    Hello All!

    It has been a while. My 79 Camaro is tucked away in the corner of my shop waiting for me to do something with it. A coworker of mine pulled a 454 with TH400 out of a mid 80s motorhome last weekend and he is looking to sell it. He says it has 60k miles on it and ran and drove before pulling it. I have been looking for a BBC for the Camaro for a while now. Is this a good fit for the car? (Decent 454s in the 80s? Will the trans fit?) What would you all put as a fair price on the pair?

    Thanks again.

    Low compression, low horsepower. It will have the smaller "peanut" port heads which aren't very good, oval port are better for the street as opposed to rectangular port heads. But this depends on what you're planning to do with the car. The turbo 400 will fit but you'll need a different cross member. Your turbo 350 will work if you simply "drive"it. If you want the "look" factor, get the bugs worked out and you can get it for a decent price, maybe $500-$600 for both, why not. But if you want to tear up the streets just buy the engine and build it up the way you want. Then you can install it when ready. Be sure and take every bracket/pulley/etc to make the swap easier, saves a lot of aggravation.

    ^^That pretty much sums it up. Unless you're willing to drop some money into that anemic big block, you'll only have the looks, but will get blown away by most small blocks.

    More like LS engine lol.

    I paid $500 for my 454 too, peanut heads, low compression etc. Ended up buying a Gen V 454 block, bought all the goodies and ended up dumping it all for my first LS1.


    There is a cool factor with the 454. It has the same “bolt” on areas as a SBC so SBC transmissions will fit.

    According to TCI, the TH400 was made in 3 different lengths. A motorhome would likely have one of the longer ones while the TH400 originally put in Camaros would likely be the shorter one. Something to check before trying to use it.

    I would like to interject something here. My .030 454 with 236 peanut port heads, air gap, 282S CC cam, 1 3/4" headers, 7.9 compression with a variety of carburetors tried on it. Ran mid to high 11's@ up to 112mph. Those 454's are just junk along with turbo 400's, better get a nice 350 LOL.

    Go look at my thread on peanut port vs oval port heads, you will get a surprise.

    112mph is not a ton of Hp. Are these times in a stripped down drag car w/slicks? 112mph is typically a hooking low 12 car.

    MPH never won a race, ET wins the race. There is a lot of variables for MPH but torque moves the car, HP keeps it going down the track. My car is not stripped down except for a fiberglass hood and a drivers only seat, it does weigh over 3500 with a BBC in it. If you take my same combo and up the compression to 12 to 1 with no other changes the car should go 11 teens at 118 to 120mph. Ask the C5 Vette owner on how he lost a race to me when I spanked his LS engine running 119mph with an 11.80@111mph to his 12.29, here in another one. When I had my pump gas 358 in the car on race day it mostly ran 11.50's@116, in the other lane was a 63 Impala 5.3 with twin turbos and it was a heads up race, this is no lie, I had to let up on the gas to keep from going under the index and I still beat him with his almost 130 some mph that day. Sure he makes more HP than I do but his car comes out of the hole like a wet blanket. look at all the Stock and Super Stock cars, what do you see? killer launches with ineradicable 1/8 mile times. My buddies 69 Camaro has a 461 PP engine, he also ran 112 to 113mph and his engine dynoed 547hp, but his 1/8 mile times were 7.17@96mph and his car has 4.88 gears (MPH killer). So I think if this guy buys the 454 and turbo 400 he will be pretty happy, he just needs to add a few extras to be happy with it.
