Slug it out
    make a great video
