    I have used those on engines with CAST IRON intakes.Use a good bolt and thread it down as far as possible,and tighten it.The threads will engage more and hold stronger if you tighten them,instead of just firnger-tightening.But in MY OWN persoanl opinion,there is NO WAY that I would use a lift plate on an aluminum intake,especially a big block.6-700 pounds is really not that much weight.Spread the load out over 4 bolts,that's only a little over 150 pounds per bolt.And what are they,5/16" bolts?You could probably do it and be okay,but I wouldn't with an aluminum intake.Cast iron,wouldn't scare me.Just my $0.02

    I have also used them to pull out motors and trannies with the plate bolted to a aluminum intake. It looks scary, but i have never had or heard of one having a problem.

    I read a thing in a magazine years ago about this...don't remember the numbers but it talked about how much weight the 4 5/16 bolts could support and what not...it was a bunch.

    .I have lifted BBC with trans up and my old heads had most of the intake bolts helicoiled and jury rigged...old 074 alum.heads

    Yep i question that too. although i wouldn't do it i often use a 2 bolt lift using the intake manifold bolts, probably weaker than the intake bolts. i don't know which is better, but every time i install an engine i'm scared of dropping it, especially when nothing lines up as it should. What i changed to is a rope that wraps around the front and back of the engine. I know it sounds stupid, but that's the way i do it. I did have a friend who dropped an engine with the carb plate lift and it broke the front crank jurnal, that's what changed my thinking.
    I swore it would never hapen to me.

    A 2 bolt lifting against the shoulders of the bolts is alot stronger than a straight pull against aluminum threads.Just my opinoin.And like I have said before...my opinion and $0.50 will get you a cheap cup of coffee

    lifting engine with carb bolts

    thanks guys for the input. i think i will go with the general opinion(olds 48) and make my own lift plates , 4 separate pieces of metal bolted to back and fronts of heads. Im scarred of that plate and im a firm believer taking a real prudent, safe way to install my baby(engine) the safest way thanks alot chevy art

    I couldn't count the number of engines and engine/trans assemblys I've pulled and installed with a carb. plate and never had a problem, aluminum intakes and all. Think about this, would you trust one bolt that was 1 1/4" diameter because that's what four 5/16" bolts are equal to. I bet your chain isn't that big.
